Study of Aerobic Bacterial Profile in Chronic Suppurative Otitis Media and their Antibiotic Susceptibility Pattern

Abstract

INTRODUCTION: Hearing is one of the most important senses of man which provides him with the ability to perceive the world and also helps him in communication.Chronic suppurative otitis media (CSOM),a tremendous health predicament since time immemorial, is a chronic inflammation of the middle ear cleft which may lead to serious sequelae and complications. The wide spread use of antibiotics has precipitated the emergence of multiple resistant strains of bacteria which can produce both primary and postoperative infections. MATERIALS AND METHODS: This is a Prospective studyconducted at Department of Microbiology, Tertiary care teaching hospitalover a period of 1 year with200 samples were collected from patients attendingat out Patient department of ENT included in the study.After cleaning the external ear with alcohol, ear discharge is collected aided by a Bull lamp and aural speculum with absorbable sterile cotton swabs under strict aseptic precaution. RESULTS: Analysis of these cases of CSOM in both sexes and age groups as shown in Table - 1: revealed that the majority of cases of CSOM were in the age 11-20yrs in both sexes .The overall incidence of CSOM was found to be more in males 117 than in females 83 and this predominance was noted in all the age groups.The details of anaerobic organisms isolated in csom cases.Bacteroidsfragilis is the predominant organism followed by peptosteptococcus.All anaerobes were 100% sensitive to Metronidazole. CONCLUSION:Out of 200 samples 14 anaerobic organisms were isolated of which Bacteroidesfragilis 4(28.6%) were predominant anaerobes followed by Peptostreptococcus species 3(21.4%).This sudy is designed to have the knowledge of the pathogens and antibiotic sensitivity pattern responsible for CSOM and choosing suitable antibiotics according to susceptibility tests should guide the management of disease treatment and reduce the recurrence and complications of CSOM.
