   Abstract

One hundred twenty patients with chronic suppurative otitis media (CSOM) in Basrah, 65 (54.2%) males and 55 (45.8%) females, with male: females ratio (1.2:1) and 60 individual without otological problems as control group were included in this study, which done during the period between March 2009 and January 2010. This includes the collection of aural swab samples, culturing of samples, identification of causative agent’s species and antibiotic sensitivity. Gram^’s negative bacteria were the commonest microorganism comprises (60%). Pseudomonas aeruginosa was common causative agent (19.04%), followed by Staphylococcus aureus (16.7%) and Klebsiella spp. (14.3%). Mixed infection was found in high percent (74%), in which P. aeruginosa and other microorganisms were more common. The antibiotic sensitivity pattern showed that P. aeruginosa was sensitive to Ciprofloxacin, amoxicillin +clavulanic acid and gentamicin, while other is appeared resistant, S. aureus was sensitive to ciprofloxacin, amoxicillin+clavulanic acid, erthomycin, cephalexine and it is resistant to penicillin and ampicillin, klebsiella species were sensitive to ciprofloxacin, amoxicillin +clavulanic acid, gentamicin, while resistant to tetracycline.

Key words: Pseudomonas aeruginosa, Staphylococcus aureus, Klebsiella spp., chronic suppurative otitis media, aural swab, antibiotic sensitivity, gram^’s negative bacteria, otological.
