Seven commonly used disinfectants abbreviated as A, B, C, D, E, F and G (A is, Glutaraldehyde and Coco – benzyl dimethyl ammonium chloride; B is, Didecyldimethyl ammonium bromide 50% w\\v; C is, Sodium hypochlorite; D is, pine disinfectant and antiseptic; E is, chloroxylenol; F is, phenol and that for disinfectant G is, cresol and soap solution) were evaluated for their effectiveness in disinfecting coops and premises of indigenous chickens and ducks. Bacterial isolates from 14 samples (each sample comprising of a pharyngeal and a cloacal swab from one bird pooled together) from village chickens and ducks were used in this study. The isolates were taken to represent microorganisms in the birds\' environment. Results showed that effectiveness amongst the disinfectants varied markedly. Two disinfectants were very effective (sensitivity of 80% and 60% respectively), three were moderate (30% sensitivity, each) and two were ineffective. Some of them were effective only at a concentration higher than that recommended by the manufacturer. For effective disinfection occasional sensitivity testing is therefore recommended.
