Aerobic Bacteriological Profile in Cases of Ocular Infections in a Tertiary Care Hospital (Navodaya Medical College & Research Centre, Raichur)

Abstract

Background: Ocular infections are one of the common diseases of the eye. The current trends in the etiology of ocular infections and their antibacterial susceptibility pattern must be updated to help the clinicians. Objective: To identify the aerobic bacterial profile of ocular infections in patients attending Ophthalmology OPD/IPD. Materials and Methods: 102 patients attending Ophthalmology OPD/IPD in Navodaya Medical College Hospital & Research Centre were analysed from Nov 2010 to Sep 2011. Using predefined inclusion and exclusion criteria, samples were collected according to the standard protocol. These were cultured for microorganisms ( aerobic bacterial ) were identified. Drug susceptibility was done using Kirby Bauer disc diffusion method. Results: The most common bacterial pathogen isolated were Staphylococcus aureus(32.8%) followed by Staphylococcus epidermidis (25%),other organisms isolated are Streptococcus pneumonia (14.1%), Kiebsiella pneumonia (6.3%), Escherichia coil (4.7%). Bacterial isolates were highly susceptible to Vancomycin(100%), Gentamicin(94.3%) among Gram positive organisms and among Gram negative organisms it is highly susceptible to Tobramycin(100%) and Imipenem(90.9%). Conclusion: The study suggest that Staphylococcus aureus and Staphylococcus epidermidis are the most common etiological agents of Ocular infections. Most of the strains were sensitive to Vancomycin and Tobramycin.
