We report the activity of delafloxacin, a new fluoroquinolone with high affinity for both topoisomerase IV and DNA gyrase, against highly-levofloxacin-resistant invasive strains of Streptococcus pneumoniae. A total of 173 highly-levofloxacin-resistant (MIC32mg/L) S. pneumoniae invasive isolates were studied. The strains were isolated from blood (n=162) and other sterile fluids (n=11). Serotyping was performed by the Pneumotest-Latex and Quellung reaction. Delafloxacin, levofloxacin, penicillin, cefotaxime, erythromycin and vancomycin MICs were
