METHODS: The databases including Medline, Embase, the Cochrane Library, Web of Science and Chinese Biomedicine Database were searched for all relevant randomized controlled trials that studied the effects of pre-, pro- or synbiotics in patients with acute pancreatitis. Main outcome measures were postoperative infections, pancreatic infections, multiple organ failure (MOF), systemic inflammatory response syndrome (SIRS), length of hospital stay, antibiotic therapy and mortality. RESULTS: Seven randomized studies with 559 acute pancreatic patients were included. Pre-, pro-or synbiot-ics treatment showed no influence on the incidence of postoperative infections [odds ratios (OR) 0.30, 95% conf idence interval (CI): 0.09-1.02, P = 0.05], pancre- atic infection (OR 0.50, 95% CI: 0.12-2.17, P = 0.36), MOF (OR 0.88, 95% CI: 0.35-2.21, P = 0.79) and SIRS (OR 0.78, 95% CI: 0.20-2.98, P = 0.71). There were also no signif icant differences in the length of antibiotic therapy (OR 0.75, 95% CI: 0.50-1.14, P = 0.18) and the mortality (OR 0.75, 95% CI: 0.25-2.24, P = 0.61). However, Pre-, pro-or synbiotics treatment was associ- ated with a reduced length of hospital stay (OR -3.87, 95% CI: -6.20 to -1.54, P = 0.001). When stratifying for the severity of acute pancreatitis, the main results were similar. CONCLUSION: Pre-, pro-or synbiotics treatment shows no significant influence on patients with acute pancreatitis. There is a lack of evidence to support the use of probiotics/synbiotics in this area.展开更多

METHODS: Forty-eight SD rats weighing about 280 g were used in this study. Rats were divided into three groups according to the contents of probiotics and prebiotics mixture in the feed as control, low and high dose groups. The duration of the experiment was 8 wk. RESULTS: Compared with the control group, thefecal Lactobacillus and Bifidobacterium counts were significantly increased and the fecal Coliform organism counts were markedly reduced in the low and high dose groups. Concerning the digestive enzyme activity of jejunum, only lactase activity increased in low dose group. However, significant increase of lipase, lactase, sucrase, and isomaltase activities were observed in high dose group.CONCLUSION: Intake of low and high dosages of probiotics and prebiotics mixture significantly improved the ecosystem of the intestinal tract by increasing the probiotics population and digestive enzyme activities in rats.展开更多

The aim of study was to determine influence of the in ovo stimulation, on d12 of incubation, with synbiotics（synbiotic 1-L. salivarius IBB3154 ＋ Bi^2tos, Clasado Ltd. and the synbiotic 2-L. plantarum IBB3036 ＋ lupin RFOs） on the microstructure of duodenum, jejunum and ileum in the 1^（st） and 42^（nd）day of rearing.Results： On the 1^（st） day of chickens life, in the duodenum of both experimental groups（SYN1 and SYN2）, a significantly higher and wider intestinal vil i as wel as a significantly larger absorbent surface of these villi were found in comparison with the Control group（P ≤ 0.01）. On the 42^（nd）day of rearing the beneficial effect of synbiotic 1 was reflected by the numerical y higher vil i（no statistical differences） with a larger surface（P ≤ 0.01） in the duodenum in the SYN1 group compare to the Control group. In the jejunum on the 1^（st） day of life, in the SYN1 group, significantly higher vil i than in the Control group, with a simultaneous decrease in the depth of crypts（P ≤ 0.01）, and also the largest width of vil i and their absorbent area（P ≤ 0.01） in comparison to the other groups were found. On the 42^（nd）day of life, in the jejunum, an increase in the height of the vil i whilst reducing the crypt depth in the SYN2 group was found（P ≤ 0.01）. In turn, in the SYN1 group, there were significantly more neutral goblet cel s observed compared with the control group（P ≤ 0.05）. In the ileum of 1-day-old chickens, the widest vil i（P ≤ 0.05） and the deepest crypts（P ≤ 0.01） were found in the SYN2 group. In the same group, there was also the least amount of neutral goblet cel s in comparison to the other groups（P ≤ 0.05）.Conclusions： We observed that synbiotic 1 and 2 beneficial y affected the examined characteristics on the 1^（st） and 42^（nd） day of life. The obtained results al ow us to conclude that the use of synbiotics significantly affect gut structure which should contribute to improvement in nutrient absorption by the gut.展开更多

