Introduction: Chronic Suppurative Otitis Media (CSOM) is a chronic and persistent inflammation of the mucosal lining of middle ear cleft which presents with recurrent ear discharge through a tympanic membrane perforation. CSOM is a worldwide disease and has higher prevalence in developing countries causing serious local damage and threatening complications.
Aim: To determine the profile of CSOM, its causative agents and their antibiotic susceptibility pattern.
Materials and Methods: The present study was a retrospective study in which data for culture and antimicrobial susceptibility profile of CSOM cases was retrieved from Microbiology department of Government Medical College, Kannauj, Uttar Pradesh, India, from January 2019 to October 2019 the analysis of data was done in February 2020. Two hundred pus swabs from discharging ears were processed during the study period for aerobic bacterial culture and antimicrobial susceptibility pattern in Microbiology department using standard microbiological techniques. The result analysis of the study was expressed as percentage and proportion for distribution of CSOM cases.
Results: Out of 200 patients, 114 (57%) were males and 86 (43%) females. Among the 200 cases, 147 (73.5%) cases showed growth and 53 (26.5%) showed no growth. The most common organism isolated in this study was Pseudomonas aeruginosa, 67 (42.40%) followed by Staphylococcus aureus. 48 (30.37%) and Klebsiella spp. 23 (14.55%). Gentamicin (85%) and amikacin (83%) had high level of antibacterial activity on all the isolates. Meropenem was found to be most effective drug for gram negative isolates. All Staphylococcus spp isolates were sensitive to vancomycin (100%).
Conclusion: Pseudomonas aeruginosa was the most predominant organism isolated in otitis media patients. Most of the isolates were sensitive to meropenem.
