In vivo efficacy of T-3811ME and other antibacterial agents against experimental pneumonia caused by M. pneumoniae FH in hamsters. For results at 2 days an asterisk indicates a P of <0.05 for T-3811ME versus control, trovafloxacin, levofloxacin, and clarithromycin (except clarithromycin at 40 mg/kg), or for clarithromycin (40 mg/kg) versus control. For results at 5 days, an asterisk indicates a P of <0.05 for T-3811ME versus control, trovafloxacin, levofloxacin, and clarithromycin. Results are presented as Means + standard deviations (error bars) (untreated group, n = 11; treated groups, n = 5 to 6), for 2 or 5 days of therapy.
