Estudio de la actividad comparativa in vitro de telitromicina en patógenos respiratorios adquiridos en la comunidad en 13 centros clínicos chilenos

Two hundred eighty strains isolated from patients with respiratory infections, werestudied. The strains studied were S pneumoniae, penicillin sensitive (SPNS:57); intermediate(SPNI:35), resistant (SPNR:25); S pyogenes (SP:57); H influenzae (HIN 51); M catarrhalis(MC:25) and S aureus meticillin sensitive (SAUS:30). Minimal inhibitory concentration (MIC)by broth microdilution was studied for telitrhomycin and levofloxacin in all strains. Otherantimicrobials studied, but not in all strains were erythromycin, clindamycin, trimetoprimsulphamethoxazole, oxacillin, amoxicillin-clavulanic acid and cefuroxime.
