Metapopulation dynamics of Escherichia coli O157 in cattle: an exploratory model.
Livestock movement is thought to be a risk factor for the transmission of infectious diseases of farm animals. Simple mathematical models were constructed for the transmission of Escherichia coli serogroup O157 between Scottish cattle farms, and the models were used in a preliminary exploration of factors contributing to the levels of infection reported in the field. The results suggest that ca...
متن کاملPCR detection of Escherichia coli O157:H7 directed from slaughtered cattle in Shiraz, Iran
Escheric hia coli O157:H7 lives in the intestines of healthy cattle, and can contaminate meat during slaughtering pr actices . Detection of the low infectious dosage of bacterium requires a sensitive method. We developed polymerase chain reaction (PCR) assays to detect the gene Stx2 irrespective of the bacterial serotype. In this study, the detection limit of the PCR protocol in detecting Stx...
متن کاملRectal carriage of enterohemorrhagic Escherichia coli O157 in slaughtered cattle.
Escherichia coli O157:H7 is an important cause of diarrhea, hemorrhagic colitis, and potentially fatal human illness. Cattle are considered a primary reservoir of infection, and recent experimental evidence has indicated that the terminal rectum is the principal site of bacterial carriage. To test this finding in naturally colonized animals, intact rectum samples from 267 cattle in 24 separate ...
متن کاملEscherichia coli O157:H7 in environments of culture-positive cattle.
Outbreaks of Escherichia coli O157:H7 disease associated with animal exhibits have been reported with increasing frequency. Transmission can occur through contact with contaminated haircoats, bedding, farm structures, or water. We investigated the distribution and survival of E. coli O157:H7 in the immediate environments of individually housed, experimentally inoculated cattle by systematically...
متن کاملPreharvest control of Escherichia coli O157 in cattle.
Bovine manure is an important source of Escherichia coli O157 contamination of the environment and foods; therefore, effective interventions targeted at reducing the prevalence and magnitude of fecal E. coli O157 excretion by live cattle (preharvest) are desirable. Preharvest intervention methods can be grouped into 3 categories: 1) exposure reduction strategies, 2) exclusion strategies, and 3)...
