But it should be noted that the installation of said works is not without consequences for the countries concerned. Benin, a country in the Gulf of Guinea, is no exception to this phenomenon because, due to its maritime history, it has a heritage of port structures. These structures, built on its coastline, cause a wide variety of environmental problems such as silting and erosion on either side of them. The general objective of this article is to contribute to the proper functionality of port facilities while minimizing environmental problems that may arise. It aims to provide managers with a tool allowing them to fully understand the state of their assets in order to rationalize maintenance actions. In order to achieve this objective, an assessment of the state of the structure, and then a structural diagnosis are necessary and recommendations can be established to restore the level of service of the latter. As a result, two examples were presented: the wharf of the Sèmè-Podji pipeline project and the maritime piles project of the Wasco de Gama bridge (control project), and recommendations adapted to this objective were established. The comparative analysis of the two examples, both maritime works, revealed an under-sizing at the level of the spans of the wharf bridge of the Sèmè-Podji pipeline project (spans of 7 m in length), while these spans vary on average by 45 m to 62 m for the Wasco da Gama bridge. Bringing the piles closer together at the Sèmè-Podji wharf reduces the energy of the current which promotes the accumulation of sediment. The structure no longer experiences a flow capable of setting in motion the sands accumulated since at least 2022. This element appears to be a fundamental characteristic explaining the erosion observed to the east of the structure.展开更多

However, understanding the criteria used for traditional nomenclature of fungi, particularly wild edible mushrooms across linguistic groups, remains limited, leading to frequent errors in species recognition. This study seeks to assess how linguistic affiliations influence the local naming of useful wild mushrooms, and is the first of its kind in Benin. In order to understand how local people recognize, classify and name mushrooms that develop in or close to their villages, 2234 respondents from five socio-linguistic groups across three geographical areas were interviewed. Structured and semi-structured interviews were conducted to gather data on the local naming criteria for edible wild mushrooms. Citation scores were recorded for both nomenclature criteria and species, considering variables such as linguistic groups, age, and language. Twenty-two nomenclature criteria were used by local people to name edible wild species. Strong similarity in classification and naming of species was shown in 97% of the languages, while 3% showed differing classification criteria. The Gur, Atlantic, and Mande linguistic groups demonstrated more comprehensive traditional taxonomic and nomenclatural knowledge, sharing six common criteria: texture, taste, size, kingdom (Fungi), form, and substrate. Overall, local populations possess extensive knowledge regarding the diversity of wild edible mushrooms in their environment.展开更多

The lithofacies recognised are: conglomerates, debris flow deposits, very coarse grained sandstone, ferruginous cross bedded sandstone, siltstone, shale/clay and massive sand. The lithofacies were interpreted in terms of sequence stratigraphic elements with the recognition of sequence boundaries characterised by distinct facies dislocations and subaerial exposures. Four depositional sequences (DS I to DS IV) were identified. Depositional sequences (DS I) exhibited a complete regressive–transgressive cycle comprising LST, TST and HST, while DS II to DS IV were incomplete comprising of sediments interpreted as LST deposits. On the basis of the depositional facies and sequence stratigraphic elements, the sediments in the area of study are interpreted as predominantly of Ilaro Formation while fewer exposures are sediments of the Coastal Plain Sands/ Benin Formation. This observation suggests a re-interpretation of the Tertiary sedimentary successions, which hitherto recognised all the sediments in the area of study as Coastal Plain Sands.展开更多

Major ions have been employed with statistical methods to identify geochemical processes controlling groundwater quality. Multivariate statistical analysis (principal component analysis “PCA” and hierarchical cluster analysis “HCA”) revealed the main sources of groundwater mineralization. According to the hydrochemical data and the methods of treatment, groundwater mineralization in the investigated aquifer is caused by four main processes: 1) mixing with Nokoué lake and Porto-Novo lagoon salt water causing salinity to increase in the southern part of the aquifer;2) anthropogenic activities;3) cation exchange process;and 4) soil CO2 diffusion providing a large proportion of bicarbonates.展开更多

Because of its involvement in the genesis of certain cancers, the WHO has classified Hp in the category of carcinogen class I. The aim of this study was to determine the prevalence of Hp infection among children from a District in Northern Benin, and to identify the factors associated with it. Patients and methods: This scientific investigation is a cross-sectional, descriptive, and analytical study based on a prospective collection of data carried out from July to September 2018. Recruitment was probabilistic;it was based on the WHO cluster sampling technique implemented among children aged 3 to 10 years without recent history of antibiotic treatment and proton pump inhibitors. Hp infection was diagnosed during the search for bacteria antigen in the feces through a quick Elisa test which proved positive. Results: We included 250 children in the study. Among them, 151 (60.4%) had Hp infection. 79 (52.3%) out of the 151 infected children were female, i.e. a sex ratio of 0.91. Mean age for those infected children was 6 ± 2.3 years. Among the 151 children infected with Hp, 98 (64.9%) were asymptomatic. Factors associated with that infection were: children’s age > 5 years (p = 0.0461), use of contaminated drinking water (p = 0.0001), meals away from home (p = 0.0039), mothers’ low educational status (p = 0.0137) and low monthly income (p = 0.0116) as well as household size > 3 (p = 0.0002). Conclusion: Hp infection is common among children aged 3 to 10 years in Northern Benin. Often asymptomatic, it is facilitated and exacerbated by unsanitary conditions and low socioeconomic status.展开更多

