Preputial fluid samples were collected from 90 bulls in two Ontario artificial insemination units using a penial glove swab technique previously developed by one of us for use in donor bulls. No Campylobacter fetus organisms were identified from the prepuce or from samples of semen collected at the same time from these bulls. The distal genitalia of 200 bulls were collected at a slaughter house. One isolation of a Campylobacter fetus subspecies venerealis was obtained on a culture from the fornix area of the prepuce of one of these bulls.
