Despite their mechanistic importance, the DNA breakage determinants are not understood for any bacterial type II enzyme. We investigated DNA cleavage by Strepto...
Six quinolones were tested on 817 consecutive pneumococcal isolates for which ciprofloxacin MICs were high (> or =2 microg/ml); the isolates had been collected during two recent Spanish surveillance studies. For strains for which the ciprofloxacin MIC was >or =4 microg/ml, the MICs at which 90% of the isolates tested against gemifloxacin, moxifloxacin, gatifloxacin, sparfloxacin, levofloxacin, ...
