SARS-CoV-2 B.1.1.7 Variant Infection in Malayan Tigers, Virginia, USA

Patrick K Mitchell et al. Emerg Infect Dis. 2021 Dec.

Abstract

We report infection of 3 Malayan tigers with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) B.1.1.7 (Alpha) variant at a zoologic park in Virginia, USA. All tigers exhibited respiratory signs consistent with SARS-CoV-2 infection. These findings show that tigers are susceptible to infection with the SARS-CoV-2 B.1.1.7 variant.

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.
