Microbiological Assessment of Chronic Suppurative Otitis Media

Abstract

Background: Chronic Suppurative Otitis Media is a common infectious disease. the microorganisms commonly associated with and their antibiotic sensitivity patterns is important for its treatment.

Objectives: to study the microorganisms associated with chronic suppurative otitis media and their antibiotic sensitivity patterns among our patients.

Methodology: this descriptive study was carried out in January 2012 to December 2012 at ENT Department and microbiology department . of AL-Hakeem general hospital in Najaf city. A total of 100 patients with unilateral and bilateral active chronic suppurative otitis media attending the out patients clinic were included in the study, pus sample were collected of the discharging ears and sent to microbiological department .

Results: of 100 specimens there were 90 (90%) bacterial isolates and 10 (10%) fungi. Pseudomonas aeruginosa 40 (40%) was the dominant isolate followed by Staphylococcus aureus 19 (19%) and Proteus spp. 15 (15%) . Antibiotic sensitivity pattern of Pseudomonas aeruginosa showed that imipenem was active in 100% and Vancomycin was active in 100% of Staphylococcus aureus isolate .

Conclusion: Pseudomonas aeruginosa is the most common isolates followed by Staph. aureus in the culture specimens of chronic suppurative otitis media. Pseudomonas aeruginosa is increasingly becoming more resistant to the commonly used antibiotic like cephalosporine Amoxicillin & Ampicillin.

Recommendation: We advise to do culture and sensitivity test for every patient with chronic suppurative otitis media (CSOM) and to describe systemic antibiotics according to the result of this test.
