Biological Activity
|
Quinolone |
Danofloxacin (20 h) exhibits significant in vitro inhibitory activity against Escherichia coli isolates from Gushi chickens, with an MIC50 of 0.5 μg/mL; the MIC50 against the quality control strain E. coli ATCC 25922 is 0.125 μg/mL[1].
Danofloxacin (0.008-128 μg/mL; 20 h) exhibits certain inhibitory activity against swine-derived Escherichia coli isolates, with an MIC50 of 4 μg/mL and an MIC90 of 128 μg/mL. The epidemiological cut-off value covering the wild-type population is 8 μg/mL[3].
Danofloxacin (1/4 MIC-32× MIC; 0-24 h) exhibits concentration-dependent bactericidal activity against the Escherichia coli strain JLP95, with significant efficacy observed at concentrations of 4× MIC and above[3].