Materials and Methods: Of the 150 clinical samples (Ear swab, Urine, Wound swab, Sputa and Semen) received at Lahor Research Laboratory and Medical center in Benin City, between January 2010 and December 2012, 36 (24%) yielded significant growth of P. aeruginosa. Samples were cultured on MacConkey and Blood agar. Clinical isolates were identified using standard method. Antibiotics susceptibility test employing agar disc diffusion method was used. Clinical isolates were subjected to Plasmid DNA profiling and curing test was carried out at Lahor Molecular Laboratory. This was followed by a post plasmid curing susceptibility test. Agarose gel electrophoresis was carried out to separate the Plasmid DNA using standard method. Bands were visualized using UV illuminator. Results: Wound swabs had the highest numbers of clinical isolates of P. aeruginosa (55.6%) followed by Urine, Semen, Sputa and Ear swab (19.4%, 11.0%, 8.3%, and 5.6%) respectively. Before the isolates were cured of their plasmid, 39% of the P. aeruginosa strains were found to be resistant to Ciprofloxacin (CPX), 47%, Ofloxacin (OFX), 44% Pefloxacin (PEF) and 56% Sparfloxacin (SPX). After plasmid curing, the new antibiogram of the isolates showed that some clinical isolates that hitherto were resistant to a given Fluoroquinolone became susceptible, 36% to CPX, 12% to OFX, 12.5% to PEF and 15% to SPX. Agarose gel electrophoresis carried out on the Plasmid DNA revealed that there was detectable Plasmid DNA in 13.9% of the clinical isolates analyzed. Conclusion: There is an alarming increase of clinical infections caused by multidrug resistant strains of P. aeruginosa.13.9% of the multidrug resistance strains of P. aeruginosa in Benin City were Plasmid mediated. Treatment should be based on current Laboratory Susceptibility Test results of the isolates.展开更多

Objective: To determine the clinical, therapeutic and prognostic aspects of obstetric fistula at CHUD/B-A maternity ward in 2016. Study Method: This is a descriptive, analytic study with prospective data collection from March 07 to December 31, 2016. Patients with obstetric fistula were the study population. Results: A total of 37 patients were treated including 35 operated, the other two not operated for pyuria and bladder calculus after examination under spinal anesthesia. The average age was 36.6 ± 10.5 years with the extremes of 21 years and 65 years. The mean age of onset of Obstetric Fistula (OF) was 28.9 ± 6.5 years. Patients came from southern Benin (51.4%), were married (67.6%), peasant (35.1%) and out of school (81.1%). The types of OF were vesico-vaginal fistula (VVF) (62.2%), urethro-vaginal fistula (24.3%), vesico-uterine fistula (VUF) (5.4%), and uretero-vaginal fistula (2.7%). The fistula site was supra trigonal (54.1%), urethral (18.9%), trigonal (10.8%), vesico-uterine (10.8%), cervical urethral (2.7%), ureteroid vaginal (2.7%). Fistulas were complex (70.3%), complicated (24.3%) and simple (5.4%). The vaginal route was one of the first routes (64.9%). The operative techniques used were CHASSAR MOIR hysterorrhaphy (74.3%). The cure with continence was 68.6%. Conclusion: OF is observed in young women of childbearing age. VVF is the most common. The management is surgical with several operating techniques. Healing is possible. Hence the importance of paying special attention to these patients for their care.展开更多

The study shows that social identity salience was dynamic and played an important role in the emergence and escalation of conflict in the studied cases. Conflicts emerged when identities became salient as a result of the stake-holders’ framing of contextual factors as a threat to their identity. The conflicts escalated when decisions and actions undertaken in the management process were framed as top-down and as posing a threat to the identities of the stakeholders. We conclude that, although the government in the management of the protected areas introduced participation, unilateral decisions taken about the way the conflicts should be managed caused disappointment and distrust, and thus led to a greater distance between the parties involved and to conflict escalation.展开更多

This study aimed at assessing the effect of cropping systems and slope on soil physical and chemical properties in the watershed of Kpacomey located in the Aplahoué district. Soil samples were collected from three parallel transects along the slope. Sampling was carried out under different treatments combining cropping systems (Maize-Cassava, pure Palm grove, Palm grove-Maize-Cassava and Teak Plantation) along with slope levels (low slope, medium slope and high slope degree). The impact of cropping systems and slope on soil properties was assessed by determining the physical and chemical parameters. The cropping systems significantly (p < 0.05) influenced soil bulk density, root biomass, soil acidity and soil organic matter. The lowest soil bulk density (1.38 g/cm<sup>3</sup>) was recorded under the Palm grove-Maize-Cassava cropping system while the highest (1.47 g/cm<sup>3</sup>) was obtained with pure Palm grove cropping system. Root biomass was more abundant (0.28%) with the pure Palm grove cropping system. However, root biomass was significantly (p < 0.05) influenced by slope. Soil crusting resulted in no significant influence (p > 0.05) on the effect of cropping systems and slope. Moreover, cropping systems resulted in significant effects (p < 0.05). Soil organic matter and soil-assimilated phosphorus content were significantly influenced by the effect of the slope. These findings indicated that cropping systems and slope are significant drivers in soil degradation in the Kpacomey watershed and bringing out cropping systems that best aim at soil conservation.展开更多

