MICROBIAL CAUSES OF OTITIS MEDIA IN SUDANESE PATIENTS

Abstract

This descriptive study was conducted in Khartoum State at E.N.T Hospital, Out-patient Clinic, in the period, from April 2001 to March 2002. The aim of the study was to see the prevalence of the different aerobic bacteria causing otitis media in Khartoum. The required data was collected through questionnaire and laboratory cultures were used as a tool of investigation. Fifty ear swabs samples were randomly collected in the study from different patients of different ages and sexes. Samples were collected from patients with ear discharge, and the study revealed that, Staphylococcus species were responsible for infections in otitis media (31.4%), Proteus species (23.0%), Streptococcus species (14.4%), Pseudomonas species (11.4%), E. coli (11.4%), Klebsiella species (2.8%), Providencia Species (2.8%) Morganella morganii (2.8%) of the cases. In vitro sensitivity test: on all isolated organisms was performed for the different types of antimicrobial agents. Most Staphylococcus species were sensitive to gentamicin, norfloxacin and ciprofloxacin respectively, and resistant to ampicillin, sulphatriad, colistin sulphate, co- trimoxazole, tetracycline, cephalothin, streptomycin. Proteus species were sensitive to gentamicin, ciprofloxacin, norfloxacin, cefixime (suprax), respectively, and resistant to ampicillin, tetracycline, cephalothin, co-trimoxazole, sulphatriad, colistin sulphate, streptomycin, and ceftriaxone. Most of the other isolates in this study were sensitive to gentamicin, least sensitive to co-trimoxazole, and resistant to ampicillin, tetracycline and streptomycin.
