Increased ROS Generation: Implication in Antibacterial Activity of Evolvulus nummularius against Multidrug Resistant Gram Negative Bacterial Strains
Journal Title: International Journal of Current Microbiology and Applied Sciences (IJCMAS) - Year 2017, Vol 6, Issue 1
Abstract
Evolvulus nummularius, is ethnomedicinally used as a medicine for hysteria, to cure burns, cuts, wounds and scropion stings. This plant has antihelminthic activity, wound healing activity, poor sedative and anticonvulsant properties. In this study, the antibacterial activity of crude methanol extract of E. nummularius was studied against three gram negative multidrug resistant strains E. aerogenes, P. aeruginosa and K. pneumoniae. This plant extract showed both bacteriostatic and bactericidal activity against all these bacterial strains. The extract was most active against E. aerogenes. In growth analysis study, it was obtained that, after treatment with IC50 dose for each bacterial strains, the lag phase become extended compared to untreated bacterial cells. To understand the mechanism of action of Evolvulus nummularius the reactive oxygen species (ROS) was estimated and result showed that, reactive oxygen species were increased (~ 35-60%) in presence of IC50 dose of Evolvulus nummularius.
