Antimycobacterial Potential Of Secondary Metabolites Of Actinobacteria From A Tropical Mangrove In Northern Peninsular Malaysia

Actinobacteria play a crucial role in discovery of new antibiotics for diseases with known antimicrobial resistance, such as multidrug-resistant tuberculosis (TB) caused by Mycobacterium tuberculosis (MTB), which is becoming a major impediment to TB control worldwide. In this study, novel actinobact...
