Abstract
This study determined the susceptibility pattern and multiple antibiotic resistance (MAR) index of 92 Pseudomonas aeruginosa strains from clinical samples comprising mainly urine (51.1%) and wounds (41.3%) obtained from the surgical units of Ahmadu Bello University Teaching Hospital, Zaria, Nigeria; over a 24-month period. The strains were susceptible to imipenem (94.6%), ciprofloxacin (90.2%), amikacin (89.1%) and ceftazidime (78.3%) but resistant to ofloxacin (82.6%), perfloxacin (58.7%) and gentamicin (35.8%). Analysis of the MAR index of isolates revealed that 60.9% had MAR index of 0.3 and above, which is an indication of probable origin from the hospital environment where antibiotics are extensively used. A strict management of antibiotic policies and a continuous surveillance programme for multidrug resistant pathogens like P. aeruginosa in specialised units is advocated.
