چکیده
Background: Chronic supportive otitis media (CSOM) is one of the commonest illnesses in ENT practice. Thisstudy was conducted to find out the various aerobic microorganisms associated with CSOM and their currentantimicrobial susceptibility patterns to commonly used antimicrobials.Methods: samples were collected from 117 clinically diagnosed cases of CSOM and processed according tostandard protocols.Results: Out of 117 CSOM cases, 105 (86%) showed positive bacterial culture. The Staphylococcus aureus wasthe commonest aerobic isolate in CSOM. The sensitivity of Staphylococci spp. to commonly used antimicrobialsvaried from 27.2% for cefixime to 95.5% for gentamicin and coagulase positive. Pseudomonas isolates showedcomplete (100%) resistance to amoxicillin/clavulanate (co-amoxiclave), cloxacillin and cefixime, and high sensitivityto ciprofloxacin (95%) and cephalexin (90%).Conclusion: An appropriate knowledge of antibacterial susceptibility of microorganisms would contribute to arational antibiotic use and the success of treatment for chronic supportive otitis media.
