[The clinical investigation of bacteriology of chronic suppurative otitis media].

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.
