Abstract : Objective – To study the bacterial and fungal organisms present in chronic suppurative otitis media and to study the antibiotic sensitivity pattern of the bacterial isolates.Methodology – A total number of 100 patients with clinical diagnosis of CSOM, attending the ENT OP comprised the study group. Three pus swabs from each patient discharging ear were collected. One pus swab is used for smear preparation, second swab for bacterial cultures and third swab for fungal cultures.Bacterial isolates identified and antibiotic susceptibility testing is done.Fungal isolates were identified by conventional methods.The findings were analysed.Results – Out of 100 patients, 53% were females and 47% were males. In this 40% belonged to 0-15 yrs age group. From 100 bacterial cultures 95 bacterial strains were isolated. In this Pseudomonas aeruginosa ( 36 ), Klebsiella(20),Staphylococcus aureus(10) followed by other organisms. Different fungal organisms isolated from 100 cultures were Candida albicans(12),Aspergillus  flavus(5), Aspergillus niger(4). Study of antibiotic susceptibility of 95 bacterial isolates revealed that Imipenem is most effective without resistance followed by Amikacin(6.3% resistance), Gentamicin(7.3%),Ciprofloxicin(10.5%) followed by other antibiotics.Conclusion – The present study stresses the need for careful isolation of both bacterial and fungal organisms to establish the role of fungi in CSOM pathology and to prevent administration of unwanted antibiotics.
