An epidemiological study ofPseudomonas aeruginosain cattle and other animals by pyocine typing

Abstract

SUMMARYThe high incidence (80·1%) ofPseudomonas aeruginosapyocine type 1 in bovine mastitis in Israel suggested some degree of selectivity under local conditions. Contrary to other reports, cattle and calves showed a high rate of faecal carriage of this organism. The water supply on farms was often contaminated. The presence of certain pyocine types in the udder, gut or water occasionally led to their transmission from one reservoir to another; however, many types did not seem to spread.P. aeruginosawas found in association with infections in various animals and was present in many locations such as a mouse breeding house and a chick hatchery.
