Comparative in vitro study of the activity of moxifloxacin and other antibiotics against 150 strains of penicillin non-susceptible Streptococcus pneumoniae and against 110 strains of ampicillin-resistant Haemophilus influenzae isolated in 19992000 in Spain
Servicio de Microbiología, Hospital de Móstoles, 28935 Móstoles, Madrid, Spain
Sir,
Antimicrobial resistance amongst strains of Haemophilus influenzae and Streptococcus pneumoniae has limited the usefulness of first-line agents in some clinical settings. There is thus a clear need for new antibiotics, in particular those active against resistant strains. Moxifloxacin is an 8-methoxyquinolone with high activity against Grampositive bacteria, including penicillin-intermediate and -resistant pneumococci.1,2 As with earlier fluoroquinolones, moxifloxacin shows excellent activity against H. influenzae.1,2 Moxifloxacin has a bactericidal effect against both pathogens, and its post-antibiotic effect was similar to that of other fluoroquinolones and increased with increasing concentrations.3
The aim of this study was to assess the antimicrobial susceptibility to moxifloxacin and 14 other
