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%.
