Antimicrobial Susceptibility of 200 Blood Isolates of Coagulase-negative Staphylococci to 20 Antimicrobial Agents

Abstract

The in vitro susceptibility of 200 strains of coagulase-negative Staphylococci isolated from blood cultures to 20 antimicrobial agents including the newer beta-lactam compounds was compared. Rifampicin, vancomycin, nafcillin and gentamicin were the most active drugs. The newer cephalosporins and related beta-lactam antibiotics did not exhibit superior activity.
