RESERVOIR OF ANTIMICROBIAL RESISTANT SALMONELLAE AMONG POULTRY IN OGUN STATE, NIGERIA

Abstract

A survey was carried out to determine the reservoir of antimicrobial resistant Salmonellae among poultry in a local government in Ogun State, Nigeria. Isolation and identification of Salmonellae strains mainly from faecal samples of non-clinical birds and blood samples from few clinical cases were carried out. The resistance profile of the Salmonellae isolates was determined by disc-diffusion method. The results indicated relative large number of resistant Salmonellae  from birds. Young birds, duck, exotic hens and intensively reared birds are useful characteristics for identifying birds likely to carry resistant Salmonella. Resistance to ampicilin, cephalexin and cefuroxine are highest among the tested drugs. In all, 22 resistant phenotypes were identified. Thirty-two out of 38 isolates were multi-resistant.
