Table 3. Streptococcus pneumoniae serotypes identified in 52 PCR-positive specimens from children with empyema, Australia, 2007–2009*.
| Serotype | No. (%) specimens |
|---|---|
| PCV7 serotypes | 2 |
| 14 | 1 (1.8) |
| 9V/9A |
1 (1.8) |
| Nonvaccine serotypes | 53 |
| 19A | 20 (36.4) |
| 3 | 18 (32.7) |
| 1 | 8 (14.5) |
| 7F/7A | 2 (3.6) |
| 22F/22A | 2 (3.6) |
| 6C | 1(1.8) |
| 15F | 1 (1.8) |
| 21 | 1 (1.8) |
*Two serotypes were identified in 3 specimens: 19A/3, 19A/1, and 6C/15F. The multiplex PCR reverse line blot assay cannot distinguish some pairs or groups of closely related serotypes, including 7F/7A, 22F/22A, and serogroup 6. Individual serotypes within serogroup 6 were distinguished by using serotype-specific PCR. PCV-7, 7-valent pneumococcal conjugate vaccine.
