Methods: PCR was executed on DNA extracted from 77 tick pools to detect Anaplasma phagocytophilum, Bartonella spp., Borrelia burgdorferi sensu lato, Coxiella burnetii and Rickettsia spp. Results: A total of 432 ticks were collected: 30(6.94%) Haemaphysalis punctata, 72(16.7%) Dermacentor marginatus and 330(76.38%) Ixodes ricinus. For each animal one or two pools of 3 ticks of the same species was constituted. Seventy-seven tick pools were examined by PCR: 58(75.32%) resulted infected and among them 14(18.18%) showed co-infections. In particular, 29(37.66%) pools were positive for Bartonella spp., 23(29.87%) for Anaplasma phagocytophilum, 16(20.78%) for Rickettsia spp., and 5(6.49%) for Borrelia burgdorferi s.l. All samples were negative for Coxiella burnetii. Conclusions: The results demonstrate the presence of several zoonotic tick-borne pathogens in the studied area, and underline the risk of exposure to infections for hunters not only during the outdoor activity, but also when they manipulate hunted animals infested by infected ticks.展开更多

Wild animals in zoological gardens can predominately affected by various gastro-intestinal parasites. This study was therefore, conducted to determine occurrence, identify types and assess seasonal variation of gastrointestinal parasites in captive animals at the Zoological garden of Haramaya University. The study involved a retrospective investigation of zoo records and fecal examinations. Twenty two fecal samples were collected in December, 2013 from all the animals in the garden and examined using concentration and fecal culture techniques. Sampling was repeated after four months in April, 2014 to assess seasonal variations of the parasites. The result from the retrospective study showed death of 21 animals in the last five years. Fecal examination confirmed presence of gastrointestinal parasites with an overall mean prevalence rate of 73.8%. A total of 9 parasite taxa were identified of which 6 (66.67%) and 4 (33.33%) were helminths and protozoa respectively. No Cestode and Trematode species were recovered. <i>Trichuris spp.</i>, <i>Toxocara spp.</i>, <i>Strongyloides spp.</i>, <i>Toxascaris leonine</i>, <i>Passalurus ambiguous</i> and <i>Ascaridia spp.</i> were the helminth parasites observed in the garden. <i>Entamoeba spp.</i>, <i>Isospora spp.</i> and <i>Eimeria spp.</i> were the protozoan parasites encountered. No remarkable seasonal variation in parasitic infection was noticed in the garden. The study revealed occurrence of gastrointestinal parasites in the zoological garden, most of which are zoonotic and hence future studies are needed to determine risks of cross-transmission.展开更多

However, existin, approaches to combat food insecurity shock have generally focused on reducing vulnerability via increasing productivity of domesticated foods. In contrast, approaches that enhance resilience mainly through wild fooc sources have been less focused. This study examined the contribution of wild foods to household resilience to food insecurity in the green famine belt of Ethiopia. Methods： A cross-sectional survey of 220 households was conducted using a structured questionnaire, key informant interviews, and semi-participant observations. Factor analysis was run using SPSS to analyze data. Correlation analysis was used to examine the direction and strength of association between wild foods and the income and food access （IFA）, a latent proxy indicator of resilience. Cross-tabulation was also run to determine the proportion of households in each ethno〈ulture group under each resilience category. Results： The mean amount of wild foods obtained by households was 156.61 kg per household per annum. This was about 5 % and 9 % of, gross and, net food available from all sources respectively. Wild foods contributed well to household resilience as the factor loading （Factor2 = 0.467） was large enough and were significantly correlated with IFA （r-- 0.174）. Wild vegetables were the most collected and consumed type of wild foods constituting 52.4 % of total amount of wild foods. The total amount of wild foods was smaller than that of domesticated sources of food. The majority of households （38.6 %） reported ＂reduced source of wild foods＂ as a reason for this. Smaller proportion of the indigenous （11.2 %） than the non-indigenous （34.1%） ethno-culture group reported one or more reasons for their lower level of dependence on wild foods. Conclusion： From the study we concluded that wild foods had important contribution to households＇ resilience to food shortages and are likely to continue to contribute in the future, this being more to indigenous than non-indigenous ethno-culture group. Therefore, a resilience building policy that incorporates wild foods should be adopted, and research that aims at exploring their current status and future prospect are urgently required.展开更多

To enable diagnosis in such cases, there is a need for a reliable method, using an alternative non-neural tissue, which can be removed and submitted to the diagnostic laboratory without special training or equipment. In human medicine, skin is used successfully for the detection of rabies virus antigen using RT-PCR technology. Little work has been done in animals using RT-PCR on skin or extracted hair follicles. The current study was conducted in Grenada on skin from 36 wild and domestic animals, in which rabies virus infection had been confirmed in brain tissue via the direct fluorescent antibody (DFA) test, and in 31 negative control animals. RT-PCR on skin yielded a sensitivity of 97.2% (35/36) and a specificity of 100% (31/31). It is concluded that the examination of skin samples via RT-PCR provides a valuable diagnostic alternative in those cases where brain tissue is not readily available.展开更多

