Abstract
The susceptibilities of mycoplasmas to a new quinolone, trovafloxacin (CP-99,219), were compared with those to sparfloxacin and ofloxacin. Mycoplasma pneumoniae was as susceptible to trovafloxacin (MIC = 0.25 microgram/ml) as to sparfloxacin and fourfold less susceptible to ofloxacin. Mycoplasma hominis was highly susceptible to trovafloxacin (MIC = 0.06 microgram/ml) and sparfloxacin (MIC = 0.03 microgram/ml) and less susceptible to ofloxacin (MIC = 0.5 microgram/ml). Ureaplasma urealyticum was most susceptible to trovafloxacin, with susceptibilities ranging from 0.06 to 0.5 microgram/ml compared with 0.25 to 1.0 microgram of sparfloxacin per ml and 1 to 4 micrograms of ofloxacin per ml.
