Abstract:

Chronic suppurative otitis media (CSOM) is one of the major causes of deafness in India. The chronicity of the disease and poor response to routine antimicrobials prompted us to isolate and identify the causative organisms and study antimicrobial susceptibility pattern. The ear discharge was collected using two sterile cotton swabs. One swab was used for performing Gram’s stain and KOH mount. The second swab was used to inoculate Blood agar, MacConkey agar and Sabouraud Dextrose agar (SDA) for the isolation of aerobic bacteria and fungal pathogens. The antibiotic susceptibility testing of the bacterial isolates was done by Kirby Bauer’s Disc Diffusion method according to CLSI Guidelines. Among 104 samples included in the study, Single bacterial growth was obtained in 69 (66.3%) samples and single fungal growth was seen in 24 (23.1%) samples. Mixed growth was seen in 6 (5.8%) samples and no growth was observed in 5 (4.8%) samples. Among the bacteria Pseudomonas aeruginosa (30.5%) was the predominant isolate and Aspergillus niger (8.6%) was the predominant isolate among fungi. Majority of the Gram negative isolates were sensitive to imipenem and all the Staphylococci isolates were sensitive to vancomycin, teicoplanin and linezolid. Periodic monitoring of microbiological profile is essential for the effective management of CSOM cases in a particular geographical area.
