| Sample ID | Patient details and exposures 2 weeks before illness | Identification at 3 genes (similarity to GenBank isolates) |
||
|---|---|---|---|---|
| SSU rRNA | HSP70 | COWP | ||
| W971 | 25-year-old woman, swam regularly in a pool, holiday in UK forest park | W13 (790/790-bp homology to AY737559) | Skunk genotype (279/279-bp homology to AY120917) | Sequence data unavailable |
| W6863 | 30-year-old woman, immunocompetent, foreign travel, swam in a pool | Horse genotype (483/485 bp, 99.6%, similarity to AY273770) | Horse genotype (389/389-bp homology to AY273774) | C. parvum (503/506 bp, 99.4%, similarity to DQ388390) |