The supplementation of probiotics and synbiotic could indeed manipulate the microflora, which can be an alternative therapy for ulcerative colitis, and Crohn's disease. Several in vitro, in vivo and clinical studies for the initiation and maintenance of remission in patients with inflammatory bowel disease have been completed.Those studies evaluated the efficacy of many probiotic formulations, especially about VSL#3.Even though the clinical studies proved that almost all the probiotic interventions are safe and bring improvement to patients, some studies are deficient in sample size, proper controls, and follow-ups. This paper summarizes the possible mechanism of inflammatory bowel disease development, probiotics, the clinical outcome of probiotic and synbiotic interventions for ulcerative colitis and Crohn's disease, as well as the adverse effect of probiotic treatments.展开更多

Totally 216 individuals of 35-day-old piglets were randomly divided into three groups, six replicates for each group, and each replicate contained 12 piglets. The first group was antibiotics group, 20 g,/t colistin sulfate （active ingredients） were added in the basal diet; the second group was synbiotics group, 250 g/t synbiotics （contai- ning xylooligesaccharides, oligochitasan, Bacillus subtilis and Clostridium butyricum） were added in the basal diet; the third group was combination group, 20 g/t colistin sulfate and 250 g/t synbiotics were added in the basal diet. The whole trial lasted 28 d. The results showed that there was no difference between synbiotics group and antibiotic group in growth performance, nutrients digestibility or antioxidant indicators （ P 〉 0.05 ）. Compared with the piglets in synbiotics group and an- tibiotic group, piglets in combination group had higher digestibility of dry matter and organic matter, and higher T-SOD activity in serum （ P 〈 0.05 ）. It is conclu- ded that synbiotics can replace antibiotics for piglets at 35 -63 days of age. Synbiotics and antibiotic had the synergistic effect on nutrient digestibility and antioxi- dant function of piglets.展开更多

In this background, the food source in both animal and plant origin must be increased accordingly. For these we must use and add some feed additives such as antibiotic, probiotic, prebiotic, postbiotic and synbiotic for the animal feed to increase production (meat, egg, milk and fish) and improve health. In early cases, probiotic as mono or mixed beneficial live microorganism was used as feed additive that plays a significant role in several health conditions and performances. In another way, the scientists use some ingredients indigestible with carbohydrates origin, especially oligosaccharides as a source of energy for beneficial microorganisms in the body which were called prebiotic, and it is indigestible fermented food substrates that stimulate the growth, composition and activity of microorganisms in gastrointestinal and improve host. Most of the scientists urged to use all the above in such way that have more benefits in animal health and performance which were therefore called synbiotic, that was a combination between probiotic and prebiotic which beneficially had significant effects on the host by improving the survival and implantation of live microbial dietary supplements in the gastrointestinal tract, and thus improving animal health and performance. So, it was proposed that the synbiotic in this research increased beneficial microorganisms in the gastrointestinal tract and improved intestinal architect, and then promoted intestine environment. Consequently, it can improve blood indices, and especially decrease bad cholesterol (Low-density lipoprotein), decrease harmful microorganisms and toxins. However, it can also improve ingredient product, increase mineral absorption and nutrient. In conclusion, it can improve animal health and performance.展开更多

After 42 d animals were slaughtered. Blood serum, pancreas, duodenum and duodenum content were collected.Results: Syn2 increased trypsin activity by 2.5-fold in the pancreas and 1.5-fold in the duodenal content. In the duodenum content, Syn2 resulted in ca 30% elevation in lipase activity and 70% reduction in amylase activity.Syn1 and Syn2 strongly decreased expression of m RNA for GLP-1 and GIP in the duodenum and for GLP-1 receptors in the pancreas. Simultaneously, concentrations of the incretins significantly diminished in the blood serum(P < 0.05). The decreased expression of incretins coincides with changed activity of digestive enzymes in the pancreas and in the duodenal content. The results indicate that incretins are involved in the action of Syn1 and Syn2 or that they may even be their target. No changes were observed in key hormones regulating metabolism(insulin, glucagon, corticosterone, thyroid hormones, and leptin) or in metabolic indices(glucose,NEFA, triglycerides, cholesterol). Additionally, synbiotics did not cause significant changes in the activities of alanine and aspartate aminotransferases in broiler chickens. Simultaneously, the activity of alkaline phosphatase and gamma glutamyl transferase diminished after Syn2 and Syn1, respectively.Conclusion: The selected synbiotics may be used as in ovo additives for broiler chickens, and Syn2 seems to improve their potential digestive proteolytic and lipolytic ability. Our results suggest that synbiotics can be directly or indirectly involved in incretin secretion and reception.展开更多

