M. Venditti et al., ANTIMICROBIAL SUSCEPTIBILITIES OF ENTEROCOCCI ISOLATED FROM HOSPITALIZED-PATIENTS, Antimicrobial agents and chemotherapy, 37(5), 1993, pp. 1190-1192
One hundred and one isolates of Enterococcus species isolated recently
from hospitalized patients were evaluated in vitro for antibiotic sus
ceptibility. Teicoplanin and mideplanin were the most active agents, f
ollowed by ramoplanin, vancomycin, ciprofloxacin, ampicillin, and imip
enem. High-level resistance to gentamicin (MIC > 500 mug/ml) and/or st
reptomycin (MIC > 2,000 mug/ml) was found in 60 isolates. High-level r
esistance to ampicillin (MIC greater-than-or-equal-to 16 mug/ml) was f
ound in 17 isolates. MBC studies revealed that ramoplanin possesses si
gnificant bactericidal activity.