The objective of this study was to investigate the morphological diversity of maize accessions and its structure on the basis of 14 variables. For the experimentation, 43 and 98 maize accessions were planted in three replicates respectively in central and northern Benin following an incomplete randomized block. The mixed model analysis of two factors variance revealed a significant difference for all accessions considering each agro-morphological characteristic evaluated except the germination day of two areas seed accessions. The numerical classification grouped the accessions into four groups in each zone. The stepwise discriminant analysis showed that early characters related to plant height and ear insertion were the variables that discriminated accessions in both zones. Maturity and recovery ears, sensitivity to streak and the germination days are the variables that discriminate accessions of the two areas. These results provide a database for the creation of improved maize varieties that meet the needs of展开更多

Toho Lake, located to the south east of Benin, is threatened by pollution emanating from anthropogenic activities with the use of chemical fertilizers, effluent of domestic waste, particularly human and animal excrement with neighbourhood effluents. This study aimed at assessing some heavy metals in fresh fish (Oreochromis aureus) of Toho Lake in order to secure healthy food for the population and protect the ecosystem. Samples of water and fishes were collected and analyzed by HACH DR 3900 after treatment. Results revealed a mean oxygenation of water (4.95 mgo2/l), Biochemical Oxygen Demand (21.5 mgo2/l), Chemical oxygen Demand (149, 39 mg/l) with the nitrogen in Nitrate (NO3: 0.18 mg/l), ammonium nitrate (N-N: 0.47 mg/l), and phosphorous (2.06 mg/l) to be very high. The highest contents of heavy metals obtained in the fresh fish were cadmium (32.25 mg/kg), copper (115 mg/kg), lead (8.25 mg/kg), and zinc (90.75 mg/kg) and revealed that the fishes of Toho lake were polluted. The finding allowed us to conclude that the pollution of the lake and the fish carnage are due to anthropogenic pollution through chemicals spilling. Some protection methods of the lake and ecosystem are proposed in order to keep the fish safe and protect the well-being of the population.展开更多

Objective: Calculate the frequency of hypovitaminosis D in children aged 6 to 59 months suffering from severe malaria in the CHUD-P pediatric unit in 2016. Setting and Methods: This research work is a cross-sectional study with descriptive and analytical purposes. Data gathering was prospective. The study involved children aged 6 to 59 months hospitalized for severe malaria in the CHUD-P pediatric unit. The said children were HIV-uninfected, eutrophic and had not received vitamin D supplementation during the last 6 months. Vitamin D dose was measured using the High Performance Liquid Chromatography (HPLC) technique. Results: A total of 80 subjects were involved in the survey. Mean age was 26.08 months, sex ratio was 0.8 and average weight was 10.80 kg. Hypovitaminosis D frequency was 83.8% (67 cases out of 80 children investigated during the survey) with an average plasma concentration of vitamin D estimated at 21.57 ng/ml ± 7.34 with two extremes (11.24 - 42.32) ng/ml. The minimum parasitaemia was 202 P/μl and the maximum was 580,000 P/μl. Conclusion: Hypovitaminosis D is common in children suffering from severe malaria;this result suggests conducting a large-scale community-based study to decide on vitamin D inclusion in national supplementation policies and severe malaria management.展开更多

Material and Methods: This was a descriptive cross-sectional study that took place over a period of 4 years and 4 months (52 months) from January 1<sup>st</sup> 2017 to April 30<sup>th</sup> 2021. All cases of urogenital trauma treated in the General surgery department during the period were collected. Patient records, hospitalization registers and operating reports were used to collect information. Data entry was done using Epi data 3.1 software, French version. The analysis was performed using MedCalc software (version 19.4.1. Mariakerke, Belgium), and Epi info software version 7. Results: In 52 months, 75 cases of urogenital trauma were collected. The prevalence of urogenital trauma was 1.1% of admissions with an annual incidence of 17.3 cases. The modal age class was [20;40], i.e. 49.3%. Males accounted for 76.0% (n = 57) of cases. Urethral and kidney injuries were found in 33.3% and 21.3%, respectively. The external genitalia was involved in 24.0%. Road traffic accidents occupied the first place with 62.6%. Kidney lesions were revealed by lumbar pain in 62.5% (n = 10) and post traumatic hematuria in 25% (n = 4) of cases. Most of the patients (n = 8, i.e. 50%) were classified as grade I according to the AAST classification. Conclusion: Urogenital trauma is common in our environment and can be life-threatening. Knowledge of their epidemiology will allow for prevention and good management.展开更多

