title: In vitro and intracellular activities of LBM415 (NVP PDF-713) against Legionella pneumophila.
abstract: LBM415 activity against extracellular and intracellular Legionella pneumophila was studied. The LBM415 MIC50 for 20 Legionella sp. strains was 4 microg/ml, versus 0.06, 0.25, and <or=0.03 microg/ml for azithromycin, erythromycin, and levofloxacin, respectively. LBM415 (0.5 and 16 microg/ml) reversibly prevented intracellular growth of two L. pneumophila strains and was less active than erythromycin.