Incidence of C. difficile infection ...Infection by Clostridium difficile, a complication of treatment with antibiotics, causes antibiotic- associated diarrhea (AAD) and can lead to colitis and pseudomembranous colitis. Incidence of C. difficile infection is increasing among the elderly undergoing antibiotics therapy confined to health care facilities, conditions that are expensive to treat, decrease the quality of life and are life threatening. Use of probiotics has been proposed as a method to decrease the incidence of AAD in health care facilities. To examine the efficacy of using probiotics, 120 nursing home residents undergoing antibiotic therapy were provided with a synbiotic tablet containing two probiotics, Saccharomyces boulardii and Bacillus coagulans, and a prebiotic, fructooligosaccharide. Residents were evaluated retrospectively for AAD and C. difficile infection. It was found that 95% of residents treated with antibiotics and taking the synbiotic tablet were free of AAD. More than 97% of the residents did not become infected with C. difficile. No adverse effects were reported. Minor side effects, gastrointestinal upset and nausea, were reported by less than 6% of the residents. The cause of the minor side effects was not known. Only 2.5% of the residents stopped taking the synbiotic tablet because of the gastrointestinal upset. These Results suggest that use of the synbiotic tablet prevents AAD and C. difficile infection in nursing home residents undergoing antibiotic therapy. It is concluded that this synbiotic tablet provides an easy to administer and safe approach to controlling AAD and C. difficile infection in residents in nursing homes.展开更多

Thus, different products have been designed to meet this demand, especially those with probiotic and prebiotic characteristics. This study aimed to evaluate different formulations of a soy-based synbiotic beverage. The composition and process conditions were defined using a Placket & Burman factorial design in which the independent variables were process temperature, concentrations of the soy hydrosoluble extract and fructooligosaccharides (FOS) and the initial concentration of the probiotics Bifidobaterium longum, Lactobacillus acidophilus, Lactobacillus paracasei subsp. Paracasei, Lactobacillus rhamnosus. Changes to the product by addition of sucrose, Streptococcus thermophilus and Lactobacillus delbrueckii subsp. Bulgaricus were also studied. Response parameters were: pH, cell concentration (plate counting), and quantification of fructooligosaccharides, acetic acid and lactic acid. The specific growth rate (μx) and change in cell count (Δx) were determined in each formulation. The soybean hydrosoluble extract was considered a good substrate for beverage production;FOS had a greater effect at lower concentrations. At the end of all fermentation tests the total probiotic count was greater than 7 log CFU/mL, meeting the legal requirements of a functional food. Lower temperatures were better for the growth of probiotics. The addition of sucrose resulted in a lower consumption of FOS by the fermenting microorganisms, while the presence of Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus represented little change concerning the evaluated characteristics. Therefore, according to the results of this study, the production of a soy-based symbiotic fermented beverage can be performed using soybean hydrosoluble extract at 10% (w/v), fructooligosaccharides at about 3% (w/v), sucrose at 12% (w/v), and the process temperature should be maintained at 35℃. Initial probiotic concentrations need not exceed 5 × 106 CFU/ml.展开更多

Probiotics can improve immune system functions via different mechanisms. We proposed that Synbiotic Lactocare<span style="white-space:nowrap;"><sup><span style="white-space:nowrap;"><span style="white-space:nowrap;">?</span></span></sup></span> may also reduce SARS-Cov2 infection in high-risk medical staff working in COVID-19 hospital wards. <strong>Method:</strong> In a randomized, controlled trial, 60 hospital staff without any history of clinical or laboratory evidence of SARS-Cov2 infection were received either once-daily oral synbiotic capsule (Lactocare<span style="font-size:10px;"><sup><span style="white-space:nowrap;"><span style="white-space:nowrap;">?</span></span></sup></span>) that contains 1 billion CFU/Cap of L. (Lactobacillus) casei, <em>L. rhamnosus</em>, <em>Streptococcus thermophilus</em>, <em>Bifidobacterium breve</em>, <em>L. acidophilus</em>, <em>Bifidobacterium infantis</em>, <em>L. bulgaricus</em>, and Fructooligosacharide (Zist Takhmir, Tehran, Iran) or placebo with the same appearance for 30 days. They were followed for two months. <strong>Result:</strong> During the two-month period of this study, SARS-COV-2 RT-PCR test results were positive in three participants (9.67%) in placebo group compared to zero positive tests in synbiotic group. The differences were not statistically significant (p = 0.238). During the study, two persons (7 %) of placebo group had respiratory complaints such as cough, rhinorrhea and/or dyspnea, compared with one in synbiotic group (p = 0.492). <strong>Conclusion:</strong> This study showed that overall frequency of SARS-COV2 infection in participants receiving synbiotic and those receiving placebo did not differ significantly. However, 3 hospital staff in placebo group compared to no one in synbiotic group had SARS-COV2 infection. Further studies with greater power and alternative probiotic strains and mixture are warranted to determine whether Synbiotic can prevent COVID-19 in at-risk hospital staff.展开更多

