Comparison of shiga-toxigenic Escherichia coli prevalences among dairy, feedlot, and cow-calf herds in Washington State.

چکیده
Shiga-toxigenic Escherichia coli (STEC) strains were isolated from 7.4% of 1,440 fecal and farm environmental samples. Shiga toxin gene and STEC prevalences were significantly associated with animal production type and season. A range of serogroups were identified. Nine percent of isolates possessed all three principal virulence markers: stx(2), eae, and ehx.

Horizontal transmission of Shiga toxin-producing Escherichia coli within groups of dairy calves.
To examine the dissemination of Shiga-toxigenic Escherichia coli (STEC) within cattle groups, dairy calves on two farms utilizing different calf-rearing practices were exposed to a traceable STEC strain. Test strain dissemination differed significantly between farms, with a higher prevalence being associated with group penning. Pen floors and calf hides may be the main environmental mechanisms ...

In this study 130 bulk tank milk samples which were delivered to the Pegah Pasturisation Factory inMashhad were collected randomly during the summer months. Samples were firstly enriched in modifiedtrypticase soy broth containing novobiocin, followed by plating onto sorbitol MacConkey agar supplementedwith cefixime and potassium tellurite for isolation of Escherichia coli O157:H7. Consequently ...

Shiga toxin-producing Escherichia coli (STEC) are food-borne pathogens primarily associated with the consumption of contaminated ground beef and are an important food safety concern worldwide. STEC has been found to produce a family of related cytotoxins known as Shiga toxins (Stxs). Shiga toxins have been classified into two major classes, Stx1 and Stx2. A single strains of STEC can produce St...
متن کاملCost-effectiveness of farm interventions for reducing the prevalence of VTEC O157 on UK dairy farms.
A randomized control trial on verocytotoxigenic Escherichia coli (VTEC)-infected farms found evidence that: (1) keeping animals in the same group; (2) maintaining dry bedding; (3) preventing direct contact with neighbouring cattle; and (4) maintaining a closed herd, were associated with a reduced risk of infection in youngstock aged 3–18 months. This study evaluated these interventions using a ...