The objective of this study is to visualize flooding risk of municipalities at the intersection of the coastal sedimentary zone and the crystalline surface. The methodology adopted is based on geomatic approach, which involves documentary research, processing and assisted classification using remote sensing images and multi-criteria analysis of the Geographic Information System (GIS). Flooding risk is very high at 8.85% in Djidja, Toffo, Zè and Bonou municipalities. In other municipalities such as Agbangnizoun, Abomey, Bohicon, Za-Kpota and Cove, it is high of 46.85%. To the Southeast of the study area, it is located on the eastern and western banks of Oueme Valley. The medium risk represents 26.35% and is located in the municipalities of Ouinhi and Adjohoun. The other municipalities have a low rate of 17.95%. Risk modeling has made it possible to access the various levels of rising water that can cause flooding. Land-use planning decisions can be influenced by the results of this study.展开更多

The aims of the study were to develop solid biostimulants based on five rhizobacteria native to Benin’s soils and to evaluate their efficacy on the growth and biomass yield of maize under greenhouse conditions on ferrallitic and ferruginous soils. Clay and peat were used as a conservation binder for the preparation of the biostimulants. These binders were used alone or combined in the different formulations with maize flour and sucrose. 10 g of biostimulants were applied at sowing in pots containing five kilograms of sterilised soil. The experimental design was a completely randomised block of 24 treatments with three replicates. The results obtained showed significant improvements (<em>P</em> < 0.001) in height (49.49%), stem diameter (32.7%), leaf area (66.10%), above-ground biomass (97.12%) and below-ground biomass (53.98%) on ferrallitic soil with the application of the clay + <em>Pseudomonas putida</em> biostimulant compared to the control. On the other hand, the use of the peat biostimulant + <em>Pseudomonas syringae</em> was more beneficial for plant growth on ferruginous soil. The height, stem diameter, leaf area, above-ground biomass and below-ground biomass of the plants under the influence of this biostimulant were improved by 83.06%, 44.57%, 102.94%, 86.84% and 42.68%, respectively, compared to the control. Therefore, these results confirm that Rhizobacteria express their potential through biostimulants formulated on maize. The formulated biostimulants can later be used by producers to improve crop productivity for sustainable agriculture.展开更多

To analyze the epidemiological aspects of the cholera outbreak in endemic areas in Benin. The study is a retrospective investigation on 2560 data of cholera patients received in health facilities from 2012 to 2016 in Benin. Besides, a prospective study was conducted. This prospective study includes 513 person (health professionals, community workers and people exposed to cholera) of five different areas of the country. It was conducted from April 10 to May 10, 2017. A survey was conducted over 513 in order to collect data on cholera symptoms, hygiene guidelines suggested by the respondents, excreta disposal, drinking water, household waste management and direct observation. Software R 3.4.0 was used for simple correspondence factor analysis (CFA). From 2012 to 2016, 16.48% of samples were taken and 48.34% were positive for <i>Vibrio cholera</i> O1, <i>El Tor biotype</i>, <i>Ogawa serotypes</i>. The Littoral area is leading in the number of cases (33.83%) followed by Atlantic (23.75%), Ouémé (16.79%) and Colline (8.91%). The survey revealed that the exposed populations are unaware of the symptoms of cholera and do not perceive the quality of drinking water as a strong guidance in the prevention of cholera. Nevertheless, the majority of respondents (86%) are aware for the best times to wash their hands and know that they need to go to hospital in case of symptoms. Our study highlights the persistence of vulnerability factors to cholera in the targeted population, despite a good knowledge of prevention rules among staff and the population.展开更多
文摘1 In the heart of Akpro-Misserete,a small town roughly 40 kilometers from Cotonou,the sounds of feet pounding the earth and unified shouts of“Hay-Hah!”fill the air.Inside a modest martial arts club,students of all ages follow the lead of Damien Agossou Degbo,a 53-year-old martial arts master and cultural ambassador.For him,Chinese martial arts are more than physical training-they are a lifestyle connecting Benin with China's ancient traditions.
文摘Port structures constitute the main link in the maritime transport chain of coastal countries and therefore contribute to their economic development. But it should be noted that the installation of said works is not without consequences for the countries concerned. Benin, a country in the Gulf of Guinea, is no exception to this phenomenon because, due to its maritime history, it has a heritage of port structures. These structures, built on its coastline, cause a wide variety of environmental problems such as silting and erosion on either side of them. The general objective of this article is to contribute to the proper functionality of port facilities while minimizing environmental problems that may arise. It aims to provide managers with a tool allowing them to fully understand the state of their assets in order to rationalize maintenance actions. In order to achieve this objective, an assessment of the state of the structure, and then a structural diagnosis are necessary and recommendations can be established to restore the level of service of the latter. As a result, two examples were presented: the wharf of the Sèmè-Podji pipeline project and the maritime piles project of the Wasco de Gama bridge (control project), and recommendations adapted to this objective were established. The comparative analysis of the two examples, both maritime works, revealed an under-sizing at the level of the spans of the wharf bridge of the Sèmè-Podji pipeline project (spans of 7 m in length), while these spans vary on average by 45 m to 62 m for the Wasco da Gama bridge. Bringing the piles closer together at the Sèmè-Podji wharf reduces the energy of the current which promotes the accumulation of sediment. The structure no longer experiences a flow capable of setting in motion the sands accumulated since at least 2022. This element appears to be a fundamental characteristic explaining the erosion observed to the east of the structure.
文摘Traditional taxonomic sorting of samples into recognizable taxonomic units, such as morphospecies or morphotypes, is commonly relied upon in conservation biology and ethnobiological studies. However, understanding the criteria used for traditional nomenclature of fungi, particularly wild edible mushrooms across linguistic groups, remains limited, leading to frequent errors in species recognition. This study seeks to assess how linguistic affiliations influence the local naming of useful wild mushrooms, and is the first of its kind in Benin. In order to understand how local people recognize, classify and name mushrooms that develop in or close to their villages, 2234 respondents from five socio-linguistic groups across three geographical areas were interviewed. Structured and semi-structured interviews were conducted to gather data on the local naming criteria for edible wild mushrooms. Citation scores were recorded for both nomenclature criteria and species, considering variables such as linguistic groups, age, and language. Twenty-two nomenclature criteria were used by local people to name edible wild species. Strong similarity in classification and naming of species was shown in 97% of the languages, while 3% showed differing classification criteria. The Gur, Atlantic, and Mande linguistic groups demonstrated more comprehensive traditional taxonomic and nomenclatural knowledge, sharing six common criteria: texture, taste, size, kingdom (Fungi), form, and substrate. Overall, local populations possess extensive knowledge regarding the diversity of wild edible mushrooms in their environment.

