Prevalence of CS31A and F165 surface antigens in Escherichia coli isolates from animals in France, Canada and India.
Bovine and porcine enterotoxigenic and non-enterotoxigenic Escherichia coli isolates from France, Canada, and India were characterized with respect to serogroup and production of fimbrial antigens CS31A and F165. Of 231 bovine isolates from the 3 countries, 20.5% produced CS31A alone, 17.7% produced F165 alone, and 17.3% produced both CS31A and F165. On the other hand, of 84 porcine isolates from Canada, 1.2% produced CS31A alone, 14.3% produced F165 alone, and no isolate produced both CS31A and F165. CS31A was found together with F5 (K99) in 7 of 16 bovine enterotoxigenic E. coli isolates of serogroups 08, 09, 020, and 023, but was not found in any of 20 F4 (K88)- or 5 F6 (987P)-positive porcine enterotoxigenic E. coli isolates. F165 was not found in enterotoxigenic E. coli. Among non-enterotoxigenic isolates, CS31A and F165 were mainly associated with serogroups 08, 09, 011, 015, 017, 023, 025, 078, 0101, 0115, 0117, 0141, and 0153.
