distribution of enterotoxigenic escherichia coli among e. coli isolates from diarrheal samples referred to educational hospitals in tehran-iran
background: introduction: enterotoxigenic escherichia coli (etec) is the most important bacterial cause of watery travelers' diarrhea in developing countries. watery diarrhea is can cause serious life-threatening dehydration. etec was caused diarrhea by the secretion of two heat-labile enterotoxins (lts) and the heat-stable enterotoxins (sts) which increase intestinal secretion. routine labo...
متن کاملEscherichia Coli in Diarrheal Disease
Transmission is by the fecal-oral route. Pili (fimbriae) allow the bacteria to colonize the ileal mucosa. Cytotonic enterotoxins (encoded on plasmid or bacteriophage DNA) induce watery diarrhea. Plasmid-encoded invasion factors permit invasion of the mucosa, and plasmidor bacteriophage-encoded cytotoxic enterotoxins induce tissue damage; the presence of either of these factors induces a host in...
متن کاملThe impact of infant feeding patterns on infection and diarrheal disease due to enterotoxigenic Escherichia coli.
OBJECTIVE Determine the impact of dietary risk factors on patterns of infection by heat labile toxin-producing Escherichia coli (LT-ETEC). MATERIALS AND METHODS Ninety-eight infants were followed from birth for one year in Guadalajara, Mexico, beginning in august of 1986. Stool and breast milk samples were collected weekly from infants and their mothers, respectively. Mothers were also interv...
متن کاملPhylogenetic background of enterotoxigenic and enteroinvasive Escherichia coli from patients with diarrhea in Sirjan, Iran
BACKGROUND AND OBJECTIVES Diarrheagenic Escherichia coli (DEC) strains are a major cause of intestinal syndromes in the developing countries. The aim of this study was to determine the prevalence of enterotoxigenic E. coli (ETEC) and enteroinvasive E. coli (EIEC) in relation to phylogenetic background from patients with diarrhea. MATERIALS AND METHODS A total of 110 E. coli isolates were obta...
متن کاملMolecular Differentiation of Shigella Spp. from Enteroinvasive E. Coli
A real-time polymerase chain reaction (PCR) assay, amplifying the genes encoding lactose permease (lacY) and invasion plasmid antigen H (ipaH), was run on 121 isolates phenotypically classified as Shigella spp., enteroinvasive Escherichia coli (EIEC), or EIEC O nontypable (ONT). The results were compared with data from a generic E. coli multiple-locus variable-number of tandem repeat analysis (...
