Abstract:
Normal flora of eye differs in population based on geographical location and occupation. The present study aimed at determining normal flora of eye in healthy individuals. This was a cross sectional study carried out at Vinayaka Missions medical college and hospital. Conjunctival swabs were obtained from participants. All swabs collected from participants were subjected to standard microbiological techniques for the isolation of bacteria and fungi. A total of 120 swabs were collected from 120 participants (one swab from each eye). Overall 43 swabs were yielded growth and accounted for 35% of isolation rate. Gram positive cocci (83.72%) were isolated commonly. Gram negative bacilli was isolated only from 7 participants (16.28%). Staphylococcus aureus was found to be the predominant bacteria isolated and accounted for 27.91%. In this study, Staphylococcus aureus was found to be the most common ocular flora in healthy individuals. The higher culture positivity rate of Staphylococcus aureus probably reflects a more permissive environment. No fungi isolated in the present study.
