The clinical and bacteriological data of 61 cases of the acute otitis media were presented.The bacteriological correlation between the middle ear and the nasopharynx and oropharynx was studied; all of the cases were subjected to the studies on bacteria of the ear and of the nasopharynx and the oropharynx.The results are as follows:1) Sixty-four strains of bacteria were isolated from 61 middle ear effusions. Streptococcus pneumoniae was 64% of the strains, H. influenzae was 19%, beta-hemolytic streptococcus was 6 % and Staphylococcus aurous was 11%.2) There were 70 strains of potential pathogen isolated from the nasopharynx.Streptococcus pneumoniae was _??_9%, H. influenzae was 19%, beta hemolytic streptococcus was 6 % and staphylococcus aureus 16%.3) There were 67 strains of potential pathogen isolated from oropharynx. Streptococcus one_??_moniae was 50%, H. influenzae was 15%, beta-hemolytic streptococcus was 15%, staph.oerccus aureus was 19% and Klebsiella pneumoniae was 1.5%.4) The b_??_ correlations between the ear and the nasopharynx are as follows:Complete agreement, 72% of the cases; partial agreement, 20%; and disagreement, 8%.5) The bacteriologic correlations between the ear and the oropharynx are as follows:Complete agreement, 42% of the cases; partial agreement, 26%; and disagrrment, 25%.6) There is an extreme difference in the agreement rate between the nasopharynx and the oropharynx. Statistically, Chi-square test showed that the nasopharynx has a greater similarity to middle ear than the oropharynx in bacteria at the .05 level of significance.7) The coincident rate of bacteria between middle ear and nasopharynx are as follows:Streptococcus pneumoniae, 97% of cases; H. influeuzae and beta hemolytic streptococcus, 100%; and staphylococcus aureus, 20%.
