TABLE 2.
Diversity and major PFGE clusters of the three serotype 19A populations analyzed
| Population | % SID (95% CI) | % of isolates in the following PFGE clustera: |
|||||||
|---|---|---|---|---|---|---|---|---|---|
| 4 | 8 | 9 | 10 | 13 | 14 | 15 | 17 | ||
| Carriage isolates (n = 110) | 78.8 (74.5-83.0) | 6 | 1 | 1 | 2 | 2 | 21 | 34 | 24 |
| Invasive isolates (n = 121) | 82.2 (76.8-87.5) | 12 | 5 | 5 | 1 | 12 | 7 | 7 | 37 |
| Noninvasive isolates (n = 57) | 81.4 (73.3-89.6) | 4 | 7 | 2 | 9 | 4 | 16 | 9 | 39 |

PFGE clusters that included at least 5% of any of the three populations analyzed are represented. When the proportion of the population grouped into one of the PFGE clusterswas ≥10%, the value is highlighted in boldface.
