Prevalence of Escherichia coli O157 isolated from marketed raw cow milk in Kwara State, Nigeria

open access: yesScientific African, 2023
Escherichia coli (E. coli) is a common cause of poor milk microbial quality, often resulting from unhygienic milk handling. Here, a cross-sectional study was performed to determine the prevalence and antibiotic susceptibility profile of E.

The long polar fimbriae (lpf) operon and its flanking regions in bovine Escherichia coli O157:H43 and STEC O136:H12 strains [PDF]

open access: yes, 2013
Long polar fimbriae (Lpf) are intestinal adhesins and important virulence factors of pathogenic Escherichia coli strains. We cloned and sequenced the lpf2-1 operon (lpf2ABCD) and its flanking regions of an intimin- and Shiga toxin-negative E.

Rectoanal junction colonization of feedlot cattle by Escherichia coli O157:H7 and its association with supershedders and excretion dynamics [PDF]

open access: yes, 2006
Feedlot cattle were observed for fecal excretion of and rectoanal junction (RAJ) colonization with Escherichia coli O157:H7 to identify potential "supershedders." RAJ colonization and fecal excretion prevalences were correlated, and E.

Cattle intestinal microbiota shifts following Escherichia coli O157:H7 vaccination and colonization

open access: yesPLoS ONE, 2019
Vaccination-induced Escherichia coli O157:H7-specific immune responses have been shown to reduce E. coli O157:H7 shedding in cattle. Although E. coli O157:H7 colonization is correlated with perturbations in intestinal microbial diversity, it is not yet ...

Occurrence, virulence genes, and antimicrobial profiles of Escherichia coli O157 isolated from ruminants slaughtered in Al Ain, United Arab Emirates

open access: yesBMC Microbiology, 2020
Background Shiga toxin-producing Escherichia coli (STEC) is a major source of food-borne illness around the world. E. coli O157 has been widely reported as the most common STEC serogroup and has emerged as an important enteric pathogen.

Comparative genomic analysis of a multiple antimicrobial resistant enterotoxigenic E. coli O157 lineage from Australian pigs [PDF]

open access: yes, 2015
© 2015 Wyrsch et al. Background: Enterotoxigenic Escherichia coli (ETEC) are a major economic threat to pig production globally, with serogroups O8, O9, O45, O101, O138, O139, O141, O149 and O157 implicated as the leading diarrhoeal pathogens affecting ...

Comparative Pathogenicity of Wildlife and Bovine Escherichia coli O157:H7 Strains in Experimentally Inoculated Neonatal Jersey Calves

open access: yesVeterinary Sciences, 2018
Shiga toxin-producing Escherichia coli, like E. coli O157:H7, are important human and animal pathogens. Naturally-acquired E. coli O157:H7 infections occur in numerous species but, particularly, cattle have been identified as a significant reservoir for ...

InstantLabs®E. coli O157 Food Safety Kit

open access: yesJournal of AOAC INTERNATIONAL, 2015
Abstract The InstantLabs®E. coli O157 Food Safety Kit was validated against the International Organization for Standardizationreference method 16654 for the detection of Escherichia coli O157. The matrixes, raw ground beef, raw beef trim, Romaine lettuce, pasteurized apple juice, and raw ground chicken, were inoculated with appropriate ...
