Microbiological Assessment of Chronic SuppurativeOtitis Media

Abstract

Background : Chronic SuppurativeOtitis 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 suppurativeotits media and their antibiotic sensitivity patterns among our patients . Material and Methods : this descriptive study was carried out from 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 suppurativeotits media attending the out patients clinic were included in the study , pus sample were collected from the discharging ears and sent to microbiological department.Results :- from 100 specimens there were 90 (90%) bacterial isolates and 10 (10%) fungi .Pseudomonas aerugenosa 40 (40%) was the dominant isolate followed by Staphylocooccusaureus 19 (19%) and Proteus spp. 15 (15%) . Antibiotic sensitivity pattern of Pseudomonas aerugenosa showed that imipenem was active in 100% and Vancomycin was active in 100% of Staphylococcus aureus isolate .Conclusion :- Pseudomonas aerugenosa is the most common isolates followed by Staph . aureus from the cutluer specimens of chronicsuppurativeotits media . Pseudomonas aerugenosa is increasingly becoming more resistant to the commonly used antibioltic like cephalosporine Amoxicillin & Ampicillin .Recommendation:We advise to do culture and sensitivity test for every patient with chronic suppurativeotits media (CSOM)and to describe systemic antibiotics according to the result of this test .
