Figure 3. Phylogenetic Tree of the S. koreensis Isolates from the NIH Clinical Center.

Figure 3.

The phylogenetic tree was constructed on the basis of single-nucleotide variants (SNVs) across the core genome. Circles of the same color at the end of the nodes indicate environmental isolates (Env) from the same sink. Black circles indicate that no other isolates were cultured from a given sink. The circles at the end of the nodes for isolates obtained from patients are colored to match the isolates from the sink in the room in which the patient was staying. The labels of isolates obtained from patients are highlighted in red, and isolates obtained from sinks are labeled in black.
