Abstract :

Background: Chronic suppurative otitis media (CSOM) is a persistent, insidious ,notorious infection and a major health problem in developing countries causing serious local damage and threatening complications. The situation is complicated by the increasing antibiotic resistance these days. Early and effective treatment based on the knowledge of causative micro-organisms and their antimicrobial sensitivity ensures prompt clinical recovery and possible complications can thus be avoided.Aims and objectives: To isolate the aerobic bacteria associated with CSOM and to detect the antibiogram of the iolates. Materials and Methods:A total of 175 patients clinically diagnosed of CSOM were enrolled in the study and the samples were obtained from each patient using sterile cotton swabs and cultured for microbial flora. Drug susceptibility testing for aerobic isolates was conducted using Kirby-Bauer disc diffusion method. Results:The most common causative organisms isolated were Staphylococcus aureus (42.63%) and Pseudomonas aeruginosa (22. 63%) amongst the 190 aerobic isolates. Antimicrobial profile of aerobic isolates revealed maximum sensitivity to gentamicin followed by ciprofloxacin . Conclusion: Knowing the etiological agents of CSOM and their antimicrobial susceptibility is of essential importance for an efficient treatment, prevention of both complications and development of antibiotic resistance and finally for reduction of the treatment costs.
