Nine ciprofloxacin-resistant viridans group streptococci isolated from asymptomatic carriers were analyzed.

The nucleotide sequences of fragments of the parC, parE, gyrA, and gyrB genes showed considerable intra- and interspecies variations, and these variations mainly involved silent mutations. Three isolates had changes in Ser-79 of ParC (to Phe or Tyr). Phenotypic charact ...[more]
