Journal Title: Journal of Medical Science And clinical Research - Year 2017, Vol 5, Issue 5
Abstract
Background: Corneal ulcers are of everyday occurrence and the communities working in farms, quarries and mining areas, are the major sufferers of corneal blindness in our country. Objective - A study on aerobic bacterial etiological agents in suppurative keratitis. Materials and Methods: The specimen was collected from suppurative keratitis cases irrespective of prior antibiotic treatment during the period of one year from March 2012 to February 2013. Those cases with loss of corneal epithelium with signs of inflammation, and stromal infiltration were taken as suppurative keratitis cases. Five or more corneal scrapings taken were used for Gram staining, inoculation on to Sheep Blood Agar (SBA), Chocolate Agar, Mac Conkey Agar. Extreme care is taken to keep the entire process sterile. Results: During the one year period, out of the 100 patients with suppurative keratitis; there were 12 (17.64%) bacterial isolates. Staphylococcus aureus was the most common gram positive isolate and Psedomonas aeruginosa was the common gram negative one. Conclusions: Although corneal ulceration is a very rare cause of mortality, it is one of the important causes of morbidity and disability in South Kerala, especially among lower socio-economic groups. The present study gives an insight about the bacterial aetiological agent of suppurative keratitis. The results of this study are similar to that in other parts of India. These findings have important public health implications for the treatment and prevention of corneal ulceration in the developing world.
