RESUMO
Sparfloxacin is a new antimicrobial that, while maintaining a good activity against negative bacilli, has a better in vitro activity against gram positive bacteria such as S pneumoniae, intracellular pathogenesis and anaerobic bacteria. The aim of this work was to study the in vitro activity of sparfloxacin against bacteria isolated from patients with community acquired respiratory infections between october 1994 and january 1995. Using the E-test technique we studied the susceptibility to sparfloxacin, ciprofloxacin, ampicillin, amoxicillin/clavulinic acid, cefuroxime, cefotaxime, erythromycin, methicillin and nalidixic acid of 50 strains of pneumoniae, 50 strains of H influenzae, 50 strains of S. aureus and 50 strains of S pyogenes. Sparfloxacin was active against 100 percent of S. pneumoniae, H influenzae and S pyogenes strains. 22 percent of S aureus strains were resistant and the MIC 90 was 12 µg/ml. Sparfloxacin showed the best in vitro activity against H influenzae and S aureus, a similar activity with ampicillin but superior to all studied antimicrobial against and S pyogenes. It is concluded that aparfloxacin is a good antimicrobial for bacteria isolated from patients with respiratory infections