文摘The informal term‘dahongjun’or‘big red mushroom’is a group of red-coloured russulas widely collected and consumed in southern China,originally mistakenly recognized as the European Russula vinosa.Russula griseocarnosa was described from China in 2009,and since then,it has become the only available scientific name for‘dahongjun’.Nevertheless,several lineages exist within this complex,and whether these lineages represent real species is still an open question.Sampling in major producing areas of‘dahongjun’and phylogenetic species recognition using multi-locus data were conducted.Besides R.griseocarnosa nine additional species were identified under the commercial name‘dahongjun’,including R.dhakuriana,R.quercina,R.purpureozonata,R.yanheensis and a new species sister to R.griseocarnosa here described as R.occulta.The others were undescribed species close to R.laricina,R.lepida,and R.purpureozonata respectively.Six evolutionary lineages within R.griseocarnosa were defined by genealogical concordance phylogenetic species recognition based on five-locus DNA data.Conflicts among different genealogies suggested that R.griseocarnosa is best considered as a single phylogenetic species,comprising several infraspecific taxa.Lower coverage whole genome sequencing of R.griseocarnosa holotype discovered that its three individuals belong to three different clades.Lectotypification was made using one of the three individuals.A new variety R.griseocarnosa var.ailaoshanensis is described to name one of the terminal clades that is mainly distributed in Ailao Mountains.This variety differs morphologically from the type variety in its nearly white context,bigger spores and more inflated hyphae in the pileipellis.The morphological and molecular data provided in this study are helpful to identify wild edible mushrooms of Russula subgen.Russula.

文摘Bread wheat(Triticum aestivum L.)is a staple hexaploid crop with numerous wild relatives.However,domestication and modern breeding have significantly narrowed its genetic diversity,diminishing its capacity to adapt to climate change.Wild relatives of wheat serve as a vital reservoir of genetic diversity,offering traits thatenhance its resistance to various biotic and abiotic stresses.Over recent decades,remarkable progress has been made in utilizing superior genes from wild relatives to bolster wheat's defenses against diseases and pests,though the exploration of genes conferring abiotic stress tolerance has lagged behind.In this review,we summarize key advancements in the utilization of wild relatives for wheat enhancement over the past century,emphasizing both theoretical and technological innovations.Furthermore,we evaluate the potential contributions of wild relatives to address production challenges posed by climate change.We also explore strategies for isolating superior genes and developing prebreeding germplasm to support the future development of climate-resilient wheat varieties.

文摘This study examines how foreign language education in the artificial intelligence(AI)era could assist the cultivation of national consciousness through a technology-enhanced pedagogy of film appreciation.Using The Wild Robot as a case study,we argue that cinematic narratives serve as cultural mirrors,offering immersive,reflective,and affective sites for intercultural learning.We propose a three-layered pedagogical framework-progressing from semiotic decoding,through narrative and value comparison,to creative identity construction-that integrates intelligent tools to develop both communicative competence and an agentive sense of belonging.The approach exemplifies a humanistic turn in language teaching,aiming to form“rooted global communicators”who can engage in cross-civilization dialogue with cultural confidence and critical awareness.
文摘[Objectives]To provide a reference for the efficient use of wild Paeonia suffruticosa germplasm resources and the scientific selection of parents.[Methods]This study systematically evaluated cross-compatibility by conducting interspecific crosses among the major wild species subsect.Delavayanae(Paeonia delavayi,Paeonia lutea,Paeonia potaninii,and Paeonia ludlowii)as well as reciprocal crosses between these species and cultivated varieties from the subsect.Vaginatae.[Results]Crosses among P.delavayi,P.lutea,and P.potaninii generally exhibited good seed set,with the resulting seeds showing a high emergence rate.In contrast,crosses involving P.ludlowii as a parent produced only a limited number of seeds,none of which germinated.In crosses with cultivated varieties where the wild species served as the maternal parent,the average seed set ranked as follows:P.lutea>P.delavayi>P.ludlowii>P.potaninii.When wild species were used as paternal parent,the average seed set ranked as follows:P.potaninii>P.lutea>P.delavayi>P.ludlowii.On the whole,most crosses between wild species of subsect.Delavayanae and cultivated varieties achieved normal seed set,demonstrating a certain degree of cross-compatibility.However,when the wild species served as the maternal parent,both the seed set and seedling emergence rate were superior to those in the reciprocal crosses(with wild species as the paternal parent).[Conclusions]Significant differences in cross-compatibility were observed among species within Paeonia subsect.Delavayanae.In addition,a significant maternal effect was identified in crosses between wild species of this subsection and cultivated varieties.These findings suggest that by selecting highly compatible combinations,there remains considerable potential for utilizing these wild species in peony breeding.

文摘Dear Editor,The highly pathogenic avian influenza viruses(HPAIVs)are important epizootic and zoonotic pathogens that cause significant economic losses to the poultry industry and pose a serious risk to veterinary and public health.Wild birds have been recognized as the primary reservoirs for influenza A virus,and some species show little sign of clinical disease or even can be asymptomatic during long distance carriers of the virus(Lycett et al.,2019).Since it was first discovered in 1959,the H5Nx HPAIVs have spread globally and cause outbreaks in wild birds,poultry and sporadic human and other mammalian infections(Lycett et al.,2019).Due to the reassortant events of diverse strains facilitated by migratory waterfowl,the clade 2.3.4.4 of H5Nx viruses acquiring neuraminidase(NA)gene from other low pathogenicity avian influenza viruses(LPAIVs)emerged in 2014 and gradually became the dominant sub-clade(Lee et al.,2017).
