Abstract
Chronic Suppurative Otitis Media (CSOM) is defined as chronic inflammation of middle ear and mastoid cavity, which presents with recurrent ear discharge or otorrhoea through tympanic perforation. The indiscriminate and haphazard use of antibiotic along with poor compliance and follow-up of these patients has resulted in the emergence of multiple resistant strains of bacteria and the persistence of low grade infections. Present study was conducted to know the bacteriological and fungal profile in CSOM cases and to categorize the various organisms isolated and evaluate their antibiotic sensitivity pattern. A total of 149 isolates were obtained from 132 samples, out of which 133 (89.26%) were aerobic bacteria while 16 (10.73%) were fungal isolates. Out of the 133 bacterial isolates, the most common organism isolated was Pseudomonas aeruginosa 46 (34.58%), followed by Staphylococcus aureus 27 (20.30%). Other organisms isolated were Proteus mirabilis, Klebsiella pneumoniae, Escherichia coli, Acinetobacter spp., coagulase negative Staphylococci, Enterobacter spp., Citrobacter freundii and Serratia marcescens. Overall sensitivity of gram negative bacteria was more towards Amikacin, Ceftriaxone, Ciprofloxacin and Imipenem. Most of the Gram positive isolates were sensitive to Clindamycin, Erythromycin and Tetracycline and Linezolid. Fungal isolates were Aspergillus niger, Aspergillus flavus, Candida albicans and non-albicans Candida.
