Abstract

The prevalence of selected pathogens in four hundred and ninety eight
samples of ear, wound swabs and urine samples submitted to the
Microbiological Laboratory of Wesley Guild Hospital, Ilesa, Nigeria was
investigated. In ear infections, Pseudomonas aeruginosa predominated
(50%), followed by Staphylococcus aureus (30%) and others (20%). In
wound swabs, S. aureus predominated (46.3%), P. aeruginosa(16%).
Other bacteria isolated included Klebsiella spp, Proteus spp and
Escherichia coli accounting for 18%. In urine, S. aureus and E. coli were
more frequently isolated with 49% and 23% respectfully. The
antibiogram studies showed that P. aeruginosa, was highly sensitive to
Ciprotab, Perflotab and Gentamycin except Pseudomonas isolates from
wounds which were resistant to Gentamycin. The isolates were resistant
to Streptomycin, Ampicillin and Cotrimoxazole (septrin). Citrus juice –
C. aurantifolia (Lime) and C. limon (Lemon) on P. aeruginosa gave
positive results with lethal effects on the test organisms with zones of
inhibition ranging from 7mm-22mm in diameter around the colonies.
