Origin of contamination and genetic diversity of Escherichia coli in beef cattle

Article Abstract:

Research has been conducted on Escherichia coli populations in beef cattle. The authors have investigated beef contamination origin and genetic diversity of these populations via the use of random application of polymorphic DNA and PCR-restriction fragment length polymorphism analysis of fliC gene, and they report good agreement between the results obtained by these techniques.

Prevalence and characteristics of eae-positive Escherichia coli from healthy cattle in Japan

Article Abstract:

Research has been conducted on eae-positive Escherichia coli. The authors have investigated the prevalence of eae-positive E. coli in cattle feces, and have genetically characterized the discovered intimin types and the virulence genes from the isolated strains.

Concentration and prevalence of Escherichia coli O157 in cattle feces at slaughter

Article Abstract:

Research has been conducted on Escherichia coli O157 prevalence in cattle feces at slaughter time. Results demonstrate that the presence of high-shedding animals at the abattoir increases the risk of meat contamination during cattle slaughtering.
