Abstract


There is no doubt that antibacterial agents have saved the human race as well as animals from death and suffering due to bacterial diseases. However, bacterial resistance is a major threat from these agents. The aims of this study were to investigate pattern of antibacterial use in poultry, and the level of resistance by common bacterial agents of economic importance in Nigeria. Pattern of antibacterial use in poultry practice in North-Central and South-West Nigeria were obtain through 150 questionnaires administered to practicing veterinarians, animal health workers and poultry farmers. Again, the level of antibacterial resistance was investigated employing laboratory results from three renowned veterinary diagnostic laboratories in the country where the rate of sensitivity as well as resistance was obtained. Among the commonly used antibiotics in poultry practice, doxycycline and oxytetracycline were the most frequently prescribed for chickens infected by common bacteria organisms. Well over 50% of the treatments with different antibiotics did not follow the specifications, including dosage regimen. Over 50% of Salmonella spp, Pasteurella spp, Haemophilus spp, Mycoplasma spp, and Escherichia coli clinical isolates from poultry were resistant to the commonly used antibacterial agents. The observed inappropriate use of antibacterial agents in poultry explains the high prevalence of antibacterial resistance to common antibacterial agents. Therefore, judicious antibacterial use in poultry practice is imperative in order to circumvent emergence of resistant bacteria organisms, public health implications, and economic losses in poultry production.
