Bactericidal Efficacy of Allium sativum (garlic) Against Multidrug Resistant Vibrio cholerae O1 Epidemic Strains
Abstract
In recent years, emerging trend of antibiotic resistance in Vibrio cholerae associated with cholera epidemics is a matter of serious concern for the management of the disease. Indiscriminate use of antibiotics generally results in selection of antibiotic resistant strains. Introduction of newer antibiotics is a challenging task for the researchers as bacteria soon attain resistance. Therefore, identifying natural compounds of medicinal importance for control of cholera would be the best alternative. Garlic (Allium sativum) was recognised for many centuries in early Chinese, Egyptian and Indian civilisations as an herbal or traditional medicine. In present study, garlic was selected for screening of antimicrobial efficacy against V. cholerae. A total of 55 V. cholerae strains isolated from various outbreaks/epidemics were subjected to antimicrobial testing as per CLSI, USA 2010 guidelines. Antimicrobial screening of garlic extract was performed against all the multidrug resistant strains of V. cholerae. The garlic extracts showed antibacterial activity against all the V. cholerae strains tested, irrespective of their origin, multidrug resistance and virulence. Antibacterial efficacy of garlic on V. cholerae was also evident from in vivo study on sealed adult mice model. Thus, the Garlic extract harnesses the potential to control infection of multidrug resistant V. cholerae, especially in outbreak like situations in remote and under developed areas where drug supply itself is a challenge
