Characterization of Three Novel Viruses from the Families Nyamiviridae, Orthomyxoviridae, and Peribunyaviridae, Isolated from Dead Birds Collected during West Nile Virus Surveillance in Harris County, Texas

This report describes and characterizes three novel RNA viruses isolated from dead birds collected during West Nile virus surveillance in Harris County, TX, USA (the Houston metropolitan area). The novel viruses are identified as members of the families Nyamaviridae, Orthomyxoviridae, and Peribunyaviridae and have been designated as San Jacinto virus, Mason Creek virus, and Buffalo Bayou virus, respectively. Their potential public health and/or veterinary importance are still unknown.

The objective of this paper was to characterize the role of the current West Nile Virus (WNV) surveillance in supporting the identification of and public health preparedness for other emerging mosquito-borne diseases in Canada. We systematically reviewed publicly accessible WNV surveillance records published within the federal, provincial (n = 10), territorial (n = 3), and regional health authorities (n = 95) between 2000 and 2016. We describe the strategic approaches and activities to WNV surveillance from 124 websites, four public health databases, and three custom Google search engines. WNV surveillance in Canada can address emerging mosquito-borne diseases. However, surveillance practices are likely to underestimate the true risks. Prioritizing and strengthening WNV surveillance by all levels of the Canadian Government through timely surveillance measures, consistent and representative data for accurate prediction of trends and risks are recommended.

This study reports on a fatal case of a captive great grey owl infected with the West Nile virus (WNV) in the zoological garden Košice, eastern Slovakia (Central Europe). The tissue samples of the dead owl were used for virus isolation and genetic characterization. The novel isolate is genetically closer to Hungarian, Greek, and Bulgarian strains from the central/southern European clade of lineage 2 than to the strains previously isolated in Slovakia. Interestingly, it carries NS3-249P, a molecular virulence determinant associated with higher neurovirulence, which has not previously been observed in Slovakia. Subsequent serological investigation of the captive owls revealed additional seropositive animals, indicating local WNV transmission. Although no WNV-positive mosquitoes were found, the presence of the WNV principal vector Culex pipiens complex together with the described fatal case and further serological findings indicate an endemic focus of bird-neurovirulent WNV variant in the area.
