TABLE 1.
Summary of shared pulsotypes clusters.
| Pulsotype cluster | MLST sequence type | Number of isolates in cluster | Number of patients in cluster | Median number of isolates/patient (range) | Approximate timespan of isolates* (years) |
| A | 1193 | 4 | 2 | 2 (2) | 5.2 |
| B | 73 | 14 | 3 | 3 (1–10) | 22.5 |
| C | 131 | 19 | 6 | 3 (2–4) | 10.5 |
* Approximate timespan of isolates refers to the approximate number of years over which isolates belonging to the indicated pulsotype/MLST sequence type were collected, across all patients.
