Co-carriage of Staphylococcus aureus , Streptococcus pneumoniae , Haemophilus influenzae and Moraxella catarrhalis among three different age categories of children in Hungary

摘要

Background The nasopharynx can from time to time accommodate otherwise pathogenic bacteria. This phenomenon is called asymptomatic carriage. However, in case of decreased immunity, viral infection or any other enhancing factors, severe disease can develop. Our aim in this study was to survey the nasal carriage rates of four important respiratory pathogens in three different age groups of children attending nurseries, day-care centres and primary schools. This is the first study from Hungary about the asymptomatic carriage of H . influenzae and M . catarrhalis .
