Microsphere, PCR, and IHC assay results of CTS cases.
| Clostridium cases (no. of cases) | Positive for C. sordellii | Positive for C. perfringens | ||||
|---|---|---|---|---|---|---|
| IHC* | PCR** | Microsphere assay | IHC* | PCR** | Microsphere assay | |
| C. sordellii (n = 10) | 10 | 10 | 10 | 10 | 0 | 0 |
| C. perfringens (n = 8) | 6 | 0 | 0 | 6 | 8 | 8 |
| C. sordellii and C. perfringens coinfection (n = 2) | 2 | 2 | 2 | 2 | 2 | 2 |
*IHC assay is specific for Clostridia but cannot speciate further.
**Conventional PCR assay targeting the phospholipase C gene of C. sordellii and C. perfringens.
