Antibiotic susceptibility testing (agar disk diffusion and agar dilution) of clinical isolates of Enterococcus faecalis and E. faecium: comparison of Mueller-Hinton, Iso-Sensitest, and Wilkins-Chalgren agar media.


Forty-two isolates of Enterococcus faecalis and 56 isolates of Enterococcus faecium, including 8 vancomycin-resistant strains, were examined for comparative susceptibility to 27 antimicrobial drugs with the agar dilution method, employing Mueller-Hinton (MHA), Iso-Sensitest (ISTA), and Wilkins-Chalgren (WCA) agar. The Bauer-Kirby agar disk diffusion method… (More)
