ABSTRACT
Pseudomonas aeruginosa is a gram-negative, rod-shaped, asporogenous, and monoflagellated bacterium. It is an obligate aerobic organism capable of optimal metabolism in the presence of oxygen although can also respire anaerobically on nitrate or other alternative electron acceptors. This study was carried out to investigate the antibiotics resistance pattern of Pseudomonas aeruginosa isolates from clinical or environmental and animals (cow dung and poultry dung) samples. The isolates were identified using the standard cultural, morphology and biochemical characteristics. The antibiotics susceptibility test was performed by the disc diffusion method according to NCCLS (National committee for clinical and laboratory standard) guidelines. The zones of inhibition of Pseudomonas aeruginosa was highest in clinical(swab) samples which is 24% were resistance to streptomycin, perfloxacin, augmentin, septrin followed by cow dung which is 20% and it was observed to be highly resistance to chloranphenicol, streptomycin, amoxacillin, septrin. The least was observed in poultry dung 18% which was highly resistant to chloranphenicol, pefloxacin, augmentin. The reason for studying the resistance pattern of Pseudomonas aeruginosa, is to counteract emerging resistance pattern from different source.
