Emergence of Vancomycin Resistance in Coagulase-Negative Staphylococci

Abstract

COAGULASE-negative staphylococci have been11 increasilgly recognized as causative agents in sevel l types of infection, including nosocomial bacteremia and infection of indwelling devices, such as prosthetic hea t valv1 , 2 2 a d neurosurgical and arteriovenous shunt3 , 4 4 Coagulase-negative staphylococci are also the most common agents responsible for peritonitis in patients undergoing continuous ambulatory peritoneal dialysi5 6 7 8 9 10 Until recentl, beta-lactamase-stable penicillins we e regarded as t e treatmen s f choi e f r staphylococcal infections.
