This study analyzes the in vitro activities of levofloxacin and other commonly used antimicrobials against middle ear fluid, nasopharyngeal, and oropharyngeal pathogens obtained from children with otitis media at risk of having a resistant pathogen. Levofloxacin proved to be very active against these pathogens and had intermediate activity against Streptococcus pyogenes.
