Table 2.
Serogroups (with the highest titer by a microscopic agglutination test (MAT)) of confirmed leptospirosis from 12 hospital-based sites in Thailand, 2017.
| Infecting Serogroups | Severe Leptospirosis n (%) N = 29 * |
Non-Severe Leptospirosis n (%) N = 9 ** |
Total n (%) N = 38 |
|---|---|---|---|
| Australis | 14 (48.4) | 8 (88.9) | 22 (57.8) |
| Icterohaemorrhagiae | 3 (10.3) | 0 | 3 (7.9) |
| Pyrogenes | 2 (6.9) | 1 (11.1) | 3 (7.9) |
| Sejroe | 2 (6.9) | 0 | 2 (5.3) |
| Autumnalis | 2 (6.9) | 0 | 2 (5.3) |
| Djasiman | 2 (6.9) | 0 | 2 (5.3) |
| Hebdomadis | 2 (6.9) | 0 | 2 (5.3) |
| Bataviae | 1 (3.4) | 0 | 1 (2.6) |
| Grippotyphosa | 1 (3.4) | 0 | 1 (2.6) |
* Four cases had no information on the serogroup due to testing positive formore than one pathogenic serogroup with the same high titer; ** Two cases had negative results by the MAT.
