Abstract
This study assessed the biosecurity and other preventive measures carried out on poultry farms. Deep litter system of management was commonly practiced and there was report of multiple antibiotics usage in feed. There was low level of biosecurity in most of the farms surveyed. A total of 3820 pooled egg, 114 cloacal and 140 ovarian follicle samples were tested for Salmonella. Salmonella was not isolated in any of the samples. Other organisms were isolated such as Serratia plymuthica, Enterobacter agglomerans, and Serratia liquefaciens. Also 100 pooled egg samples were analyzed for total aerobic counts, total coliform counts and Escherichia coli. Of the 100 pools, 3 were positive for E. coli for which antimicrobial susceptibility patterns were tested using a panel of 12 antimicrobial agents. There was no significant difference (P > 0.05) in the mean total aerobic counts and coliform counts. There was a negative correlation of the total aerobic and coliform counts (r = -0.028), total aerobic counts and antibiotics usage (r = -0.05472) as well as correlation of coliform counts and antibiotics use (r = -0.187). The bacterial isolates were resistant to multiple antibiotics.
