Aims: The present study was aimed to identify the bacterial isolates causing chronic suppurative otitis media (CSOM) and to study their antimicrobial susceptibility pattern. Subjects and Methods : Totally, 120 patients of CSOM complaining of ear discharge were included in the study. Aural swabs were taken and sent immediately to the microbiology laboratory and processed. Bacterial isolates were identified using standard methods, and antibiotic susceptibility testing was done. Results: In the present study, from 120 cases of tubo-tympanic type of CSOM, majority that is, 82 (63.56%) were Gram-negative; Pseudomonas sp. 48 (37.21%) were the most common bacteria isolated followed by Staphylococcus aureus 32 (24.81%). Among Pseudomonas aeruginosa, the most common isolated bacteria, meropenem has the highest susceptibility rate (97.91%); among S. aureus, vancomycin has the highest susceptibility rate (100%). Conclusions: Pseudomonas sp. and S. aureus were found to be the common cause of CSOM in the present study. These organisms are found to be less susceptible to the routinely used drugs such as quinolones and aminoglycosides and also the resistance pattern of the micro-organisms usually keeps changing. Hence, judicial use of antibiotics is recommended.
