Ca. Day et al., INCREASED SUSCEPTIBILITY OF PSEUDOMONAS-AERUGINOSA TO CIPROFLOXACIN IN THE PRESENCE OF VANCOMYCIN, Antimicrobial agents and chemotherapy, 37(11), 1993, pp. 2506-2508
Vancomycin in combination with ciprofloxacin exhibited synergy against
7 of 10 strains of Pseudomonas aeruginosa. MICs for the microbial str
ains used in this study ranged from 0.0325 to 3.0 mug/ml for ciproflox
acin and from 23.5 to >188 mug/ml for vancomycin. Combinations of thes
e antibiotics, tested in a checkerboard pattern, gave fractional inhib
itory concentrations of 0.5 or less for 7 of the 10 strains tested.
