The in-vitro activity of tosufloxacin (A-61827) was compared with that of temafloxacin, ciprofloxacin and selected members of other groups of antimicrobial agents, against 684 recent distinct clinical isolates and strains with known mechanisms of resistance. Against members of the Enterobacteriaceae
