OBJETIVO: Determinar la resistencia de los patógenos respiratorios a diferentes antimicrobianos. MATERIAL Y MÉTODOS: Entre abril y noviembre de 2002 se estudió 177 pacientes que asistieron al consultorio externo de otorrinolaringología del Hospital Nacional Docente Madre-Niño San Bartolomé. RESULTADOS: Streptococcus pneumoniae fue la bacteria patógena más aislada (57,2%), luego Moraxella catarrhalis (42,7%), Staphylococcus aureus (18,6%) y en pequeña cantidad Haemophilus influenzae (3,4%) y Streptococcus pyogenes (0,7%). Streptococcus pneumoniae presentó 31,3% de resistencia a la penicilina. El 96,7% de Moraxella catarrhalis fueron productoras de betalactamasa y 7,4% de los Staphylococcus aureus fueron resistentes a la oxacilina. CONCLUSIÓN: Streptococcus pneumoniae es el principal agente causal de los procesos infecciosos altos en niños y su resistencia a la penicilina aumen...

Otorhinolaryngologic diseases in two Hospitals of Lima, hoth in children and ill adults, were studied looking for Moraxella catarrhalis along 12 months. 318 samples front the same miniher of patients were obtained; 40% of which were negative for pathogenic bacteria. Of the remaining 60%, 31% showed Staphilococcus aurcus as the causative agent, followed by Streptococcuspneumoniae in the 19%,Miraxella catarrhalis lit 16% and Haemophilus influenzae in 10%.The most important symptom was purulent rhinorrhea.Streptococcus pneumoniae, Moraxela catarrhalis and Haemophilus influetizae were isolated, ill most of cases, front boys younger than 14 years old.15% of the S. aureus isolated strains were oxacillin-resistant, 11% of tile S. neumoniae isolated strains were penicillin- resistant, and 70% of the M. catarrhalis as well as 5% of the H. influenzae isolated strains were, lactamase producers.Our ...
