Table 2.
Pneumococcal co-colonization as measured by traditional culture and quantitative molecular PCR (n = 374).
| Culture | qPCR | p-valuea | |
|---|---|---|---|
| Not colonized | 108(29) | 67(18) | <0.001 |
| Colonized | 266(71) | 307(82) | |
| 1 serotype | 239(99.8) | 176(57.3) | <0.001 |
| 2 serotypes | 12(4.5) | 59(19.2) | <0.001 |
| 3+ serotypes | 0 | 29(9.4) | <0.001 |
Values are number (%). For multiple carriage percentage values are calculated based on total number of samples positive for LytA. PCV7, 7-valent pneumococcal conjugate vaccine. aAs defined by McNemer’s test. p-values of < 0.05 were considered significant.
