[Microbiological study of the nasopharynx].
A microbiological study of the posterior wall of the nasopharynx have been carried out in 90 children subjected to adenoidectomy by chronically hypertrophied and infected adenoids. Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, Streptococcus pyogenes and Staphylococcus aureus are the most important pathogens responsible for upper respiratory tract infection. Adenoidectomy produces a physiological effect on the nasopharyngeal microflora by converting an abnormal flora into a nearly normal one. It has been found out that there is a relation between nasopharyngeal pathogens and the seasonal periods, showing a decrease in summer.
