Antimicrobial activity of plant based Essential Oils and Synergistic effect against selected Human Pathogenic Bacteria

Abstract

The occurrence of multidrug resistant by pathogens is a universal issue for providing tolerable treatment for various infectious diseases. The predictable anti-microbial proxies are relatively active against plentiful strains, still need of more drugs against multidrug resistant pathogens. Herbal drugs have potential against antimicrobial activity from ancient days and their treatment of pathogenic diseases is increasing for developing plant based natural products. Essential oils have combat against antibiotic resistant bacteria. Thus our study was focused on plant based essential oil against human pathogenic bacteria. The necessary oil extracted from Curcuma longa and C. martini revealed protuberant anti-microbial accomplishments against B. subtilis, Escherichia coli, P.  aeruginosa and S. aureus.      Low concentration of C. longa oil at 10 µl inhibited the growth of all strains Bacillus subtilis followed by E. coli and S. aureus. Maximum bustle was noted in P. aerogenosa at 40 µl in both C. longa and C. martini oils. Human pathogenic strain treated with C. martini oil showed maximum inhibition in P. aerogenosa followed by B. subtilis, E. coli and S. aureus. Synergistic activity of oils against the strains showed maximum inhibition at 40 µl in P. aerogenosa.
