diarrheal diseases can be caused by viral, bacterial and parasitic infections. this paper provides a preliminary image of diarrhea with regards to etiology and epidemiologic factors in tunisian children less than five years of age.overall, 124 diarrhoeal stools were collected from patients suffering from acute diarrhea and 54 stool samples from healthy children. all stools were examined for the...
background and objectives: loop-mediated isothermal amplification is a novel nucleic acid amplification assay providing as a simple diagnostic tool for rapid identification of microbial diseases in developing countries. in this study, a lamp assay was established for yersinia enterocolitica , a leading cause of acute enterocolitis in young children. materials and methods: lamp assay was establi...
Since the turn of the century, Escherichia coli has been implicated in the etiology of weanling diarrhea (colibacillosis). However, rotavirus--a virus that destroys enterocytes--has been shown recently to be causally associated with weanling diarrhea of pigs. The role of both rotavirus and hemolytic enteropathogenic E. coli in weanling diarrhea was assessed in this study. Pigs from a closed her...
Escherichia coli (E. coli) is a normal inhabitant of the gastrointestinal tract of vertebrates, including humans. Phylogenetic analysis has shown that E. coli is composed of four main phylogenetic groups (A, B1, B2 and D). Group A and B1 are generally associated with commensals, whereas group B2 is associated with extra-intestinal pathotypes. Most enteropathogenic isolates, however, are assigne...
A total of 220 enteroadherent Escherichia coli were identified from 729 Egyptian children with diarrhea using the HEp-2 adherence assay. Enteropathogenic E.coli (EPEC = 38) was common among children <6 months old and provoked vomiting, while diffuse-adhering E.coli (DAEC = 109) induced diarrheal episodes of short duration, and enteroaggregative E.coli (EAEC = 73) induced mild non-persistent dia...
Enteropathogenic Escherichia coli (EPEC) induces formation of actin pedestals in infected host cells. Agents that inhibit the activity of Rho, Rac, and Cdc42, including Clostridium difficile toxin B (ToxB), compactin, and dominant negative Rho, Rac, and Cdc42, did not inhibit formation of actin pedestals. In contrast, treatment of HeLa cells with ToxB inhibited EPEC invasion. Thus, Rho, Rac, an...
