E. Fasola et al., COMPARATIVE ACTIVITIES OF LY-333328, A NEW GLYCOPEPTIDE, AGAINST PENICILLIN-SUSCEPTIBLE AND PENICILLIN-RESISTANT PNEUMOCOCCI, Antimicrobial agents and chemotherapy, 40(11), 1996, pp. 2661-2663
Microdilution MIC testing was used to test the susceptibility of 202 p
neumococci to LY 333328 and six other agents. LY 333328 was the most a
ctive glycopeptide (MIG at which 90% of the pneumococci were inhibited
[MIC(90)], 0.008 mu g/ml), followed by teicoplanin (MIC(90), 0.06 mu
g/ml) and vancomycin (MIC(90), 0.5 mu g/ml). Rifampin resistance was s
een in some penicillin-resistant strains. The MICs of imipenem and cef
triaxone rose with those of penicillin. Time-kill testing confirmed th
e excellent antipneumococcal activity of LY 333328.
