Abstract: 

Objective: To determine the most common microorganisms causing chronic suppurative otitis media (CSOM) and their antibiotic sensitivity. Methods: A 111 patients with otic secretion (purulent discharge), The samples were taken by swab from the external meatus through the tympanic perforation under microscopic conditions. All specimen were cultured for aerobic and anaerobic conditions. Results: A total of 165 isolates were obtained, 151 (91.5%) were bacterial and 14 (8.5%) were fungi. The major organisms isolated were Pseudomonas aeruginosa 47 (28.5%); followed by Staphylococcus aureus 30 (18.3%); Proteus mirabilis 23 (14%); Providencia stuartti, 11 (6.7%); Bacteroids melaninogenicus, Aspergillus sp., candida sp., 7 (4.2%) each; and other microorganisms will be presented in (3-0.6%). The antibiotic resistance of Pseudomonas aeruginosa, was (59.2%) to Gentamicin; (35.9%) to carbenicillin; (23.8%) to amikacin; (13.8%) to ceftazidime; (6%) to ciprofloxacin; The resistance of Staphylococcus aureus was (72.7%) to penicillin; (28.6%) to erythromycin; (18.2%) to cephalothin; (8.3%) to cloxacillin; (3.8%) to ciprofloxacin; (0%) to vancomycin. The resistance of Proteus mirabilis was (55.6%) to ampicillin; (47%) to carbencillin; (29%) to cephalothin (14%) to gentamicin; (4.8%) to amikacin; (0%) to ciprofloxacin.
