Serotypes and virulence profiles of non-O157 Shiga toxin-producing Escherichia coli isolates from bovine farms.
Non-O157 Shiga toxin-producing Escherichia coli (STEC) strains are clinically significant food-borne pathogens. However, there is a dearth of information on serotype prevalence and virulence gene distribution, data essential for the development of public health protection monitoring and control activities for the meat and dairy industries. Thus, the objective of this study was to examine the pr...
متن کاملSerotypes, virulence genes, and PFGE patterns of enteropathogenic Escherichia coli isolated from Cuban pigs with diarrhea.
Thirty-six enteropathogenic Escherichia coli strains isolated from Cuban pigs with diarrhea were serotyped and screened by PCR for the presence of virulence genes. The 36 isolates belonged to 11 O serogroups and 14 O:H serotypes, with 53% of the isolates belonging to only two serotypes: O141:H- (13 isolates) and O157:H19 (6 isolates). Genes coding for STb, STa, VT2e, and LT toxins were identifi...
متن کاملCharacterization of monkey enteropathogenic Escherichia coli (EPEC) and human typical and atypical EPEC serotype isolates from neotropical nonhuman primates.
Enteropathogenic Escherichia coli (EPEC) has been associated with infantile diarrhea and mortality in humans in developing countries. While diarrhea is also a major problem among primates kept in captivity, the role of E. coli is unclear. This study was designed to characterize diarrheagenic E. coli recovered from the feces of 56 New World nonhuman primates, primarily marmosets (Callithrix spp....
متن کاملSerotypes, virulence profiles and stx subtypes of Shigatoxigenic Escherichia coli isolated from chicken derived products.
Shigatoxigenic Escherichia coli (STEC) is a foodborne pathogen that causes hemolytic uremic syndrome (HUS) and the consumption of chicken products has been related to some HUS cases. We performed a non-selective isolation and characterization of STEC strains from retail chicken products. STEC isolates were characterized according to the presence of stx1, stx2, eae, saa and ehxA; stx subtypes an...
متن کاملserotypes of enteropathogenic escherichia coli isolated from children under 5 years of age
background: the purpose of this study was to find out the frequency of different serotypes of enteropathogenic escherichia coli (epec) among healthy/diarrheal cases. methods: a total of 191 strains, 111 from diarrheal and 80 from asymptomatic persons were examined. determination of the epec serogroups was performed by agglutination tests using polyvalent and monovalent o antiserum. pcr-rflp a...
