Activity of nine fluoroquinolones against strains of Bordetella bronchiseptica

Thirty-two strains of Bordetella bronchiseptica were tested for their antim icrobial susceptibilities to nine fluoroquinolones. The most active agents were fleroxacin, temafloxacin, ciprofloxacin (MIC90 1 mu g/ml), ofloxacin, lomefloxacin and enoxacin (MIC90 2 mu g/ml).