文摘Probiotics show anti-influenza activity,offering a potential variant-resistant alternative for infection prevention and control.In this study,we evaluated whether a specially formulated yogurt enriched with synbiotics(named yogurt 1)with 7 probiotics and 6 prebiotics,has anti-influenza effects and its underlying mechanisms using a mouse model challenged with influenza virus H1N1 PR8 strain.The mice were treated with phosphate-buffered saline(negative control),yogurt matrix,yogurt 1,and oseltamivir(positive control),respectively.Yogurt 1 treatment improved the survival of infected mice(from 0%to 30%),alleviated pathological injuries in the lungs and colon,and reduced the viral load of influenza virus on day 3 and day 7 post-infection.Yogurt 1 also downregulated some inflammation-related signaling pathways and reduced the levels of proinflammatory cytokines or chemokines in the lungs or serum,including interleukin(IL)-1β,IL-6,tumor necrosis factor-α(TNF-α)and keratinocyte chemoattractant(KC).The levels of short-chain fatty acids in the cecal content were increased,the diversity of the intestinal flora was partially restored,and influenza-specific Ig G and interferon-secreting lymphocytes were enhanced following yogurt 1 administration.Thus,yogurt 1,as a commercial and easily accessible dairy product,demonstrated a notable anti-influenza effect in mice by inhibiting viral proliferation,suppressing excessive inflammatory responses,and promoting influenza virus-specific adaptive humoral and cellular immune responses,demonstrating its potential for influenza epidemic prevention and control.

文摘The oyster mushroom(Pleurotus spp.)is one of the most widely cultivated mushroom species globally.The present study investigated the effect of synbiotics on the growth and quality of Pleurotus ostreatus and Pleurotus pulmonarius.Different synbiotics formulations were applied by spraying mushroom samples daily and measuring their growth parameters,yield,biological efficiency,proximate composition,mineral content,total phenolic content(TPC),and diphenyl-1-picryl-hydrazyl(DPPH)radical scavenging activity.Results demonstrated that the most significant yield of oyster mushrooms was harvested from synbiotics sprayed with inulin and Lactobacillus casei(56.92 g).Likewise,the highest biological efficiency obtained with a similar synbiotic was 12.65%.Combining inulin and L.casei was the most effective method of improving the mushrooms'growth performance and nutrient content in both samples.Furthermore,synbiotics that combined inulin and L.casei resulted in the highest TPC(20.550 mg gallic acid equivalent(GAE)/g dry extract(DE))in white oyster mushrooms(P.ostreatus).In comparison,in grey mushroom(P.pulmonarius)the highest TPC was yielded by L.casei(1.098 mg GAE/g DE)followed by inulin and L.casei(1.079 mg GAE/g DE).The DPPH results indicated that the oyster mushroom could be an efficient antioxidant.The results revealed that applying synbiotics improved the mushrooms'quality by increasing their antioxidant capacity with higher amounts of phenolic compounds and offering better health benefits with the increased levels of mineral elements.Together,these studies demonstrated the potential of using synbiotics as a biofertilizer,which is helpful for mushroom cultivation;therefore,it might solve the challenge of inconsistent quality mushroom growers face.

文摘Background Lactulose as an effective prebiotic protects intestinal mucosal injury.Bacillus coagulans is widely used in feed additives because of its ability to promote intestinal health.Our previous study suggests that the combination of lactulose and Bacillus coagulans may be a good candidate as alternative for antibiotic growth promoters.However,the in vivo effects of lactulose and Bacillus coagulans on growth and intestinal health under immune challenge in piglets remains unclear.The objective of this study is to explore the protective effects of synbiotic containing lactu-lose and Bacillus coagulans on the intestinal mucosal injury and barrier dysfunction under immune challenge in weaned piglets.Methods Twenty four weaned piglets were assigned to 4 groups.Piglets in the CON-_(saline)and LPS-_(LPS)group were fed the basal diet,while others were fed either with chlortetracycline(CTC)or synbiotic mixture of lactulose and Bacillus coagulans for 32 d before injection of saline or lipopolysaccharide(LPS).Piglets were sacrificed 4 h after LPS injection to collect samples to determine intestinal morphology,integrity and barrier functions as well as relative genes and proteins.Results Our data showed that no differences were observed in the growth performance of the four test groups.LPS injection induced higher serum diamine oxidase activities,D-lactic acid levels,and endotoxin status,lower villus height and ratio of villus height to crypt depth,greater mRNA and lower protein expression related tight junction in both jejunum and ileum.In addition,a higher apoptosis index,and protein expression of Bax and caspase-3 were also observed in the LPS challenge group.Interestingly,dietary synbiotic mixture with lactulose and Bacillus coagulans protected against LPS-induced intestinal damage,barrier dysfunction and higher apoptosis as well as CTC.Conclusions Our data suggest that dietary supplementation of synbiotic mixture with lactulose and Bacillus coagu-lans showed resilience to LPS-induced intestinal morphological damage,barrier dysfunction and aggressive apoptosis in piglets as well as the protective effects of CTC.These results indicate that synbiotic mixture of lactulose and Bacillus coagulans showed beneficial effects on performance and resilience to acute immune stress in weaned piglets.

