Infection of Pseudomonas aeruginosa has been responsible for economic losses in younger birds. This research was designed to report and document multidrug resistant P. aeruginosa recovered from chicken during infection. Sixty-seven freshly dead chicken were used in this research, the trachea, the liver, and the heart were targeted for P. aeruginosa isolation. The isolates were identified based on the cultural, morphological, and biochemical characteristics. Antimicrobial test was carried out on the pure isolates using the disc diffusion method. A total of 23 isolates of P. aeruginosa were recovered; 19 isolates were recovered from the trachea, 3 from the liver and 1 from the heart. All the isolates were showing green pigment on nutrient agar, they were all Gram-negative rods, motile, catalase and citrate positive. The result of the antibiotic susceptibility showed that ampicillin was most resisted with a resistance of 95.7% (22) while gentamicin was least resisted with 39.1% (9), and 69.5% (16) of the isolates were showing resistance to more than three antibiotics. The most encountered resistant pattern was AMP, TLY with 87%. The result from this study revealed that multidrug resistant P. aeruginosa in poultry may be emerging and serving as a reservoir for resistant P. aeruginosa gene.
