Antibiotic Susceptibility of Bacterial Pathogens Associated With Otitis Media Among Patients in Specialist Hospital Sokoto

Abstract

A total of 120 ear swab samples were examined from patients of different age groups attending Specialist Hospital, Sokoto, with ear infection. The swab samples were cultured on Chocolate agar, Blood agar and MacConkey agar media. Identification of the isolated bacteria was carried out using standard biochemical tests. The results show an overall infection rate of76.68% (92 out of l20).And the age group mostly affected is the 0-5 years with infection rate of 54.17%. The results of the identification showed the following bacteria in decreasing order of prevalence as Staphylococcus aureus 30 (30.61 %), Pseudomonas aeruginosa 17 (17.35%), Proteus mirabilis 16 (16.33%), Citrobacter freundii 14 (14.29%), Escherichia coli 6 (6.12%), Serratia mercescens 6 (6.12%), Staphylococcus albus 5(5.10%) and Enterobacter species 4(4.08%). Antibiotic Sensitivity test was carried out. The results indicated that Ciprofloxacin (10Ilg), Tarivid (IOug) and Levofloxacin (Sug) are the best antibiotics with mean zones of inhibitions of 1O.70mm, 12.25mm and 12.25mm respectively, whereas Ampicillin (25Ilg)(4.00mm) Cotrimoxazole (25Ilg) (O.OOmm) and Tetracycline (Iuug) (1.63mm) did not show promising result.