文摘AIM: To assess the clinical outcomes of pre-, pro-and synbiotics therapy in patients with acute pancreatitis. METHODS: The databases including Medline, Embase, the Cochrane Library, Web of Science and Chinese Biomedicine Database were searched for all relevant randomized controlled trials that studied the effects of pre-, pro- or synbiotics in patients with acute pancreatitis. Main outcome measures were postoperative infections, pancreatic infections, multiple organ failure (MOF), systemic inflammatory response syndrome (SIRS), length of hospital stay, antibiotic therapy and mortality. RESULTS: Seven randomized studies with 559 acute pancreatic patients were included. Pre-, pro-or synbiot-ics treatment showed no influence on the incidence of postoperative infections [odds ratios (OR) 0.30, 95% conf idence interval (CI): 0.09-1.02, P = 0.05], pancre- atic infection (OR 0.50, 95% CI: 0.12-2.17, P = 0.36), MOF (OR 0.88, 95% CI: 0.35-2.21, P = 0.79) and SIRS (OR 0.78, 95% CI: 0.20-2.98, P = 0.71). There were also no signif icant differences in the length of antibiotic therapy (OR 0.75, 95% CI: 0.50-1.14, P = 0.18) and the mortality (OR 0.75, 95% CI: 0.25-2.24, P = 0.61). However, Pre-, pro-or synbiotics treatment was associ- ated with a reduced length of hospital stay (OR -3.87, 95% CI: -6.20 to -1.54, P = 0.001). When stratifying for the severity of acute pancreatitis, the main results were similar. CONCLUSION: Pre-, pro-or synbiotics treatment shows no significant influence on patients with acute pancreatitis. There is a lack of evidence to support the use of probiotics/synbiotics in this area.

文摘AIM: To investigate the effect of synbiotics, i.e. probiotics and prebiotics mixture, on the gut microbial ecology and digestive enzyme activities in rats. METHODS: Forty-eight SD rats weighing about 280 g were used in this study. Rats were divided into three groups according to the contents of probiotics and prebiotics mixture in the feed as control, low and high dose groups. The duration of the experiment was 8 wk. RESULTS: Compared with the control group, thefecal Lactobacillus and Bifidobacterium counts were significantly increased and the fecal Coliform organism counts were markedly reduced in the low and high dose groups. Concerning the digestive enzyme activity of jejunum, only lactase activity increased in low dose group. However, significant increase of lipase, lactase, sucrase, and isomaltase activities were observed in high dose group.CONCLUSION: Intake of low and high dosages of probiotics and prebiotics mixture significantly improved the ecosystem of the intestinal tract by increasing the probiotics population and digestive enzyme activities in rats.

文摘Background： Application the innovative method which is in ovo technology provides a means of modulating the immune system at early embryonic stages. The aim of study was to determine influence of the in ovo stimulation, on d12 of incubation, with synbiotics（synbiotic 1-L. salivarius IBB3154 ＋ Bi^2tos, Clasado Ltd. and the synbiotic 2-L. plantarum IBB3036 ＋ lupin RFOs） on the microstructure of duodenum, jejunum and ileum in the 1^（st） and 42^（nd）day of rearing.Results： On the 1^（st） day of chickens life, in the duodenum of both experimental groups（SYN1 and SYN2）, a significantly higher and wider intestinal vil i as wel as a significantly larger absorbent surface of these villi were found in comparison with the Control group（P ≤ 0.01）. On the 42^（nd）day of rearing the beneficial effect of synbiotic 1 was reflected by the numerical y higher vil i（no statistical differences） with a larger surface（P ≤ 0.01） in the duodenum in the SYN1 group compare to the Control group. In the jejunum on the 1^（st） day of life, in the SYN1 group, significantly higher vil i than in the Control group, with a simultaneous decrease in the depth of crypts（P ≤ 0.01）, and also the largest width of vil i and their absorbent area（P ≤ 0.01） in comparison to the other groups were found. On the 42^（nd）day of life, in the jejunum, an increase in the height of the vil i whilst reducing the crypt depth in the SYN2 group was found（P ≤ 0.01）. In turn, in the SYN1 group, there were significantly more neutral goblet cel s observed compared with the control group（P ≤ 0.05）. In the ileum of 1-day-old chickens, the widest vil i（P ≤ 0.05） and the deepest crypts（P ≤ 0.01） were found in the SYN2 group. In the same group, there was also the least amount of neutral goblet cel s in comparison to the other groups（P ≤ 0.05）.Conclusions： We observed that synbiotic 1 and 2 beneficial y affected the examined characteristics on the 1^（st） and 42^（nd） day of life. The obtained results al ow us to conclude that the use of synbiotics significantly affect gut structure which should contribute to improvement in nutrient absorption by the gut.

