Twenty-two enterotoxigenic Escherichia coli (ETEC) O8:KX105 strains isolated from 1- to 7-week-old diarrheic piglets were examined for virulence properties. Thirteen strains caused acute watery diarrhea in orally infected, colostrum-deprived newborn piglets, whereas the remaining nine did not. The enteropathogenic strains colonized the small intestine, albeit with lower intensity than classical...

Enteropathogenic Escherichia coli infection of intestinal epithelial cells leads to localized depletion of the microtubule cytoskeleton, an effect that is dependent on delivery of type III translocated effector proteins EspG and Orf3 (designated EspG2) to the site of depletion. Microtubule depletion involved disruption rather than displacement of microtubules.

A successful infection of the human intestine by enteropathogenic bacteria depends on the ability of bacteria to attach and colonize the intestinal epithelium and, in some cases, to invade the host cell, survive intracellularly and disseminate from cell to cell. To accomplish these processes bacteria have evolved an arsenal of molecules that are mostly secreted by dedicated type III secretion s...

BACKGROUND Diarrhoea is a serious threat all over the world with great economic implications especially evident in the developing world. This study was aimed at determining in vitro efficacy of Zinc (Zn) against common enteric bacterial pathogens. METHOD A total of 100 bacterial enteric pathogens: Salmonellae (n = 16), enteropathogenic Escherichia coli (EPEC) (n = 26). Shigellae (n = 28) and ...

The etiological roles of diarrheagenic Escherichia coli (DEC), including enteroaggregative E. coli (EAggEC), diffusely adherent E. coli (DAEC) and EAST1EC--a strain of E. coli that possesses no diarrheagenic characteristics other than the EAggEC heat-stable toxin 1 (EAST1) gene--remain controversial. To clarify the prevalence of DEC among healthy individuals in Osaka City, Japan, and to compare...

background and objectives: pathogenic strains of escherichia coli are a common cause of acute infectious diarrhea. the aim of this study was to investigate the frequency, virulence markers and antibiotic resistance patterns of diarrheagenic e. coli (dec) isolated from adolescents and adults in hamadan, west of iran. materials and methods: a total of 187 stool samples were collected from adults ...
