Abstract:
This is a descriptive study conducted in the Research Laboratory, Sudan University
of Science and Technology in the period from February to March 2011. The aim of
the study was to determine frequency of and susceptibility pattern of
Staphylococcus aureus among patients with otitis media in Khartoum State. One
hundred ear swabs were collected from patients with different ages and sexes
suffering from ear discharge, the isolates were identified by morphological
characteristics on culture and biochemical tests. And antimicrobial sensitivity was
performed in vitro by disc diffusion method. The results revealed that,
27%Staphylococcus species (15 % S.aureus and 12% S.epidermidis), 53% other
bacteria and 20% no growth. S. aureus was sensitive to vancomycin (100%), then
ciprofloxacin (93%), amikacin (86%), methicillin (86%) and oxacillin (86%),
norfloxacin (80%), cefuroxime (66%), co-trimoxazole (46%). Otitis media caused
by S. aureus constitute a significant and a major health problem, affects children
mainly and less common in adults. Further investigations are needed to study the
etiology of otitis media and the resistance to antimicrobial agents.