文摘Detailed fieldwork in parts of the Benin (Dahomey) Basin SW, Nigeria has allowed the recognition of sedimentary successions deposited in different continental depositional environments interpreted as fluvial sedimentation characterised by abandoned channels and subaerial exposure features. The lithofacies recognised are: conglomerates, debris flow deposits, very coarse grained sandstone, ferruginous cross bedded sandstone, siltstone, shale/clay and massive sand. The lithofacies were interpreted in terms of sequence stratigraphic elements with the recognition of sequence boundaries characterised by distinct facies dislocations and subaerial exposures. Four depositional sequences (DS I to DS IV) were identified. Depositional sequences (DS I) exhibited a complete regressive–transgressive cycle comprising LST, TST and HST, while DS II to DS IV were incomplete comprising of sediments interpreted as LST deposits. On the basis of the depositional facies and sequence stratigraphic elements, the sediments in the area of study are interpreted as predominantly of Ilaro Formation while fewer exposures are sediments of the Coastal Plain Sands/ Benin Formation. This observation suggests a re-interpretation of the Tertiary sedimentary successions, which hitherto recognised all the sediments in the area of study as Coastal Plain Sands.
文摘In southern Benin, where population is growing and water demand for domestic activities is increasing, water balance assessment constitutes a serious concern about sustainability of water resources. Major ions have been employed with statistical methods to identify geochemical processes controlling groundwater quality. Multivariate statistical analysis (principal component analysis “PCA” and hierarchical cluster analysis “HCA”) revealed the main sources of groundwater mineralization. According to the hydrochemical data and the methods of treatment, groundwater mineralization in the investigated aquifer is caused by four main processes: 1) mixing with Nokoué lake and Porto-Novo lagoon salt water causing salinity to increase in the southern part of the aquifer;2) anthropogenic activities;3) cation exchange process;and 4) soil CO2 diffusion providing a large proportion of bicarbonates.
文摘Background: Hp infection is the most common chronic bacterial infection in developing countries and is contracted especially in childhood where it remains silent. Because of its involvement in the genesis of certain cancers, the WHO has classified Hp in the category of carcinogen class I. The aim of this study was to determine the prevalence of Hp infection among children from a District in Northern Benin, and to identify the factors associated with it. Patients and methods: This scientific investigation is a cross-sectional, descriptive, and analytical study based on a prospective collection of data carried out from July to September 2018. Recruitment was probabilistic;it was based on the WHO cluster sampling technique implemented among children aged 3 to 10 years without recent history of antibiotic treatment and proton pump inhibitors. Hp infection was diagnosed during the search for bacteria antigen in the feces through a quick Elisa test which proved positive. Results: We included 250 children in the study. Among them, 151 (60.4%) had Hp infection. 79 (52.3%) out of the 151 infected children were female, i.e. a sex ratio of 0.91. Mean age for those infected children was 6 ± 2.3 years. Among the 151 children infected with Hp, 98 (64.9%) were asymptomatic. Factors associated with that infection were: children’s age > 5 years (p = 0.0461), use of contaminated drinking water (p = 0.0001), meals away from home (p = 0.0039), mothers’ low educational status (p = 0.0137) and low monthly income (p = 0.0116) as well as household size > 3 (p = 0.0002). Conclusion: Hp infection is common among children aged 3 to 10 years in Northern Benin. Often asymptomatic, it is facilitated and exacerbated by unsanitary conditions and low socioeconomic status.
文摘Aim: To determine the Plasmid DNA profile of the multidrug resistant strains of Pseudomonas aeruginosa in the clinical isolates. Materials and Methods: Of the 150 clinical samples (Ear swab, Urine, Wound swab, Sputa and Semen) received at Lahor Research Laboratory and Medical center in Benin City, between January 2010 and December 2012, 36 (24%) yielded significant growth of P. aeruginosa. Samples were cultured on MacConkey and Blood agar. Clinical isolates were identified using standard method. Antibiotics susceptibility test employing agar disc diffusion method was used. Clinical isolates were subjected to Plasmid DNA profiling and curing test was carried out at Lahor Molecular Laboratory. This was followed by a post plasmid curing susceptibility test. Agarose gel electrophoresis was carried out to separate the Plasmid DNA using standard method. Bands were visualized using UV illuminator. Results: Wound swabs had the highest numbers of clinical isolates of P. aeruginosa (55.6%) followed by Urine, Semen, Sputa and Ear swab (19.4%, 11.0%, 8.3%, and 5.6%) respectively. Before the isolates were cured of their plasmid, 39% of the P. aeruginosa strains were found to be resistant to Ciprofloxacin (CPX), 47%, Ofloxacin (OFX), 44% Pefloxacin (PEF) and 56% Sparfloxacin (SPX). After plasmid curing, the new antibiogram of the isolates showed that some clinical isolates that hitherto were resistant to a given Fluoroquinolone became susceptible, 36% to CPX, 12% to OFX, 12.5% to PEF and 15% to SPX. Agarose gel electrophoresis carried out on the Plasmid DNA revealed that there was detectable Plasmid DNA in 13.9% of the clinical isolates analyzed. Conclusion: There is an alarming increase of clinical infections caused by multidrug resistant strains of P. aeruginosa.13.9% of the multidrug resistance strains of P. aeruginosa in Benin City were Plasmid mediated. Treatment should be based on current Laboratory Susceptibility Test results of the isolates.
