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.
