Mol Cell Probes 2019; 46:101412. [PMID: 31201852 DOI: 10.1016/j.mcp.2019.06.002] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2019] [Revised: 05/31/2019] [Accepted: 06/11/2019] [Indexed: 12/12/2022]
Abstract
Lineage 2 West Nile virus (WNV) strains have been implicated in severe encephalitis outbreaks in humans and equines residing in Europe. WNV molecular characterization is important for the development of diagnostic assays, as well as for obtaining molecular information, which is necessary for epidemiological investigations of virus transmission in areas at risk. For whole genome sequencing of lineage 2 WNV strains, directly from biological specimens, a PCR-based NGS protocol was developed. The method was applied in WNV-positive specimens obtained from animal, human and mosquito hosts in Greece. The results of its application indicate that, even in cases of low virus titers, the developed PCR-based NGS approach is able to provide whole genome sequences of lineage 2 WNV strains.

Abstract
The emergence of novel arboviruses of zoonotic potential in South Africa (SA) threatens human health and animal welfare, and affects economic growth and development. These viruses cause severe infections in animals and humans, including neurological diseases, such as encephalitis, resulting in high morbidities, mortalities and economic losses. With increasing reports of Middelburg, Shuni, Sindbis, West Nile and Wesselsbron virus infections in animals and humans in SA, this article reviews and discusses known and currently emerging arboviruses in the country. These reports underscore the need for increased surveillance, vector control management, public health preparedness, focused research, community awareness programs, and the development of rapid and sensitive diagnostic approaches. Furthermore, appropriate medical personnel training and strengthening initiatives for a one-health approach are required to understand and mitigate the emerging arboviral threat to public health.

First isolation of West Nile virus in Zambia from mosquitoes. Transbound Emerg Dis 2018; 65:933-938.

Abstract
Mosquito surveillance studies to identify mosquito-borne flaviviruses have identified West Nile Virus (WNV) for the first time in Zambia. The Zambian WNV isolate from Culex quinquefasciatus mosquitoes collected in the Western Province was closely related genetically to WNV lineage 2 South African strains which have been previously shown to be highly neuroinvasive. These data provide the first evidence of the circulation of WNV in Zambia and suggest there should be an increased awareness of possible associated human and animal diseases in that country.
