EFFICACY OF SOME PLANT EXTRACTS AGAINST SALMONELLA: AN IN VITRO STUDYS. SATISII, M. P. RAGIIAVENDRA, D.C. MOHANA AND K.A. RAVEESHA
Antibacterial agents isolated from plant origin could be exploited in human disease management caused by different species of Salmonella- AgLICOLIS extracts of leaves of forty plants selected based on traditional medicine and random selection from Mysore region, Karnataka (India) were subjected to in vitro antibacterial activity assay against Salmonella typin, Salm. typhonurium and Salm. paratyphi A employing cup diffusion method. It is indicated that six plants exhibited antibacterial activity against test pathogens and the spectrum of activity was varied among the pathogens. Antibacterial activity of the different solvent extracts of six plants, which recorded antibacterial activity in aqueous extract, was compared with six antibiotics. The inhibitory activity was highly significant in the methanol extract of Anacardium occiden tale, Acacia nilotica and Lawsonia inermis. Present investigation has led identi the potential candidate plants for further work on isolation and characterization of the active principle responsible for antibacterial activity and its exploitation as therapeutic agent against disease caused by species of Salmonella.
