Medium-dependent zone size discrepancies associated with susceptibility testing of group D streptococci against various cephalosporins.

Abstract

Mueller-Hinton (MH) agar media from various commercial sources, either supplemented or not supplemented with 5% sheep blood, were studied to determine their effect on disk diffusion susceptibility testing results obtained with 90 strains of group D streptococci and four cephalosporins. The cephalosporins investigated included cephalothin, cefamandole… (More)
