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 aumentó a 31,3%
Palabras clave: Streptococcus pneumoniae; resistencia microbiana a las drogas; resistencia a penicilina; enfermedades respiratorias.
Respiratory pathogenic microorganism's sensitivity in community children
SUMMARY
OBJECTIVE: To determine the respiratory pathogens resistance to different antimicrobial drugs. MATERIAL AND METHODS: From April through November 2002, 177 patients attending the Mother-Child National Teaching Hospital Otorhinolaryngology outpatient's office were studied. RESULTS: Streptococcus pneumoniae was the most frequently isolated pathogenic bacteria (57,2%), followed by Moraxella catarrhalis (42,7%), Staphylococcus aureus (18,6%), Haemophilus influenzae (3,4%) and Streptococcus pyogenes (0,7%). Streptococcus pneumoniae showed resistance to the penicillin in 31,3%; 96,7 of Moraxella catarrhalis were producers of betalactamase and 7,4% of Staphylococcus aureus showed resistance to oxacillin. CONCLUSION: Streptococcus pneumoniae is the principal causal factor of respiratory infections in children and its resistance to the penicillin increased to 31,3%.
Key words: Streptococcus pneumoniae; drug resistance, microbial; penicillin resistance; respiratory tract diseases.
