Table 2.
Distribution of otopathogens from children with AOM where same otopathogens were observed in the NP and MEF site (N = 165)
| Correlation of MEF otopathogens with their NP site | |||
|---|---|---|---|
| Otopathogens | Number | Percentage calculated with exact match of otopathogens with MEF total (n = 165) | Percentage calculated with total AOM cases (n = 530) |
| S. pneumoniae | 37 | 22.4 | 6.98 |
| Nontypeable H. influenzae | 61 | 37.0 | 11.5 |
| M. catarrhalis | 29 | 17.6 | 5.5 |
| NTHi + S. pneumoniae | 9 | 5.5 | 1.7 |
| M. catarrhalis + S. pneumoniae | 19 | 11.5 | 3.6 |
| NTHi + M. catarrhalis | 4 | 2.4 | 0.8 |
| NTHi + M. catarrhalis + S. pneumoniae | 1 | 0.6 | 0.2 |
| Other bacteria | 5 | 3.0 | 0.9 |
Note: In 354 (68.2%) AOM cases the MEF etiology didn’t match exactly with the NP site of the children.
