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.
Insights
The most common causes of acute otitis media (AOM) in children were identified as Streptococcus pneumoniae and Haemophilus influenzae. This study analyzed 80 pediatric cases to understand common pathogens.
Area of Science:
- Pediatric infectious diseases
- Microbiology of otitis media
Background:
- The etiology of acute otitis media (AOM) in children remains largely unknown in our region.
- This study investigated the common causative pathogens in pediatric AOM cases.
Purpose of the Study:
- To identify the most frequent bacterial pathogens responsible for acute otitis media in children.
- To establish an etiological profile for AOM in the studied pediatric population.
Main Methods:
- Eighty healthy children diagnosed with AOM between June 1989 and March 1992 were enrolled.
- Tympanocentesis was performed using an Abbocath-20G needle and sterile syringe for sample collection.
Main Results:
- Pathogens were isolated in 58 patients (72.5%); 22 (27.5%) had sterile cultures or normal external canal flora.
- Streptococcus pneumoniae was identified in 32.5% of cases, and Haemophilus influenzae in 28.7%.
- Other identified pathogens included S. pyogenes, E. coli, P. aeruginosa, S. aureus, and anaerobes; M. catarrhalis was not detected.
Conclusions:
- Pathogens were isolated in a significant majority (72.5%) of the 80 children with AOM.
- The primary etiological agents identified were Streptococcus pneumoniae and Haemophilus influenzae.
