Antimicrobial Activity of Partially Purified Extract of Streptomyces Sp. on MRSA
Abstract: Methicillin-resistant Staphylococcus aureus (MRSA) is a major cause of increasingly prevalent, difficult and expensive-to-treat nosocomial as well as community-acquired infections worldwide. Accurate and rapid detection of MRSA in a clinical laboratory is of utmost importance to avoid treatment failure as these strains are multidrug resistant and there are limited options to treat these infections. Hence, exploring newer antibacterial substances is the need of the hour. In this study, phenotypically and …
