Title: Synergistic killing of vancomycin-resistant enterococci of classes A, B, and C by combinations of vancomycin, penicillin, and gentamicin. Author: Shlaes DM, Etter L, Gutmann L. Journal: Antimicrob Agents Chemother; 1991 Apr; 35(4):776-9. PubMed ID: 2069388. Abstract: Using both high and low inocula for time-kill curves, we examined the antibiotic killing of clinical isolates of glycopeptide-resistant enterococci (Enterococcus faecium, E. faecalis, and E. gallinarum) belonging to phenotypic resistance classes A, B, and C. None were resistant to high levels (greater than 500 mg/liter) of gentamicin. Vancomycin-penicillin-gentamicin resulted in 2 or more logs of killing above that of the most effective two-antibiotic combination for all strains except two of three E. gallinarum (VanC) strains and a constitutive mutant of a VanB strain. This strategy may be useful clinically.[Abstract] [Full Text] [Related] [New Search]
