Using Cell Lines to Study Factors Affecting Transmission of Fish Viruses
Using cell lines to study factors affecting transmission of fish viruses by Phuc Hoang Pham A thesis presented to the University of Waterloo in fulfillment of the thesis requirement for the degree of Doctor of Philosophy in Biology Waterloo, Ontario, Canada, 2014 ©Phuc Hoang Pham 2014 AUTHOR'S DECLARATION I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. ii ABSTRACT Factors that can influence the transmission of aquatic viruses in fish production facilities and natural environment are the immune defense of host species, the ability of viruses to infect host cells, and the environmental persistence of viruses. In this thesis, fish cell lines were used to study different aspects of these factors. Five viruses were used in this study: viral hemorrhagic septicemia virus (VHSV) from the Rhabdoviridae family; chum salmon reovirus (CSV) from the Reoviridae family; infectious pancreatic necrosis virus (IPNV) from the Birnaviridae family; and grouper iridovirus (GIV) and frog virus-3 (FV3) from the Iridoviridae family. The first factor affecting the transmission of fish viruses examined in this thesis is the immune defense of host species. In this work, infections of marine VHSV-IVa and freshwater VHSV-IVb were studied in two rainbow trout cell lines, RTgill-W1 from the gill epithelium, and RTS11 from spleen macrophages. RTgill-W1 produced infectious progeny of both VHSV-IVa and -IVb. However, VHSV-IVa was more infectious than IVb toward RTgill-W1: IVa caused cytopathic effects (CPE) at a lower viral titre, elicited CPE earlier, and yielded higher titres. -

Ceratopogonidae (genus Culicoides) are well-known vectors of several viruses responsible for epizooties (bluetongue, epizootic haemorrhagic disease, etc.). They are also vectors of the only known virus infecting humans: the Oropouche virus. Female midges usually feed on a variety of hosts, leading to possible transmission of emerging viruses from animals to humans. -
Characterization of Farmington Virus, a Novel Virus from Birds That Is Distantly Related to Members of the Family Rhabdoviridae
Palacios et al. Virology Journal 2013, 10:219 http://www.virologyj.com/content/10/1/219 RESEARCH Open Access Characterization of Farmington virus, a novel virus from birds that is distantly related to members of the family Rhabdoviridae Gustavo Palacios1†, Naomi L Forrester2,3,4†, Nazir Savji5,7†, Amelia P A Travassos da Rosa2, Hilda Guzman2, Kelly DeToy5, Vsevolod L Popov2,4, Peter J Walker6, W Ian Lipkin5, Nikos Vasilakis2,3,4 and Robert B Tesh2,4* Abstract Background: Farmington virus (FARV) is a rhabdovirus that was isolated from a wild bird during an outbreak of epizootic eastern equine encephalitis on a pheasant farm in Connecticut, USA. Findings: Analysis of the nearly complete genome sequence of the prototype CT AN 114 strain indicates that it encodes the five canonical rhabdovirus structural proteins (N, P, M, G and L) with alternative ORFs (> 180 nt) in the N and G genes. Phenotypic and genetic characterization of FARV has confirmed that it is a novel rhabdovirus and probably represents a new species within the family Rhabdoviridae. Conclusions: In sum, our analysis indicates that FARV represents a new species within the family Rhabdoviridae.

Received: 17 December 2019; Accepted: 9 January 2020; Published: 14 January 2020 Abstract: White spot syndrome virus (WSSV), the lone virus of the genus Whispovirus under the family Nimaviridae, is one of the most devastating viruses affecting the shrimp farming industry. Knowledge about this virus, in particular, its evolution history, has been limited, partly due to its large genome and the lack of other closely related free-living viruses for comparative studies. In this study, we reconstructed a full-length endogenous nimavirus consensus genome, Nimav-1_LVa (279,905 bp), in the genome sequence of Penaeus (Litopenaeus) vannamei breed Kehai No. 1 (ASM378908v1). This endogenous virus seemed to insert exclusively into the telomeric pentanucleotide microsatellite (TAACC/GGTTA)n. It encoded 117 putative genes, with some containing introns, such as g012 (inhibitor of apoptosis, IAP), g046 (crustacean hyperglycemic hormone, CHH), g155 (innexin), g158 (Bax inhibitor 1 like). -

To date, most studies of DNA viruses have focused on those with the strongest disease associations. Accordingly, there has been a marked lack of sampling of DNA viruses from invertebrates. Bulk RNA sequencing has resulted in the discovery of a myriad of novel RNA viruses, and herein we used this methodology to identify actively transcribing DNA viruses in meta-transcriptomic libraries of diverse invertebrate species. Our analysis revealed high levels of phylogenetic diversity in DNA viruses, including 13 species from the Parvoviridae, Circoviridae, and Genomoviridae families of single-stranded DNA virus families, and six double-stranded DNA virus species from the Nudiviridae, Polyomaviridae, and Herpesviridae, for which few invertebrate viruses have been identified to date. -

Several viruses have Virome been tentatively associated to such syndrome. Here, in order to examine potential associations between enteric Broiler chickens viruses and MAS, the faecal viromes of 70 stool samples collected from diseased (n = 35) and healthy (n = 35) High-throughput sequencing chickens from seven flocks were characterized and compared. Following high-throughput sequencing, a total of 8,347,319 paired end reads, with an average of 231 nt, were generated. Through analysis of de novo assembled contigs, 144 contigs > 1000 nt were identified with hits to eukaryotic viral sequences, as determined by GenBank database.
