Figure. Maximum-likelihood phylogenetic trees of severe acute respiratory syndrome coronavirus 2 from 3 Malayan tigers, Virginia, USA. Tiger samples are numbered in order of symptom onset. A) Subset of phylogenetic tree showing parent (G23236T) and grandparent (C4900T) nodes of the tiger sequences, with tips labeled as states of origin in the United States or Australia. B) Phylogenetic tree showing that other B.1.1.7 viruses detected in Virginia that contain the K558N mutation are not epidemiologically related to the sequences detected in tigers 1, 2, and 3. SNP, single-nucleotide polymorphism.
