Comparative in vitro activities of the investigational fluoroquinolone DC-159a and other antimicrobial agents against human mycoplasmas and ureaplasmas.

Academic Article


  • The in vitro susceptibilities of 151 unique clinical isolates of Mycoplasma pneumoniae, Mycoplasma hominis, Mycoplasma fermentans, Mycoplasma genitalium, and Ureaplasma species to DC-159a, an investigational fluoroquinolone, in comparison with those to other agents were determined. Macrolides were the most active agents against M. pneumoniae and M. genitalium, whereas clindamycin was most active against M. hominis. DC-159a MICs were or=99.9% of the inoculum at 24 h for 2 isolates. The excellent in vitro activity of DC-159a demonstrates its potential for use in the treatment of infections due to mycoplasmas and ureaplasmas.
