Enterohemorrhagic Escherichia coli (EHEC) is a significant zoonotic pathogen causing severe disease associated with watery and bloody diarrhea, hemorrhagic colitis, and the hemolytic-uremic syndrome (HUS) in humans. Infections are frequently associated with contact with EHEC-contaminated ruminant feces. Both natural and experimental infection of cattle induces serum antibodies against the LEE-e...

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 ...

A retrospective epidemiological case-control study was performed in Karachi, Pakistan, from January to April 2013. The owners of 217 dairy cattle and buffalo farms from six different locations in Karachi were interviewed. The aim of the study was to identify risk factors associated with the presence of haemorrhagic septicaemia (HS). Farms with a history of at least one instance of sudden death ...

Escherichia coli O157:H7 is found in cattle farms and can live in the intestine of healthy cattle. Mostcases of human illnesses including nonbloody diarrhea, hemorrhagic colitis and hemolytic uremic syndromecan be traced, either directly or indirectly, to cattle. One strategy for reducing the risk of EnterohemorrhagicEscherichia coli (EHEC) infections in human is to reduce the prevalence of inf...

This study was an attempt to devise productive orientations of cattle herds in eastern high plains of Algeria. In this regard, 165 farms randomly identified were investigated. The selection of breeders was based to existence of cattle on the farm, and the farmer proposed to investigation must have at least two cows. The approach taken was to identify all systems adopted by farmers in a region t...

OBJECTIVE To describe the frequency and distribution of Escherichia coli O157:H7 in the feces and environment of cow-calf herds housed on pasture. SAMPLE POPULATION Fecal and water samples for 10 cow-calf farms in Kansas. PROCEDURE Fecal and water samples were obtained monthly throughout a 1-year period (3,152 fecal samples from 2,058 cattle; 199 water samples). Escherichia coli O157:H7 in ...

BACKGROUND The aim of this study was to estimate the seroprevalence of Coxiella burnetii in dairy goat farms in the Netherlands and to identify risk factors for farm and goat seropositivity before mandatory vaccination started. We approached 334 eligible farms with more than 100 goats for serum sampling and a farm questionnaire. Per farm, median 21 goats were sampled. A farm was considered posi...

A study was conducted on 440 dairy cattle in six organized dairy farms in the state of Himachal Pradesh, India using tuberculin skin testing (TST) to determine the prevalence of bovine tuberculosis. An overall animal prevalence of 14.31% (63 of 440 animals) and a farm prevalence of 16.67% (1 of 6 farms) were recorded in 6 dairy farms by the TST. Of the six dairy farms studied, one of the farms ...

Although Salmonella spp., Escherichia coli O157, Listeria monocytogenes, Enterococcus faecalis and Clostridium spp. present a significant food safety and/or spoilage issue for the beef sector, there are limited data on their prevalence in Irish cattle. The objectives of this preliminary study were to investigate distribution (percentage farms positive) E. L. overall (%) these bacteria cattle sm...