文摘The composition of gut microflora and its metabolic activity are closely correlated with the host immune system, and the changes in the biometric of the microbiome lead to inflammatory diseases like inflammatory bowel disease. The supplementation of probiotics and synbiotic could indeed manipulate the microflora, which can be an alternative therapy for ulcerative colitis, and Crohn's disease. Several in vitro, in vivo and clinical studies for the initiation and maintenance of remission in patients with inflammatory bowel disease have been completed.Those studies evaluated the efficacy of many probiotic formulations, especially about VSL#3.Even though the clinical studies proved that almost all the probiotic interventions are safe and bring improvement to patients, some studies are deficient in sample size, proper controls, and follow-ups. This paper summarizes the possible mechanism of inflammatory bowel disease development, probiotics, the clinical outcome of probiotic and synbiotic interventions for ulcerative colitis and Crohn's disease, as well as the adverse effect of probiotic treatments.
文摘The paper was to investigate the effects of synbiotics and antibiotics on nutrient digestibility and serum antioxidant function of weaned piglets. Totally 216 individuals of 35-day-old piglets were randomly divided into three groups, six replicates for each group, and each replicate contained 12 piglets. The first group was antibiotics group, 20 g,/t colistin sulfate （active ingredients） were added in the basal diet; the second group was synbiotics group, 250 g/t synbiotics （contai- ning xylooligesaccharides, oligochitasan, Bacillus subtilis and Clostridium butyricum） were added in the basal diet; the third group was combination group, 20 g/t colistin sulfate and 250 g/t synbiotics were added in the basal diet. The whole trial lasted 28 d. The results showed that there was no difference between synbiotics group and antibiotic group in growth performance, nutrients digestibility or antioxidant indicators （ P 〉 0.05 ）. Compared with the piglets in synbiotics group and an- tibiotic group, piglets in combination group had higher digestibility of dry matter and organic matter, and higher T-SOD activity in serum （ P 〈 0.05 ）. It is conclu- ded that synbiotics can replace antibiotics for piglets at 35 -63 days of age. Synbiotics and antibiotic had the synergistic effect on nutrient digestibility and antioxi- dant function of piglets.
文摘According to the increasing of human population in the world, it reached about seven billion people and it continuously increased. In this background, the food source in both animal and plant origin must be increased accordingly. For these we must use and add some feed additives such as antibiotic, probiotic, prebiotic, postbiotic and synbiotic for the animal feed to increase production (meat, egg, milk and fish) and improve health. In early cases, probiotic as mono or mixed beneficial live microorganism was used as feed additive that plays a significant role in several health conditions and performances. In another way, the scientists use some ingredients indigestible with carbohydrates origin, especially oligosaccharides as a source of energy for beneficial microorganisms in the body which were called prebiotic, and it is indigestible fermented food substrates that stimulate the growth, composition and activity of microorganisms in gastrointestinal and improve host. Most of the scientists urged to use all the above in such way that have more benefits in animal health and performance which were therefore called synbiotic, that was a combination between probiotic and prebiotic which beneficially had significant effects on the host by improving the survival and implantation of live microbial dietary supplements in the gastrointestinal tract, and thus improving animal health and performance. So, it was proposed that the synbiotic in this research increased beneficial microorganisms in the gastrointestinal tract and improved intestinal architect, and then promoted intestine environment. Consequently, it can improve blood indices, and especially decrease bad cholesterol (Low-density lipoprotein), decrease harmful microorganisms and toxins. However, it can also improve ingredient product, increase mineral absorption and nutrient. In conclusion, it can improve animal health and performance.

