AIMS: Chronic suppurative otitis media (CSOM) is a common infectious chronic ear disease in India resulting in serious complications, especially hearing impairment. Irrational use of antibiotics for its management has led to the emergence of multidrug-resistant bacterial strains. Considering this, this study was conducted to know the pattern of causative organisms associated with CSOM and their antimicrobial sensitivity. Materials and Methods: Ear discharge from 200 clinically diagnosed cases of CSOM was collected by suction using sterile techniques in a sterilised test tube on wash bottle principle consisting of a glass tube made air tight with the help of a cork with an inlet and outlet facility. All samples were processed in the department of microbiology for the identification of bacterial and fungal isolates and their antimicrobial sensitivity testing. Results: Among the 200 samples of ear discharge, 127 were from ear having tubotympanic (mucosal or safe) type of CSOM while 73 were from ear with attico-antral (squamosal or unsafe) CSOM. Among aerobic isolates, Pseudomonas aeruginosa (35%) was most common followed by Staphylococcus aureus. Other aerobes isolated were Klebsiella spp., coagulase-negative Staphylococcus, Proteus spp. and Escherichia coli. Fungus was isolated in tubotympanic (9.45%) CSOM only. Among anaerobic isolates, Peptostreptococcus (1%) was most common. Conclusion: Monomicrobial isolates, especially P. aeruginosa and Staphylococcus species, were found to be most common in our study. Therefore, evaluation of microbiological pattern and their antibiotic sensitivity pattern in local area becomes helpful in prescribing empirical antibiotics for successful treatment of CSOM.
