| Strain | Nucleotide divergence (%) from |
|||
|---|---|---|---|---|
| NY99 | Cluster A | Cluster B | Cluster C | |
| AZ10–581 | 0.58 | 0.25–0.52 | 0.66–0.85 | 0.61–1.10 |
| AZ10–91 | 0.66 | 0.74–1.04 | 0.49–0.52 | 0.69–1.16 |
| AZ10–892 | 0.65 | 0.84–1.18 | 0.92–1.04 | 0.27–0.62 |
*Strains used for analysis in each cluster are those color coded with representative AZ10 strains and shown in Figure 2, panel B. For cluster A: BSL2–2005 (SD 2005; GenBank accession no. DQ666452), BSL2–09 (NV 2009, JF957175), BSL4–11 (AZ 2011, JQ700438); cluster B: v4530 (NM 2005, HM756677), 144WG-AZ06PI (AZ 2006, GQ507482); cluster C: v4798 (NY 2004, HM756671), BSL3–10 (AZ 2010, JF957186), BSL2–10 (AZ 2010 JF957185), BSL23–11 (AZ 2011, JQ700440).
