title: Incidence of pathogenic microorganisms in clinical specimens from hospitals in south-western Nigeria.
abstract: The pattern and frequency of bacterial isolates cultured from 687 clinical specimens from four University teaching hospitals in South Western Nigeria were determined. A total of 707 bacterial isolates were cultured from 18 different clinical sources giving an average of 1.03 bacteria per sample identified in this collection. Of these, gram negative rods constituted 78.1% and the rest were staphylococci. The most common organism isolated in urine samples was E. coli (32.1%) whilst S. aureus (28.9%) was the most frequently isolated organism from wounds. An interesting observation was the significant occurrence of Aeromonas hydrophilia and Klebsiella pneumoniae in urine samples.
