DS-8587 is a novel broad-spectrum fluoroquinolone with extended antimicrobial activity against both Gram-positive and Gram-negative pathogens. In this study, we evaluated the in vitro and in vivo antibacterial activity of DS-8587 against multidrug-resistant (MDR) Acinetobacter baumannii. The MIC range of DS-8587 against MDR A. baumannii was 0.25-2 mg/L.(More)
The in vitro and in vivo antibacterial activities of levofloxacin (LVFX), a quinolone antibacterial, against clinically isolated Legionella pneumophila were investigated in comparison with those of existing antimicrobial agents approved for legionnaires disease. The minimum inhibitory concentrations (MICs) of the agents against 42 strains of L. pneumophila(More)
We present here a new model of Legionella pneumophila lung infection in DBA/2 mice. By intranasal inoculation with 106 colony-forming units of L. pneumophila strain suzuki serogoup 1, persistent non-lethal lung infection was established as reflected by the detection of more than 10(4) CFU/lung of the organism 14 days after infection. Treatment of mice with(More)