文摘Introduction: Obstetric Fistula (OF) is a tragedy and a public health problem (physical, social, moral and psychological). Objective: To determine the clinical, therapeutic and prognostic aspects of obstetric fistula at CHUD/B-A maternity ward in 2016. Study Method: This is a descriptive, analytic study with prospective data collection from March 07 to December 31, 2016. Patients with obstetric fistula were the study population. Results: A total of 37 patients were treated including 35 operated, the other two not operated for pyuria and bladder calculus after examination under spinal anesthesia. The average age was 36.6 ± 10.5 years with the extremes of 21 years and 65 years. The mean age of onset of Obstetric Fistula (OF) was 28.9 ± 6.5 years. Patients came from southern Benin (51.4%), were married (67.6%), peasant (35.1%) and out of school (81.1%). The types of OF were vesico-vaginal fistula (VVF) (62.2%), urethro-vaginal fistula (24.3%), vesico-uterine fistula (VUF) (5.4%), and uretero-vaginal fistula (2.7%). The fistula site was supra trigonal (54.1%), urethral (18.9%), trigonal (10.8%), vesico-uterine (10.8%), cervical urethral (2.7%), ureteroid vaginal (2.7%). Fistulas were complex (70.3%), complicated (24.3%) and simple (5.4%). The vaginal route was one of the first routes (64.9%). The operative techniques used were CHASSAR MOIR hysterorrhaphy (74.3%). The cure with continence was 68.6%. Conclusion: OF is observed in young women of childbearing age. VVF is the most common. The management is surgical with several operating techniques. Healing is possible. Hence the importance of paying special attention to these patients for their care.
文摘The research reported in this paper investigated the role of identity construction in the emergence and escalation of conflict in the participatory management of protected areas in Benin. The study shows that social identity salience was dynamic and played an important role in the emergence and escalation of conflict in the studied cases. Conflicts emerged when identities became salient as a result of the stake-holders’ framing of contextual factors as a threat to their identity. The conflicts escalated when decisions and actions undertaken in the management process were framed as top-down and as posing a threat to the identities of the stakeholders. We conclude that, although the government in the management of the protected areas introduced participation, unilateral decisions taken about the way the conflicts should be managed caused disappointment and distrust, and thus led to a greater distance between the parties involved and to conflict escalation.
文摘Soils degradation is one of the constraints in food security achievement in Benin. This study aimed at assessing the effect of cropping systems and slope on soil physical and chemical properties in the watershed of Kpacomey located in the Aplahoué district. Soil samples were collected from three parallel transects along the slope. Sampling was carried out under different treatments combining cropping systems (Maize-Cassava, pure Palm grove, Palm grove-Maize-Cassava and Teak Plantation) along with slope levels (low slope, medium slope and high slope degree). The impact of cropping systems and slope on soil properties was assessed by determining the physical and chemical parameters. The cropping systems significantly (p < 0.05) influenced soil bulk density, root biomass, soil acidity and soil organic matter. The lowest soil bulk density (1.38 g/cm<sup>3</sup>) was recorded under the Palm grove-Maize-Cassava cropping system while the highest (1.47 g/cm<sup>3</sup>) was obtained with pure Palm grove cropping system. Root biomass was more abundant (0.28%) with the pure Palm grove cropping system. However, root biomass was significantly (p < 0.05) influenced by slope. Soil crusting resulted in no significant influence (p > 0.05) on the effect of cropping systems and slope. Moreover, cropping systems resulted in significant effects (p < 0.05). Soil organic matter and soil-assimilated phosphorus content were significantly influenced by the effect of the slope. These findings indicated that cropping systems and slope are significant drivers in soil degradation in the Kpacomey watershed and bringing out cropping systems that best aim at soil conservation.
文摘The better knowledge of a plant genetic biodiversity is based on a prior study of its agro-morphological characteristics. The objective of this study was to investigate the morphological diversity of maize accessions and its structure on the basis of 14 variables. For the experimentation, 43 and 98 maize accessions were planted in three replicates respectively in central and northern Benin following an incomplete randomized block. The mixed model analysis of two factors variance revealed a significant difference for all accessions considering each agro-morphological characteristic evaluated except the germination day of two areas seed accessions. The numerical classification grouped the accessions into four groups in each zone. The stepwise discriminant analysis showed that early characters related to plant height and ear insertion were the variables that discriminated accessions in both zones. Maturity and recovery ears, sensitivity to streak and the germination days are the variables that discriminate accessions of the two areas. These results provide a database for the creation of improved maize varieties that meet the needs of
文摘The protection of aquatic ecosystems is of great importance to maintain the biological balance necessary to secure healthy foods therein imbedded. Toho Lake, located to the south east of Benin, is threatened by pollution emanating from anthropogenic activities with the use of chemical fertilizers, effluent of domestic waste, particularly human and animal excrement with neighbourhood effluents. This study aimed at assessing some heavy metals in fresh fish (Oreochromis aureus) of Toho Lake in order to secure healthy food for the population and protect the ecosystem. Samples of water and fishes were collected and analyzed by HACH DR 3900 after treatment. Results revealed a mean oxygenation of water (4.95 mgo2/l), Biochemical Oxygen Demand (21.5 mgo2/l), Chemical oxygen Demand (149, 39 mg/l) with the nitrogen in Nitrate (NO3: 0.18 mg/l), ammonium nitrate (N-N: 0.47 mg/l), and phosphorous (2.06 mg/l) to be very high. The highest contents of heavy metals obtained in the fresh fish were cadmium (32.25 mg/kg), copper (115 mg/kg), lead (8.25 mg/kg), and zinc (90.75 mg/kg) and revealed that the fishes of Toho lake were polluted. The finding allowed us to conclude that the pollution of the lake and the fish carnage are due to anthropogenic pollution through chemicals spilling. Some protection methods of the lake and ecosystem are proposed in order to keep the fish safe and protect the well-being of the population.
