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.
