Abstract
OBJECTIVE: To understand bacteriology of chronic suppurative otitis media (CSOM) and drug sensitivity of isolated bacteria for better treatment of CSOM. METHOD: Secretions of 92 samples with chronic suppurative otitis media were collected and cultured for aerobic and anaerobic bacteria respectively. Drug sensitivity test of isolated bacteria was done. RESULT: Aerobic bacteria was found in 75 of 92 samples (81.5%), the main pathogens were pseudomonas aeruginosa, aureus staphylococcus and bacillus proteus, and their sensitive rates for ciprofloxacin were 89.0%, 88.2% and 85.0% respectively. Anaerobic bacteria was found in 10 samples (10.9%) and the relative sensitive drug was cefoperazone sodium. CONCLUSION: Pseudomonas aeruginosa, aureus staphylococcus and bacillus proteus are the main pathogens of chronic suppurative otitis media, and their sensitive rates for ciprofloxacin are high.
