Antibiotic resistance bacteria pathogens especially in food animal is an emerging problem of public health concern, resistant pathogens is acquired by man through food chain. This study aimed at investigating antibiotic resistance pattern of pathogenic bacteria in poultry droppings. Samples of fresh poultry dung were obtained from free-range chicken and nine commercial chicken farms, in Akure, Ondo State, Nigeria. Samples were plated on selective and differential media. Isolated bacteria were identified by standard microbiological method. Pathogens isolated include both Gram positive and Gram negative bacteria, namely; Escherichia coli, Enterobacter aerogenes, Klebsiella spp. Citrobacter spp. Salmonella spp. Serratia marcescens, Shigella dysenteriae, Proteus spp, Pseudomonas aeruginosa, Staphylococcus aureus and Micrococcus luteus. Antibiotic susceptibility testing was carried out using the disk diffusion technique. Antibiotics used for gram negative pathogens were; ofloxacin, amoxycillin, tetracycline, gentamycin, augmentin, ceftriazone, nitrofuration, cotrimozazole, ciprofloxacin and chloramphenicol while cotrimoxazole, erythromycin, augumentin, chloramphenicol, tetracycline, cloxacilin, gentamycin, streptomycin were used for gram positive pathogens. The resistant pattern in gram negative pathogens revealed that more than 90% were resistant to Augmentin, Ceftriaxone, Nitrofuratoin, Amoxicillin and Cotrimoxazole, 80.15% resistant to tetracycline, 83.97% resistant to chloramphenicol, 35.11% resistant to gentamycin, 16.79% resistant to ciprofloxacin and 8.40% resistant to ofloxacin, gram positive pathogens were 100% sensitive to streptomycin and 100% resistant to cotrimozazole and augmentin, 83.33% resistant to tetracycline, 38.89% resistant to cloxacilin and 22.22% resistant to gentamycin, erythromycin and chloramphenicol. Conclusively, the conventional use of antibiotics in poultry has resulted to the emergence of antibiotic resistant pathogenic bacteria.
