Positive bacterial cultures were obtained in 104 children
(66.2%) with AOM, while no bacterial etiological agents were
identified in the remaining 33.8% of AOM children. A total of
131 different bacterial strains were isolated as two different
bacteria were isolated in 27 children with AOM. The most
frequently isolated pathogens were: S. pneumoniae (39.69%),
H. influenzae (16.03%), S. aureus (16.03%), S. haemolyticus (6.9%)
and S. pyogenes (5.34%); other bacteria were identified in 16.01% of
