The effect of fleroxacin and ciprofloxacin on hemopoietic progenitor cells was tested in vitro. Cryopreserved bone marrow samples from 5 patients with acute myeloid leukemia who underwent bone marrow transplantation as well as samples from the respective donors were investigated in parallel. Regarding burst and/or colony formation by erythroid, neutrophil and macrophage precursors, no significant differences were detected with donor and transplanted bone marrows between control cultures and cultures containing 100 mg/l fleroxacin, while 100 mg/l ciprofloxacin inhibited cell proliferation completely. At 50 and 10 mg/l ciprofloxacin had a 50% and no inhibitory effect, respectively.
