serotypes 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...
متن کاملA STUDY OF SALMONELLA, SHIGELLA AND ENTEROPATHOGENIC ESCHERICHIA COLI SEROTYPES IN ACUTE GASTROENTERITIS CHILDREN UNDER THE AGE OF FIVE
In this study, it has been our purpose to isolate and serotype enteropathogenic E. coli, salmonella and shigella and determine their resistance to antibiotics. 502 swab specimens were collected during mid-July to midNovember. 1986. from two children's hospitals in Tenran. From 502 cultured specimens. 108 specimens were positive for salmonella. shigella and enteropathogenic E. coli. corresp...
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 کاملoccurrence of shv, tem and ctx-m β-lactamase genes among enteropathogenic escherichia coli strains isolated from children with diarrhea
conclusions our study emphasized the increasing role of esbl genes, especially blactx-m15 in epec isolates. results of 42 epec, eight isolates carried the blactx-m1. none of the isolates carried blactx-m2 and blactx-m9. the blactx-m15 variant was identified in all of blactx-m1-positive isolates. furthermore, blashv and blatem genes were detected in 40.5% (n = 17) and 19% (n = 8) of all epec iso...
متن کاملMolecular characterization of enterotoxigenic Escherichia coli isolated from neonatal calves diarrhea
Enterotoxigenic Escherichia coli (ETEC) produces different virulence factors allowing the bacterium to colonize and develop watery diarrhea. Proteomics studies have also introduced new protein belonging to the secretion pathways, antigen 43 (Ag43), which plays important role in E. coli pathogenesis. The objective of this study was to investigate O-types and virulence factors o...
