Abstract excerpt
The aim of this study was to characterize quinolone resistance mechanisms in strains of Streptococcus pneumoniae with increased MICs of ofloxacin. These strains were also tested for their susceptibility to a battery of quinolone antimicrobial agents, including gemifloxacin. Of the S. pneumoniae isolates used, 27 were susceptible to ofloxacin, 18 intermediate and 48 resistant (ofloxacin MIC <4, 4 and >4 mg/L,...
