Comparison of NP Colonization at Healthy and AOM Visits along with MEF isolates during AOM
| Isolates | Healthy NP colonization | AOM NP colonization | AOM MEF |
|---|---|---|---|
| Number (%) | Number (%) | Number (%) | |
| S. pneumoniae | 292 (14.1) | 70 (13.2) | 110 (20.8) |
| Nontypeable H. influenzae | 97 (4.7) | 97 (18.2) | 166 (31.3) |
| M. catarrhalis | 382 (18.4) | 78 (14.7) | 71 (13.4) |
| NTHi + S. pneumoniae | 60 (2.9) | 52 (9.8) | 19 (3.6) |
| M. catarrhalis + S. pneumoniae | 245 (11.8) | 99 (18.6) | 22 (4.2) |
| NTHi + M. catarrhalis | 37 (1.8) | 39 (7.3) | 10 (1.9) |
| NTHi + M. catarrhalis + S. pneumoniae | 59 (2.8) | 35 (6.6) | 1 (0.2) |
| Other bacteriaǂ | 870 (41.9) | 35 (6.6) | 44 (8.3) |
| No Bacteria | 36 (1.7) | 27 (5.1) | 87 (16.4) |
ǂOther bacteria were only sought when canonical otopathogens (S. pneumoniae, NTHi and M. catarrhalis) were not detected in the visits. They may have been present along with main otopathogens but were not included in the calculations.
