Abstract: Background: Chronic suppurative otitis media (CSOM) is one of the most common infections and a major health issue in developing countries causing serious complications. Early and effective treatment based on the microbial pattern and appropriate antimicrobial agents ensures prompt recovery and prevents dreaded complications. The present study aims to isolate the organisms associated with mucosal type of CSOM and to detect the antibiogram of the isolates. Materials & Methods: Samples were taken from 202 patients over a period of one year from mucosal type of CSOM patients. Gram staining, KOH mount, biochemical tests & culture sensitivity by modified Kirby Bauer disc diffusion method were carried out for identification and antibiotic susceptibility. Results: The most common organisms isolated were Staphylococcus aureus (49.6%) and Pseudomonas aeruginosa (19.7%). Fungi accounted for 20.3% while 10.4% were anerobes. Antibiotic susceptibility revealed maximum sensitivity to Amikacin (83.3%), gentamicin (80%) and ceftriaxone (71%). Conclusion: Proper knowledge of the causative organisms and their antibiotic susceptibility is of utmost importance in the effective treatment, thereby preventing complications and antibiotic resistance and reducing the economic burden on the care seekers.
