Prevalence of Escherichia coli O157:H7 in gallbladders of beef cattle
Article Abstract:
Gallbladders and rectal contents from cattle (n=933) at slaughter were collected to determine whether the gallbladder harbors Escherichia coli 0157:H7. The gallbladder was not found to be a common site of colonization for Escherichia coli 0157:H7 in beef cattle so it could not serve as a source for fecal shedding or contamination of meat at slaughter.

Comparison of rectoanal mucosal swab cultures and fecal cultures for determining prevalence of Escherichia coli O157:H7 in feedlot cattle
Article Abstract:
The fecal samples were compared with the samples collected with rectoanal mucosa swabs (RAMS) to determine the prevalence of Escherichia coli O157 in feedlot cattle. Escherichia coli O157 was detected in 9.5% of samples collected with the RAMS and 4.7% of samples tested by fecal culture.
