Surface properties of the Vero cytotoxin-producing Escherichia coli O157:H7.
Strains of Escherichia coli serotype O157:H7 are Vero cytotoxin-producing enteric pathogens which have been associated with sporadic cases and outbreaks of hemorrhagic colitis and with the hemolytic uremic syndrome in humans. In addition to toxin production, adherence of many pathogenic bacteria to intestinal mucosal surfaces is a critical primary step in the pathogenesis of diarrheal diseases....
متن کاملThe surveillance of vero cytotoxin-producing Escherichia coli O157 in Wales, 1990 to 1998.
Population-based surveillance for Vero cytotoxin-producing Escherichia coli (VTEC) O157 has been carried out in Wales since 1990. The annual incidence has remained stable during the 9-year period (mean: 1.6 cases per 100,000 population); the rate is highest in children younger than 5 years of age. Blood in the stool is reported in fewer than half the cases, indicating the importance of screenin...
متن کاملVero Cytotoxin–Producing Escherichia coli O157 Gastroenteritis in Farm Visitors, North Wales
An outbreak of Vero cytotoxin-producing Escherichia coli O157 (VTEC O157) gastroenteritis in visitors to an open farm in North Wales resulted in 17 primary and 7 secondary cases of illness. E. coli O157 Vero cytotoxin type 2, phage type 2 was isolated from 23 human cases and environmental animal fecal samples. A case-control study of 16 primary case-patients and 36 controls (all children) showe...
متن کاملComparison of Vero-cytotoxin-encoding phages from Escherichia coli of human and bovine origin.
Phages encoding production of Vero cytotoxins VT1 or VT2 were isolated from strains of Escherichia coli of human and bovine origin. Two human strains of serotype O157: H7 produced both VT1 and VT2 and each carried two separate phages encoding either VT1 or VT2. The phages were morphologically similar to each other and to a VT2 phage previously isolated from a strain of serotype O157: H-; all ha...
متن کاملMolecular Characterization of Enterohemorrhagic Escherichia coli Isolates from Cattle
A total of 21 (4.3%) enterohemorrhagic E. coli strains were isolated by biochemical tests and identification of the eae(+)stx1(+)stx2(+) genotype from 490 stool samples obtained from calves with diarrhea during 1-year period from a major farm in Tehran, Iran. All of the strains showed resistance to ampicillin, ciprofloxacin, trimethoprim, streptomycin, chloramphenicol and tetracycline, while 19...
