Bacteriological Profile of Chronic Suppurative Otitis Media.

Background: Chronic Suppurative Otitis Media (CSOM) is major health problem throughout the world in poor socioeconomic conditions as well as in developing countries including India. CSOM is infection of middle ear cleft leading to dangerous complication like brain abscess and meningitis. Aim: This study was conducted to know the bacterial etiology of CSOM and to detect the antimicrobial sensitivity of isolates. Material and Methods: In our study, 48 aural swabs of patients with CSOM from patients attending Department of Otorhinolaryngology, Bharati Hospital, Pune were collected and processed at Department of Microbiology, Bharati Vidyapeeth Medical College, Pune between June 2014 and September 2014. Isolation and identification of isolates was performed using standard microbiological techniques. Antibiotic sensitivity testing was done using Kirby Bauer disc diffusion method as per CLSI guidelines. Results: In our study, 83.33 % samples showed growth. We observed that, number of female patients was more than number of male patients. Maximum patients were seen in age group 3140 years. Predominant organism isolated was Pseudomonas aeruginosa followed by Staphylococcus aureus, Klebsiella pneumoniae and Proteus mirabilis. Pseudomonas aeruginosa and other gram negative isolates were highly susceptible to Piperacillin + Tazobactam, Imipenem, Polymyxin-B. Staphylococcus aureus was highly sensitive to Vancomycin, Teicoplanin, Linezolid and Chloramphenicol.
