title: [The microbiology of secretory otitis].
abstract: The AA. realize a comparative study on the differences between the nasopharyngeal microbial flora of 50 children suffering a secretory otitis and other 40 children without middle ear disease. In nasopharyngeal cultures the pathogenic flora (Haemophilus influenzae, Streptococcus pneumoniae, Moraxella catarrhalis, Streptococcus beta hemoliticus group A, Staphilococcus aureus) amounted for 96 percent in children with secretory otitis, which figure was reduced to 80 percent in healthy infants (p < 0.05). Haemophilus influenzae was the most identified microorganism in a both nasopharyngeal and otic flora. We have found a significative association (p < 0.001) among nasopharyngeal and otic flora of each individual.
