Abstract
Three different methods of collecting preputial material for bacteriological examination were compared using 3 bulls infected with Campylobacter fetus subsp. fetus. The first method utilised a specially designed instrument to scrape the preputial and penile mucosa, int he second method plastic pipettes were used to aspirate material and the third method involved washing the preputial cavity with sterile peptone water. Bacteriological examination of the samples showed conclusively that scraping was the method of choice because more C. fetus positive samples were identified and there was less interference from contaminating organisms.
