Bacteriology Of Chronic Suppurative Otitis Media Study Of Aerobic Bacteria

Abstract

Fifty ear swabs were collected from patients suffering from chronic suppurative otitis media (CSOM) and attended the out patients of Khartoum Ear, Nose, and Throat Teaching Hospital, and the Ear, Nose, and Throat Department of Omdurman Teaching Hospital, between December 2004 to March 2005. All the samples were subjected to bacteriological examination to identify the causative agent of the disease. The isolated microorganisms were subjected to antimicrobial sensitivity tests using different antibiotics. Various types of microorganisms were isolated. The common causative agents were Pseudomonas species 30.8%, Staphylococcus species 23.1%, Proteus mirabilis 17.4% , and Klebsiella species 9.7% . From the sensitivity tests, most strains were sensitive to ciprofloxacin (94.2%), in contrast they were highly resistant to penicillin (15.4%), and ampicillin (30.8%). Furthermore the prevalence of the disease was more common in children than its occurrence in adults.
