TABLE 4.
Cluster interpretation.
| Number of pipelines | Number of laboratories | |||||
| Cluster 1 | Cluster 2 | Cluster 3 | Cluster 1 | Cluster 2 | Cluster 3 | |
| No direct transmissions | 8 | 6 | 0 | 5 | 4 | 0 |
| Suspicion of direct transmission | 1 | 2 | 2 | 1 | 1 | 2 |
| Likely lab contamination | 0 | 0 | 7 | 0 | 0 | 4 |
Note that pipeline R, based on MinION data, did not fully identify cluster 2, since strain 4 was missing from its tree. Hence, we only evaluated eight pipelines and five laboratories for cluster 2.