文摘Introduction: Vitamin D’s action outside of bone, especially on immunity, is widely reported in the international scientific literature over the last years. Objective: Calculate the frequency of hypovitaminosis D in children aged 6 to 59 months suffering from severe malaria in the CHUD-P pediatric unit in 2016. Setting and Methods: This research work is a cross-sectional study with descriptive and analytical purposes. Data gathering was prospective. The study involved children aged 6 to 59 months hospitalized for severe malaria in the CHUD-P pediatric unit. The said children were HIV-uninfected, eutrophic and had not received vitamin D supplementation during the last 6 months. Vitamin D dose was measured using the High Performance Liquid Chromatography (HPLC) technique. Results: A total of 80 subjects were involved in the survey. Mean age was 26.08 months, sex ratio was 0.8 and average weight was 10.80 kg. Hypovitaminosis D frequency was 83.8% (67 cases out of 80 children investigated during the survey) with an average plasma concentration of vitamin D estimated at 21.57 ng/ml ± 7.34 with two extremes (11.24 - 42.32) ng/ml. The minimum parasitaemia was 202 P/μl and the maximum was 580,000 P/μl. Conclusion: Hypovitaminosis D is common in children suffering from severe malaria;this result suggests conducting a large-scale community-based study to decide on vitamin D inclusion in national supplementation policies and severe malaria management.
文摘Background: Couple High Blood Pressure (HBP)-Diabetes is a morbid association and a public health problem. The aim of this study was to determine the actual epidemiological profile of HBP in type 2 diabetic. Methods: A cross-sectional, prospective, descriptive and analytical study was conducted at Banque d’insuline of Cotonou, Polyclinique Atinkanmey and CHUD-Ouémé-Plateau. The study took place over a period of 06 months from March 01 to August 30, 2014. The study included patients with type 2 diabetes mellitus seen at consultation who agreed to participate in the study. Results: The survey involved 400 individuals. Among them, 34% were male and the sex ratio was 0.48. The mean age was 55.6 ± 10.3 years (range 28 - 87 years). The prevalence of hypertension in type 2 diabetic patients was 70%. The risk factors significantly associated with HBP were age above 55 years (p = 0.000), abdominal obesity (p = 0.036), a diabetes duration above 10 years (p = 0.009). Complications significantly associated with HBP were stroke (p = 0.013) and diabetic foot (p = 0.044). Conclusion: HBP-type 2 Diabetes association is frequent in Benin.
文摘Objective: To study the epidemiological and diagnostic aspects of urogenital trauma at the Borgou University and Departmental Hospital Center. Material and Methods: This was a descriptive cross-sectional study that took place over a period of 4 years and 4 months (52 months) from January 1<sup>st</sup> 2017 to April 30<sup>th</sup> 2021. All cases of urogenital trauma treated in the General surgery department during the period were collected. Patient records, hospitalization registers and operating reports were used to collect information. Data entry was done using Epi data 3.1 software, French version. The analysis was performed using MedCalc software (version 19.4.1. Mariakerke, Belgium), and Epi info software version 7. Results: In 52 months, 75 cases of urogenital trauma were collected. The prevalence of urogenital trauma was 1.1% of admissions with an annual incidence of 17.3 cases. The modal age class was [20;40], i.e. 49.3%. Males accounted for 76.0% (n = 57) of cases. Urethral and kidney injuries were found in 33.3% and 21.3%, respectively. The external genitalia was involved in 24.0%. Road traffic accidents occupied the first place with 62.6%. Kidney lesions were revealed by lumbar pain in 62.5% (n = 10) and post traumatic hematuria in 25% (n = 4) of cases. Most of the patients (n = 8, i.e. 50%) were classified as grade I according to the AAST classification. Conclusion: Urogenital trauma is common in our environment and can be life-threatening. Knowledge of their epidemiology will allow for prevention and good management.
文摘Climate change and population growth have led to the increase and/or intensification of flooding becoming a major issue. The objective of this study is to visualize flooding risk of municipalities at the intersection of the coastal sedimentary zone and the crystalline surface. The methodology adopted is based on geomatic approach, which involves documentary research, processing and assisted classification using remote sensing images and multi-criteria analysis of the Geographic Information System (GIS). Flooding risk is very high at 8.85% in Djidja, Toffo, Zè and Bonou municipalities. In other municipalities such as Agbangnizoun, Abomey, Bohicon, Za-Kpota and Cove, it is high of 46.85%. To the Southeast of the study area, it is located on the eastern and western banks of Oueme Valley. The medium risk represents 26.35% and is located in the municipalities of Ouinhi and Adjohoun. The other municipalities have a low rate of 17.95%. Risk modeling has made it possible to access the various levels of rising water that can cause flooding. Land-use planning decisions can be influenced by the results of this study.
文摘The application of biostimulants in agriculture represents an environmentally friendly alternative while increasing agricultural production. The aims of the study were to develop solid biostimulants based on five rhizobacteria native to Benin’s soils and to evaluate their efficacy on the growth and biomass yield of maize under greenhouse conditions on ferrallitic and ferruginous soils. Clay and peat were used as a conservation binder for the preparation of the biostimulants. These binders were used alone or combined in the different formulations with maize flour and sucrose. 10 g of biostimulants were applied at sowing in pots containing five kilograms of sterilised soil. The experimental design was a completely randomised block of 24 treatments with three replicates. The results obtained showed significant improvements (<em>P</em> < 0.001) in height (49.49%), stem diameter (32.7%), leaf area (66.10%), above-ground biomass (97.12%) and below-ground biomass (53.98%) on ferrallitic soil with the application of the clay + <em>Pseudomonas putida</em> biostimulant compared to the control. On the other hand, the use of the peat biostimulant + <em>Pseudomonas syringae</em> was more beneficial for plant growth on ferruginous soil. The height, stem diameter, leaf area, above-ground biomass and below-ground biomass of the plants under the influence of this biostimulant were improved by 83.06%, 44.57%, 102.94%, 86.84% and 42.68%, respectively, compared to the control. Therefore, these results confirm that Rhizobacteria express their potential through biostimulants formulated on maize. The formulated biostimulants can later be used by producers to improve crop productivity for sustainable agriculture.

