Single-dose trovafloxacin (15 mg/kg given intravenously [i.v.]) and ampicillin (40 mg/kg given i.v.) protected 38 and 33% of animals challenged with an ampicillin-tolerant strain of Streptococcus oralis, respectively. As a double-dose regimen, trovafloxacin afforded total protection (100%; P < 0.001 versus controls). Trovafloxacin is the first fluoroquinolone effective in preventing experimental streptococcal endocarditis.
