ABSTRACT

ABSTRACT: The aim of the study is to evaluate the combined anti bacterial activity of Daucus Carota, Jasminum auriculatum and Pithecellobium dulce against lap top keyboard surface bacteria. The keyboard is a very dynamic environment,Since the keyboard is con-stantly in contact with human hands, there will constantly be a stream of things leaving the hands and entering the keyboard. The plants chosen for the study are having good pharmacological activities. In the present study, the bacteria were isolated by swabbing on the key board of Laptop in the Microbiology lab. Three plants were selected to evaluate their anti bacterial activity against lap top keyboard surface bacteria. Disinfectants were used to clean key board. A total seven organisms were isolated and grown on nutrient agar media. The plant leaves were shade dried and mechanically grinded and allowed for methanol extraction. Anti bacterial activity was assessed by Agar well diffusion method against all the isolates. Among all the isolates plant extract forms inhibition zone on IS 2 (7 mm, 6mm, 4 mm for 50 mg/ ml, 100 mg/ml, 200 mg/ ml), IS 4 (7mm, 6mm, 4mm for 50 mg/ ml, 100 mg/ml, 200 mg/ ml).By this study, it is concluded that plant extract is the replacement of Chemical disinfectants.
