Comparison of antimicrobial susceptibility patterns among coagulase-negative staphylococci

Coagulase-negative staphylococci, identified as S. epidermidis, S. saprophyticus, S. haemolyticus, S. hominis, and S. warneri, were tested for susceptibility to a number of antimicrobial agents by disk agar diffusion and broth microdilution methods, S. warneri and S. saprophyticus were found to be the most susceptible, and S. haemolyticus and S. epidermidis were found to be the least susceptible. Differences in antimicrobial susceptibility patterns are discussed, along with their epidemiological and therapeutic implications.
