the role of enterotoxigenic e.coli as a causative agent in diarrheal disease was studied among 100 cases of infant and children 0-2 years of age. routine bacteriological methods were used for identification enteropathogenic e.coli, salmonella, shigella and vibrio cholera. the ability of e.coli strains to produce toxin was assayed in animal models (rebbit-ileal loop and suckling mice) and in tis...

background and objectives: diarrhea is one of the most prevalent diseases in the world, specially in developing countries. one of the most important causative agents of bacterial diarrhea is diarrheagenic escherichia coli (dec) which causes gastroenteritis and this group involving enterotoxigenic e. coli (etec), enteropathogenic e. coli (epec), enteroaggregative e. coli (eaec), enterohemoragic ...

background: probiotic therapies with different strains demonstrated some beneficial effects, although some studies did not show any significant effects. this study assessed systematically the current knowledge on the effect of probiotic bacteria on duration of in acute rotavirus diarrhea in children compared with control. methods: the pubmed, cochrane controlled trial register (cctr) and ovid (...

conclusions based on the low level of knowledge and practice among the study population, the usual practice of focusing on a target group would be necessary. our findings indicated a serious lack of competence in dealing with this problem. results the findings indicated that knowledge of the majority of mothers (64.3%) regarding diarrhea and diet was moderate and only 3.7% had good knowledge. t...

The correlation between maternal serum antibodies in beef calves at 2 days old and protection against diarrhea induced by natural bovine rotavirus (BRV) infection was examined. Virus neutralizing (VN) antibody titers against BRV in sera from calves that developed diarrhea by BRV infection within 14 days of age (BRV-diarrheal calves) were significantly lower than those from calves that had no di...

BACKGROUND Recent studies indicate that ambient temperature could be a risk factor for infectious diarrhea, but evidence for such a relation is limited in China. METHODS We investigated the short-term association between daily temperature and physician-diagnosed infectious diarrhea during 2008-2010 in Shanghai, China. We adopted a time-series approach to analyze the data and a quasi-Poisson r...
