Multi-antibiotic resistant strains of bacteria represent a global medical challenge, having reduced or threatened to completely eliminate the list of reserved, last-resort agents usually deployed in serious and/or life-threatening infections. Even newer and very potent antibiotics are not spared from the emergence of resistant strains of organisms. In this study, the antibiotic resistance profile and the plasmid profile of some multi-antibiotic resistant bacteria strains isolated from the urine samples of fifty volunteers (ages 15-30) from a community in south eastern Nigeria were analyzed. Eight multidrug-resistant bacteria were isolated from the 50 urine samples, of which approximately 60% showed resistance to nitrofurantion, amoxicillin, ciprofloxacin, ampicillin, gentamicin, ampiclox and erythromycin. The MIC of the isolated S. aureus, E. coli, and Klebsiella species to ofloxacin, ciprofloxacin, pefloxacin, and co-trimoxazole were greater than 500 μg/ml. Plasmid profile studies revealed the presence of R-plasmids of size range 11-18 kb. The cultures of resistant isolates irreversibly lost their antibiotic resistance with acridine orange and SDS treatment, which suggests that the resistant genes could be harboured in the plasmids.
