This study determined the frequency and antibiogram of Salmonella species, Escherichia coli and Pseudomonas aeruginosa isolated from environmental samples. A total of 79 environmental samples of poultry origin including meat (n= 21), egg content (n= 16), drinking water (n= 7), feed (n= 7), egg shell (n= 16) and droppings (n= 12) were used for this study and bacteriologically analyzed by classical cultural methods. All isolated bacteria were identified using standard microbiological identification technique. The antimicrobial susceptibility profile of the isolates was determined by the Kirby-Bauer disk diffusion technique. Overall, 70 bacteria isolates comprising of Salmonella species (n=58), E. coli (n=10) and Pseudomonas species (n=2) were isolated from the samples of poultry origin; all of them were characterized as multidrug resistant. E. coli and Salmonella isolates were highly resistant to tetracycline, nalidixic acid, sulphamethoxazole-trimethoprim, nitrofurantoin and cefotaxime, while P. aeruginosa isolates were highly resistant to β-lactams used, tetracycline, tobramycin, nitrofurantoin and sulphamethoxazole-trimethoprim. On contrary, ofloxacin, imipenem and ertapenem were highly effective against examined bacterial pathogens. This study showed that poultry products harbor potential multidrug resistant bacteria which could cause diseases in humans, so, prompt and accurate detection of these pathogens is vital to the containment of their emergence and spread.