文摘Background: In order to discover new strategies to replace antibiotics in the post-antibiotic era in meat-type chicken production, two new synbiotics were tested:(Lactobacillus salivarius IBB3154 plus galactooligosaccharide(Syn1) and Lactobacillus plantarum IBB3036 plus raffinose family oligosaccharides(Syn2).Methods: The synbiotics were administered via syringe, using a special automatic system, into the egg air chamber of Cobb 500 broiler chicks on the 12 thday of egg incubation(2 mg of prebiotics + 105 cfu bacteria per egg).Hatched roosters(total 2,400) were reared on an experimental farm, kept in pens(75 animals per pen), with free access to feed and water. After 42 d animals were slaughtered. Blood serum, pancreas, duodenum and duodenum content were collected.Results: Syn2 increased trypsin activity by 2.5-fold in the pancreas and 1.5-fold in the duodenal content. In the duodenum content, Syn2 resulted in ca 30% elevation in lipase activity and 70% reduction in amylase activity.Syn1 and Syn2 strongly decreased expression of m RNA for GLP-1 and GIP in the duodenum and for GLP-1 receptors in the pancreas. Simultaneously, concentrations of the incretins significantly diminished in the blood serum(P < 0.05). The decreased expression of incretins coincides with changed activity of digestive enzymes in the pancreas and in the duodenal content. The results indicate that incretins are involved in the action of Syn1 and Syn2 or that they may even be their target. No changes were observed in key hormones regulating metabolism(insulin, glucagon, corticosterone, thyroid hormones, and leptin) or in metabolic indices(glucose,NEFA, triglycerides, cholesterol). Additionally, synbiotics did not cause significant changes in the activities of alanine and aspartate aminotransferases in broiler chickens. Simultaneously, the activity of alkaline phosphatase and gamma glutamyl transferase diminished after Syn2 and Syn1, respectively.Conclusion: The selected synbiotics may be used as in ovo additives for broiler chickens, and Syn2 seems to improve their potential digestive proteolytic and lipolytic ability. Our results suggest that synbiotics can be directly or indirectly involved in incretin secretion and reception.
文摘Objective: To evaluate whether addition of symbiotic to clindamycin could reduce Gardnerella vaginalis,Atopobium vaginae,and Megasphaera phylotypeⅠin pregnant women with bacterial vaginosis.Methods: This randomized controlled trial(RSUP Dr.Wahidin Sudirohusodo Makassar clinical trial registry UH17010021)included 61 samples.The intervention group was given clindamycin and synbiotic while the control group was given clindamycin and placebo(without synbiotic).Wilcoxon test and hypothesis test of two independent samples were used to compare the treatment efficacy.Results: This study showed a significant difference in Nugent score before and after treatment in each group.But there was no difference in Nugent score between the intervention group and the control group after treatment or in Nugent scores reduction in both groups.The most common type of bacteria found was Megasphaera phylotypeⅠ.There were no significant differences in the three types(Gardnerella vaginalis,Atopobium vaginae,and Megasphaera phylotypeⅠ)of bacteria after treatment between both groups.Additionally,there was no difference in therapeutic effect between the intervention group and the control group.Conclusions: Clindamycin along with synbiotics is no more effective for treated bacterial vaginosis than clindamycin without synbiotics.Megaesphaera is the most commonly found bacteria,which cannot be eradicated with clindamycin.

