Microbiological assessment of chronic suppurative otitis media

الملخص EN

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 otits 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 suppurative otits 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.
