A total of eighteen Pseudomonas aeruginosa isolated from CMH Muzaffarabad, were screened for their resistance to the antibiotics, Ampicillin, Chloramphenicol, Doxycycline, Erythromycin, Gentamicin, Kanamycin, Minocycline, Nalidixic acid, Penicillin, Streptomycin, Urixin and Velosef. Generally, the isolates showed the highest frequency of resistance to Penicillin and lowest to Velosef, followed by Doxycycline and Erythromycin. The resistant isolates showed eight patterns of antibiotics resistance at a level as high as 1000 µg/ml. Some of the antibiotic determinants were cured by acridine orange treatment, indicating the widespread antibiotic resistance is mediated through plasmids among Pseudomonas aeruginosa.