文摘Heat stress is one of the most challenging stressors for animal production due to high economic losses resulting from impaired animal’s productivity,health and welfare.Despite the fact that all farm animal species are susceptible to heat stress,birds and pigs are particularly sensitive to heat stress due to either lacking or non-functional sweat glands.Con-vincing evidence in the literature exists that gut dysbiosis,a term used to describe a perturbation of commensal gut microbiota,develops in broilers and pigs under heat stress.Owing to the protective role of commensal bacteria for the gut barrier,gut dysbiosis causes a disruption of the gut barrier leading to endotoxemia,which contributes to the typical characteristics of heat stressed broilers and growing and growing-finishing pigs,such as reduced feed intake,decreased growth and reduced lean carcass weight.A substantial number of studies have shown that feeding of probiotics,prebiotics and synbiotics is an efficacious strategy to protect broilers from heat stress-induced gut barrier disruption through altering the gut microbiota and promoting all decisive structural,biochemical,and immunologi-cal elements of the intestinal barrier.In most of the available studies in heat stressed broilers,the alterations of gut microbiota and improvements of gut barrier function induced by feeding of either probiotics,prebiotics or synbiot-ics were accompanied by an improved productivity,health and/or welfare when compared to non-supplemented broilers exposed to heat stress.These findings indicate that the restoration of gut homeostasis and function is a key target for dietary interventions aiming to provide at least partial protection of broilers from the detrimental impact of heat stress conditions.Despite the fact that the number of studies dealing with the same feeding strategy in heat stressed pigs is limited,the available few studies suggest that feeding of probiotics might also be a suitable approach to enhance productivity,health and welfare in pigs kept under heat stress conditions.
文摘Infection by Clostridium difficile, a complication of treatment with antibiotics, causes antibiotic- associated diarrhea (AAD) and can lead to colitis and pseudomembranous colitis. Incidence of C. difficile infection is increasing among the elderly undergoing antibiotics therapy confined to health care facilities, conditions that are expensive to treat, decrease the quality of life and are life threatening. Use of probiotics has been proposed as a method to decrease the incidence of AAD in health care facilities. To examine the efficacy of using probiotics, 120 nursing home residents undergoing antibiotic therapy were provided with a synbiotic tablet containing two probiotics, Saccharomyces boulardii and Bacillus coagulans, and a prebiotic, fructooligosaccharide. Residents were evaluated retrospectively for AAD and C. difficile infection. It was found that 95% of residents treated with antibiotics and taking the synbiotic tablet were free of AAD. More than 97% of the residents did not become infected with C. difficile. No adverse effects were reported. Minor side effects, gastrointestinal upset and nausea, were reported by less than 6% of the residents. The cause of the minor side effects was not known. Only 2.5% of the residents stopped taking the synbiotic tablet because of the gastrointestinal upset. These Results suggest that use of the synbiotic tablet prevents AAD and C. difficile infection in nursing home residents undergoing antibiotic therapy. It is concluded that this synbiotic tablet provides an easy to administer and safe approach to controlling AAD and C. difficile infection in residents in nursing homes.
文摘Nowadays consumers seek foods that not only provide basic nutrition but also contain compounds that contribute to health. Thus, different products have been designed to meet this demand, especially those with probiotic and prebiotic characteristics. This study aimed to evaluate different formulations of a soy-based synbiotic beverage. The composition and process conditions were defined using a Placket & Burman factorial design in which the independent variables were process temperature, concentrations of the soy hydrosoluble extract and fructooligosaccharides (FOS) and the initial concentration of the probiotics Bifidobaterium longum, Lactobacillus acidophilus, Lactobacillus paracasei subsp. Paracasei, Lactobacillus rhamnosus. Changes to the product by addition of sucrose, Streptococcus thermophilus and Lactobacillus delbrueckii subsp. Bulgaricus were also studied. Response parameters were: pH, cell concentration (plate counting), and quantification of fructooligosaccharides, acetic acid and lactic acid. The specific growth rate (μx) and change in cell count (Δx) were determined in each formulation. The soybean hydrosoluble extract was considered a good substrate for beverage production;FOS had a greater effect at lower concentrations. At the end of all fermentation tests the total probiotic count was greater than 7 log CFU/mL, meeting the legal requirements of a functional food. Lower temperatures were better for the growth of probiotics. The addition of sucrose resulted in a lower consumption of FOS by the fermenting microorganisms, while the presence of Streptococcus thermophilus and Lactobacillus delbrueckii subsp. bulgaricus represented little change concerning the evaluated characteristics. Therefore, according to the results of this study, the production of a soy-based symbiotic fermented beverage can be performed using soybean hydrosoluble extract at 10% (w/v), fructooligosaccharides at about 3% (w/v), sucrose at 12% (w/v), and the process temperature should be maintained at 35℃. Initial probiotic concentrations need not exceed 5 × 106 CFU/ml.
文摘<strong>Introduction:</strong> COVID-19 pandemic caused by the novel coronavirus SARS-CoV-2 increasingly involves people worldwide. Probiotics can improve immune system functions via different mechanisms. We proposed that Synbiotic Lactocare<span style="white-space:nowrap;"><sup><span style="white-space:nowrap;"><span style="white-space:nowrap;">?</span></span></sup></span> may also reduce SARS-Cov2 infection in high-risk medical staff working in COVID-19 hospital wards. <strong>Method:</strong> In a randomized, controlled trial, 60 hospital staff without any history of clinical or laboratory evidence of SARS-Cov2 infection were received either once-daily oral synbiotic capsule (Lactocare<span style="font-size:10px;"><sup><span style="white-space:nowrap;"><span style="white-space:nowrap;">?</span></span></sup></span>) that contains 1 billion CFU/Cap of L. (Lactobacillus) casei, <em>L. rhamnosus</em>, <em>Streptococcus thermophilus</em>, <em>Bifidobacterium breve</em>, <em>L. acidophilus</em>, <em>Bifidobacterium infantis</em>, <em>L. bulgaricus</em>, and Fructooligosacharide (Zist Takhmir, Tehran, Iran) or placebo with the same appearance for 30 days. They were followed for two months. <strong>Result:</strong> During the two-month period of this study, SARS-COV-2 RT-PCR test results were positive in three participants (9.67%) in placebo group compared to zero positive tests in synbiotic group. The differences were not statistically significant (p = 0.238). During the study, two persons (7 %) of placebo group had respiratory complaints such as cough, rhinorrhea and/or dyspnea, compared with one in synbiotic group (p = 0.492). <strong>Conclusion:</strong> This study showed that overall frequency of SARS-COV2 infection in participants receiving synbiotic and those receiving placebo did not differ significantly. However, 3 hospital staff in placebo group compared to no one in synbiotic group had SARS-COV2 infection. Further studies with greater power and alternative probiotic strains and mixture are warranted to determine whether Synbiotic can prevent COVID-19 in at-risk hospital staff.
