E coagulase-negative staphylococci were resistant to oxacillin. ABT 492 was also active against quinolone-resistant enterococci studied. The MIC 90 for quinolone-resistant E. faecalis was 0.5 g / ml, which is about 16 times st Stronger than trovafloxacin, 12 isolates go Gardens 3 and 6 VanA VanB clades. All compounds were weak activity GSK1363089 Foretinib xl880 of t against resistant St Strains of E. faecium, quinolone, with MIC90s of 32 g / ml for ABT 492 and trovafloxacin, including 14 isolates of VanA VanB St 4 and 5 Strains. Quinolone-susceptible Gram-negative pathogens. The power of ABT 492 was evaluated against quinolone-sensitive isolates of nine species of the family Enterobacteriaceae. The MIC90s of ABT 492 for E.
coli, Salmonella, Shigella, Klebsiella, Proteus mirabilis, Enterobacter, and Providencia were 0.25 g / ml or less and were comparable to MIC90s of trovafloxacin, levofloxacin and ciprofloxacin. Isolates of Citrobacter freundii and Serratia marcescens E7080 were somewhat less sensitive to ABT 492 as the comparators. Although ABT 492 MIC50s for these species were 0.25 and 0.5 g / ml MIC90s, 2 g / ml ABT 492 as active as ciprofloxacin against isolates of Pseudomonas aeruginosa ciprofloxacinsusceptible was MIC90s the two compounds were 0.25 g / ml . All four quinolones were less active against ciprofloxacin susceptible isolates of Stenotrophomonas maltophilia, MIC50s with 0.5 to 2 g / ml was ABT 492 st Amplifier challenging than trovafloxacin, levofloxacin and ciprofloxacin against gram-negative species. The MIC 90 of ABT 492 for H.
influenzae was 0.004 g / ml, this group of three and four lactamase producers lactamase negative St Strains resistant to ampicillin included. The MIC90s by ABT 492 were 0.002, 0.004 and 0.12 g / ml for M. catarrhalis, N. gonorrhoeae, Legionella pneumophila, respectively. Quinolone-resistant gram-negative pathogens. In general, showed ciprofloxacin-resistant Gram-negative St Mme a reduced sensitivity to ABT 492, trovafloxacin and levofloxacin against ciprofloxacin-sensitive St Strains of the same species. However MIC90s of ABT 492 for St resistant Strains ciprofloxacin in E. coli and Klebsiella pneumoniae were 16 and 8 g / ml, more than four times st doing Stronger than trovafloxacin, levofloxacin and ciprofloxacin. All four quinolones had little or no in vitro activity of t against resistant isolates resistant to the quinolone family of P.
aeruginosa and three ciprofloxacin isolates of Burkholderia cepacia. Two isolates of S. maltophilia were low rates of ciprofloxacin resistant, with MICs of ciprofloxacin of 4 g / ml, the MIC of ABT 492 of these isolates were 1 and 2 g / ml quinolone resistance in H. influenzae is very rare. ABT 492 retained the m Chtigste the four compounds, and the MIC of the strain is less sensitive to 0.12 g / ml, however, was the trovafloxacin MIC for this strain 1 g / ml and levofloxacin and ciprofloxacin were 16 L G Santander middle-income / ml, the six St strains of amino acids in GyrA at Ser84 and Asp88 with or without accompanying Ver changes in the park at Gly82, Ser84, or Glu88. Other pathogens. Susceptibility Th of additional keeping pathogenic species to ABT 492 were also evaluated. ABT 492 was two to four times a st Stronger than trovafloxacin, levofloxacin and ciprofloxacin against H. pylori. In addition, the power of ABT 492 against macrolide-resistant H. pylori s
