ABSTRACT
An antibiotic is a type of antimicrobial substance active against bacteria. It is the most important type of antibacterial agent for fighting bacterial infections, and antibiotic medications are widely used in the treatment and prevention of such infections. Antibiotics come in hundreds of different varieties, but the majority of them fall into one of six categories: penicillin, cephalosporins, aminoglycosides, tetracycline, macrolides, fluoroquinolones. The aim of this study was to evaluate the antibiotic resistance patterns of bacteria from poultry droppings. In this study, eight (8) samples which were collected from different poultry farms were analyzed for the bacteria present and screened for their antibiotic resistance pattern. The mean heterotrophic count of the poultry droppings ranged from 1.69×106 to 10.1×106 cfu/ml. The results obtained revealed that the poultry droppings harboured various bacteria isolates which include Serratia marcescens, Pseudomonas syringae, Proteus mirabilis and Salmonella sp. The antibiotic susceptibility result indicated a high level of resistance of the various identified isolates to some of the antibiotics. From the antibiotic sensitivity test, it indicated that there was a high resistance to CIP(ciprofoxacin),ERY(erythromycin),GEN(gentamicin),CS(colistin),CD(clindamycin) by majority of the microorganisms isolated. From this study, microorganisms present in poultry droppings can be pathogenic and cause diseases . Proper diagnosis must always be carried out to ensure that the right antibiotics are prescribed because overuse of antibiotics would lead to formation of resistant strains of the causative microorganism.
