“…It was only known to infect rainbow trout until the end of 1980's. Since then VHS was reported in various marine fishes in Europe (Mortensen et al, 1999;Schlotfeldt, 1991), including anadromous salmon (Winton et al, 1989) and marine fish in North America (Meyers and Winton, 1995;Smail, 1999). VHSV detected also in the Great Lakes region of North America (Elsayed et al, 2006) and North Atlantic coast of Canada (Gagne et al, 2007 wide range of wild marine species in Japan, Europe and North America (Hedrick et al, 2003;Mortensen et al, 1999;Takano et al, 2000).…”

Existence of viral hemorrhagic septicemia virus (VHSV) has been recently reported in Turkey. A total of 5967 marine and freshwater fish were sampled to detect VHSV between 2007 and 2009 in the Black Sea region of Turkey. Of the 5967 fish, five fish tested positive by PCR reactions of tissue filtrates and supernatants of cell cultures showing CPE indicated by a specific 587 bp fragments from the glycoprotein (G) gene of VHSV. All the VHSV positive fish were turbots and none of the other fish species was VHSV positive. The nucleotide sequences among five isolates had shown 96% to 99% homology. In the phylogenetic study, all the new isolates were genogroup 1e. In this study, it was also discovered that an IPNV-VHSV mixed infected wild turbot.

Piscine novirhabdovirus = Viral Hemorrhagic Septicemia Virus (VHSV) first appeared in the Laurentian Great Lakes with large outbreaks from 2005 to 2006, as a new and novel RNA rhabdovirus subgenogroup (IVb) that killed >30 fish species. Interlude periods punctuated smaller more localized outbreaks in 2007, 2010, and 2017, although some fishes tested positive in the intervals. There have not been reports of outbreaks or positives from 2018, 2019, or 2020. Here, we employ a combined population genetics and phylogenetic approach to evaluate spatial and temporal evolutionary trajectory on its G‐gene sequence variation, in comparison with whole‐genome sequences (11,083 bp) from a subset of 44 individual isolates (including 40 newly sequenced ones). Our results show that IVb (N = 184 individual fish isolates) diversified into 36 G‐gene haplotypes from 2003 to 2017, stemming from two originals (“a” and “b”). G‐gene haplotypes “a” and “b” differed by just one synonymous single‐nucleotide polymorphism (SNP) substitution, remained the most abundant until 2011, then disappeared. Group “a” descendants (14 haplotypes) remained most prevalent in the Upper and Central Great Lakes, with eight (51%) having nonsynonymous substitutions. Group “b” descendants primarily have occurred in the Lower Great Lakes, including 22 haplotypes, of which 15 (68%) contained nonsynonymous changes. Evolutionary patterns of the whole‐genome sequences (which had 34 haplotypes among 44 isolates) appear congruent with those from the G‐gene. Virus populations significantly diverged among the Upper, Central, and Lower Great Lakes, diversifying over time. Spatial divergence was apparent in the overall patterns of nucleotide substitutions, while amino acid changes increased temporally. VHSV‐IVb thus significantly differentiated across its less than two decades in the Great Lakes, accompanied by declining outbreaks and virulence. Continuing diversification likely allowed the virus to persist at low levels in resident fish populations, and may facilitate its potential for further and future spread to new habitats and nonacclimated hosts.
