Occurrence of virulence genes associated with Diarrheagenic pathotypes in Escherichia coli isolates from surface water.
Escherichia coli isolates (n = 300) collected from six sites in subtropical Brisbane, Australia, prior to and after storm events were tested for the presence of 11 virulence genes (VGs) specific to diarrheagenic pathotypes. The presence of eaeA, stx(1), stx(2), and ehxA genes specific for the enterohemorrhagic E. coli (EHEC) pathotype was detected in 56%, 6%, 10%, and 13% of isolates, respectiv...
متن کاملDiarrheagenic Escherichia coli pathotypes frequency in Khuzestan province of Iran
BACKGROUND AND OBJECTIVES Diarrheagenic Escherichia coli (DEC) is an emerging agent among pathogens that causes diarrhea. Studies showed that diarrheagenic E. coli such as enterohaemorrhagic E. coli (EHEC), enteroaggregative E. coli (EAEC), enteropathogenic E. coli (EPEC), enteroinvasive E. coli (EIEC), enterotoxigenic E. coli (ETEC), diffusely adhering E. coli (DAEC) and shiga toxin producing ...
متن کاملEscherichia coli pathotypes occupy distinct niches in the mouse intestine.
Since the first step of the infection process is colonization of the host, it is important to understand how Escherichia coli pathogens successfully colonize the intestine. We previously showed that enterohemorrhagic O157:H7 strain E. coli EDL933 colonizes a niche in the streptomycin-treated mouse intestine that is distinct from that of human commensal strains, which explains how E. coli EDL933...
متن کاملMolecular characterization of uropathogenic and diarrheagenic Escherichia coli pathotypes.
In this study diarrheagenic and uropathogenic Escherichia coli (UPEC) strains were comparatively characterized according to serotype, hemolytic activity, protein polymorphism among housekeeping enzymes, phylogenetic group and urovirulence genes. Intra-serogroup/serotype variations were observed. Hemolytic activity was detected in 100%, 93%, 67% and 39% of UPEC, EAEC, EPEC and ETEC strains, resp...
متن کاملOccurrence and Antibiotic Resistance of Escherichia coli in Street-Vended Kebab in Dramaga, Bogor, Indonesia
Background: Kebab is one of the popular ready-to-eat foods in Indonesia and sold as a street food. The purpose of this study was to determine occurrence and antibiotic resistance of Escherichia coli in street-vended kebab in Dramaga, Bogor, Indonesia. Methods: Totally, 43 samples of kebab meat were collected from street food kebab vendors. Examinations on Total Plate Count (TPC), and total E. ...
