Isolation and Identification of Multi-drug Resistant Bacteria from various sources and Antimicrobial Activity of Terminalia chebula Retz against isolated Multi-drug Resistant Bacteria

Abstract

Drug resistance is a threat to civilization, which results from over-prescription and irrational use of antibiotics. This has led to an increased demand for novel leads of herbal origin to overcome drug resistance. The present work involves the screening of various antibiotics against isolated Staphylococcus sp. from Hospital Effluent and the Minimum Inhibitory concentration for antibiotics namely Vancomycin, Erythromycin and Oxacillin were found to be 7.33+0.6 µg/ml 25.33+0.6 µg/ml and 27.33+0.6 µg/ml respectively whereas Minimum bactericidal concentration of Vancomycin, Erythromycin and oxacillin was found to be 180µg/ml; 146.67 + 0.3 µg/ml and 96.66 + 0.6 µg/ml respectively. Thus, the isolated bacteria were proved to be Multi-Drug Resistant. Haritaki (Terminalia chebula Retz) is given potential importance in Ayurveda for its properties to cure and prevent diseases. Terminalia chebula Retz is often known as “King of Medicines” and enlisted in Ayurveda for its extraordinary therapeutic contribution. The proved Multi-Drug Resistant bacteria was further subjected to a crude extract of Haritaki. Minimum Inhibitory Concentration for Terminalia chebula was found to be 1.33 +0.3 mg/ml and thus proved to be exhibiting potential anti-bacterial activity against isolated Multi-Drug Resistant Staphylococcus sp.
