Ninety-five Escherichia coli isolates from bovine mastitis, 47 isolates from milking machine filters, 36 enterotoxigenic (ETEC) and 43 verocytotoxigenic (VTEC) isolates from cows were examined for the ability to resist the bactericidal effects of 90% gnotobiotic calf serum. There was no significant difference in the percentage of isolates in each group which demonstrated resistance. Two potential virulence traits, the traT gene and the K1 capsular antigen, previously shown to be related to… CONTINUE READING
