Abstract

We detected Middle East respiratory syndrome coronavirus (MERS-CoV) RNA in 305/1,131 (27%) camels tested at an abattoir in Al Hasa, Eastern Province, Saudi Arabia, during January 2016-March 2018. We characterized 48 full-length MERS-CoV genomes and noted the viruses clustered in MERS-CoV lineage 5 clade B.

Keywords: MERS; MERS-CoV; Middle East respiratory syndrome; Saudi Arabia; abattoir; camels; coronavirus; dromedary; phylogeny; respiratory infections; viruses; zoonoses.

Phylogeny of Middle East respiratory syndrome coronavirus (MERS-CoV) sequenced from nasal and rectal samples collected from camels in an abattoir, Saudi Arabia. Phylogeny was constructed by using IQTREE (http://www.iqtree.org) with the automatic nucleotide transition model selection. Branch supports, shown at major nodes, were generated by ultrafast bootstrap approximation (Appendix). Genomes generated from this study are underlined; asterisks (*) indicate viruses from humans. Blue indicates viruses from camels from Saudi Arabia; red indicates viruses in camels imported from Sudan; green indicates viruses in camels imported from Somalia. The overall topology of the phylogeny of MERS-CoV also is available (Appendix Figure). Scale bar indicates 104 mutations per site.