文摘Cholera is re-emerging as an infectious disease with an increase in its overall incidence in Africa since 2008. To analyze the epidemiological aspects of the cholera outbreak in endemic areas in Benin. The study is a retrospective investigation on 2560 data of cholera patients received in health facilities from 2012 to 2016 in Benin. Besides, a prospective study was conducted. This prospective study includes 513 person (health professionals, community workers and people exposed to cholera) of five different areas of the country. It was conducted from April 10 to May 10, 2017. A survey was conducted over 513 in order to collect data on cholera symptoms, hygiene guidelines suggested by the respondents, excreta disposal, drinking water, household waste management and direct observation. Software R 3.4.0 was used for simple correspondence factor analysis (CFA). From 2012 to 2016, 16.48% of samples were taken and 48.34% were positive for <i>Vibrio cholera</i> O1, <i>El Tor biotype</i>, <i>Ogawa serotypes</i>. The Littoral area is leading in the number of cases (33.83%) followed by Atlantic (23.75%), Ouémé (16.79%) and Colline (8.91%). The survey revealed that the exposed populations are unaware of the symptoms of cholera and do not perceive the quality of drinking water as a strong guidance in the prevention of cholera. Nevertheless, the majority of respondents (86%) are aware for the best times to wash their hands and know that they need to go to hospital in case of symptoms. Our study highlights the persistence of vulnerability factors to cholera in the targeted population, despite a good knowledge of prevention rules among staff and the population.
