[Bacteriologic study of 80 cases of acute otitis media in children].
BACKGROUND
Etiology of acute otitis media (AOM) in children is almost unknown in our country. We report 80 cases in order to study the most common pathogens.


METHODS
Eighty healthy children diagnosed of acute otitis media were studied between June 1989 and March 1992. Tympanocentesis was performed on each patient with an Abbocath-20G needle connected to a sterile syringe.


RESULTS
Some pathogens was isolated in 58 patients (72.5%) and in 22 (27.5%) the culture was sterile or with usual flora of the external canal. S. pneumoniae was recovered in 26 cases (32.5%); H. influenzae in 23 cases (28.7%); S. pyogenes 4 cases (5%); E. coli 4; P. aeruginosa 3 (3.7%); S. aureus 2 (2.5%); anaerobes 2 cases. M. catarrhalis was not found in any cases. In 6 children there was mixed flore.


CONCLUSIONS
In 80 children with AOM some pathogens was isolated in 58 cases (72.5%). The most common agents were S. pneumoniae and H. influenzae.
