Abstract
Objective: To determine the frequency of different bacterial pathogens in patients with active chronic mucosal otitis media with antibiotic susceptibility in outpatients.
Methodology: This prospective cross-sectional study was conducted at the Ear, Nose, and Throat (ENT) Department, Pakistan Railways Hospital, Rawalpindi, from July/2025 to Dec/2025. After obtaining written informed consent, 76 patients were enrolled. Middle ear purulent discharge was collected and cultured, and the isolated bacteria's antibiotic susceptibility was assessed.
Results: The median age of the patients was 35.5±16.3 years. The commonest pathogen found was Staphylococcus aureus in 35 (46.1%), Pseudomonas aeruginosa in 14 (18.4%) patients, and coagulase-negative Staphylococcus in 8 (10.5%). S. aureus was highly sensitive to vancomycin (100%), gentamicin (97.5%), rifampicin (97.5%), and sulfamethoxazole/trimethoprim (97.5%) and was resistant to penicillin (57.5%). P. aeruginosa was highly sensitive to piperacillin (100%), meropenem (100%), and piperacillin/tazobactam (100%) and was resistant to ceftriaxone and ciprofloxacin.
Conclusion: Pseudomonas aeruginosa and Staphylococcus aureus were the most often detected bacteria in patients with chronic active mucosal otitis media. Common medications were found to be ineffective against most of the isolates.

Key words: CSOM, bacterial pathogens, antimicrobial resistance.
