Abstract :

Chronic Suppurative Otitis Media (CSOM) is a chronic inflammation of the middle ear and mastoid cavity. India is one of the countries with highest CSOM prevalence. Hence, the present study was undertaken to analyse the common presenting symptoms and risk factors and to isolate the aerobic bacterial and fungal pathogens associated with CSOM. The antibiotic susceptibility pattern and ESBL production of the bacterial isolates was also studied. The study included 70 patients of age 0-80 years with discharging ears for more than 3 months who were admitted or visited the ENT outpatient department. Swabs from ear discharge were obtained and streaked in Nutrient, MacConkey and blood agar plates and antibiotic sensitivity testing was done. The most common bacterial isolate was Pseudomonas sps (30.18%) and the most effective antibiotic was Amikacin. ESBL producers accounted for 16.3%. Aspergillus niger and Candida species were the fungi involved. The high rate of multiple drug resistance, particularly to cheap and frequently used antibiotics, raises serious concern.
