Development Of Fluorescing Methicillin Resistant Staphylococcus Aureus (Mrsa) As A Tool For The Screening Of Antibacterial Properties Of Mimusops Elengi Linn

Staphylococcus aureus is a Gram positive bacterium that can cause abscesses, various pyogenic infections (e.g. endocarditis and osteomyelitis), food poisoning and toxic-shock syndrome. It is also one of the most common causes of nosocomial infection (pneumoniae, septicaemia and surgical-wound inf...
