Abstract

CSOM is a disease of multiple aetiologias is well known for its persistence and recurrence in spite of treatment. Accordingly, the manifestations of CSOM are extremely variable and there may be any lesion from a small healed deformity of the tympanic membrane to a cholesteatoma infiltrating widely throughout the temporal bone. Aim: To study the phenotypic characterization and antimicrobial susceptibility pattern of Bacterial Isolates from cases of Chronic Suppurative Otitis Media. objectives: To study the Phenotypic characterization of bacterial isolates from clinically suspected cases of Chronic Suppurative Otitis Media. Anti-microbial susceptibility pattern of bacterial isolates from Chronic Suppurative Otitis Media. Methodology: sample collection -The ear discharge will collect using sterile cotton swabs with all aseptic precautions with the help of aural speculum and Collected samples will be transport in proper transport (Stuart transport medium) medium and process in the microbiology laboratory. And microscopy for gram positive and gramnegative bacteria and culture technique for morphology of bacteria and antimicrobial susceptibility test. Results A total 40 ear pus sample were proceeded from patient having clinically suspected CSOM Patients, attending NIMS university Hospital. Among them 19 (65.5%) were male and 10 (34.48%) female patients. Out of the 40 samples 29 (72.5%) samples were found to be significant bacteria and remaining 11 (27.5%) no growth.
