Equine influenza A(H3N8) virus isolated from Bactrian camel, Mongolia

Myagmarsukh Yondon et al. Emerg Infect Dis. 2014 Dec.

Abstract

Because little is known about the ecology of influenza viruses in camels, 460 nasal swab specimens were collected from healthy (no overt illness) Bactrian camels in Mongolia during 2012. One specimen was positive for influenza A virus (A/camel/Mongolia/335/2012[H3N8]), which is phylogenetically related to equine influenza A(H3N8) viruses and probably represents natural horse-to-camel transmission.

Evolutionary relationships of 155 full-length hemagglutinin sequences from equine A(H3N8)viruses collected globally and A/camel/Mongolia/335/2012 (arrow). The 2 clades associated with most recent equine influenza A(H3N8) viruses, Florida clade 1 and Florida clade 2, are denoted as FC1 and FC2, respectively, and with nomenclature adopted previously (13). The maximum-likelihood tree is midpoint rooted for clarity, and all branch lengths are drawn to scale. High (>70) bootstrap values are provided for key nodes. Hemagglutinin sequences containing a 2aa insertion are identified with a solid black circle. Scale bar indicates nucleotide substitutions per site.
