A bacteriological study on otorrhea in 152 cases of acute purulent otitis media in children was carried out. Forty strains of Haemophilus influenzae (26%), 35 strains of Streptococcus pneumoniae (23%), 33 strains of Staphylococcus epidermidis (22%), 32 strains of Staphylococcus aureus (21%), 3 strains of Streptococcus pyogenes (Group A) (2%) and other 8 strains (5%) were isolated.Reviewing the annual data of otorrhea isolates from 1963 to 1980, Staphylococcus aureus and Streptococcus pyogenes (Group A) of gram-positive cocci decreased, while Haemophilus influenzae of gram-negative bacIlli remarkably increased. Increase of Haemophilus influenzae is caused by the technical improvement of isolating the said bacterium and also actual increase of otitis media by the pathagen of Haemophilus influenzae.One-forth of the children with otorrhea showed the hard-curable process such as recurrenceor recovery-delaying. Haemophilus influenzae was isolated in a high rate (46.9%) from otor-rhea of the children with hard-curable otitis media.
