Objective: Otitis media is associated with severe complications like mastoiditis, meningitis and hearing loss, if left untreated. The study was designed to determine the prevalent bacteria responsible for otitis media and to determine their antibiotic susceptibility pattern.
Methodology: Pus samples were collected from patients suffering from middle ear infections. Ear swabs were examined by standard microbiological techniques followed by antibiotic susceptibility testing.
Results: Among 91 samples collected over period of nine months, Staphylocuccus aureus was isolated in highest number (47%), followed by Pseudomonas aeruginosa (34%). Staph aureus isolates showed high susceptibility to linezolid (93%) followed by tigecycline, doxycycline, chloramphenicol, amikacin and gentamicin. Pseudomonas aeruginosa isolates showed high susceptibility to imipenem, meropenem, ciprofloxacin and piperacillin-tazobactam.
Conclusion: Staphylocuccus aureus was isolated in highest number followed by Pseudomonas aeruginosa. Staph aureus showed high susceptibility to linezolid and Ps aeruginosa showed high susceptibility to imipenem.
Key words: Otitis media, staphylococcus, pseudomonas.
