  • Cyprinid Herpesvirus 3 Genesig Advanced
    Primerdesign TM Ltd Cyprinid herpesvirus 3 Pol gene for DNA polymerase genesig® Advanced Kit 150 tests For general laboratory and research use only Quantification of Cyprinid herpesvirus 3 genomes. 1 genesig Advanced kit handbook HB10.03.11 Published Date: 09/11/2018 Introduction to Cyprinid herpesvirus 3 Cyprinid herpesvirus 3 (CyHV3) is the causative agent of a lethal disease in common (Cyprinus carpio carpio) and Koi carp (Cyprnius carpio koi). It was discovered in the late 1990s and has rapidly spread worldwide among cultured common carp and ornamental koi. Previously known as koi herpesvirus, it has caused severe economic losses in the global carp industry with its spread being attributed to international trade. The virus is a member of the order Herepesvirales and family Alloherpesviridae. It has a linear, double stranded genome of approximately 295 kb in length consisting of a large central portion flanked by two 22 kb repeat regions. The genome encodes 156 open reading frames (ORFs) including 8 ORFs encoded by the repeat regions. The genome is packaged in an icosahedral capsid that is contained within viral glycoproteins and then a host derived lipid envelope, giving an overall virion of 170-200nm in diameter. At present, common and koi carp are the only species known to be affected by the virus. The viral particles are transmitted through faeces, sloughing of mucous and inflammatory cells, and secretions that are released into the water. The skin pores are the main source of entry and site of replication but the disease also spreads to the organs, particularly the kidneys. The viral particles are further spread when the carp come into contact with each other during grazing, spawning or when uninfected fish pick at the skin lesions of dead infected fish.

Vet Res (2016) 47:8 DOI 10.1186/s13567-015-0297-6 Veterinary Research RESEARCH ARTICLE Open Access Expression of immunogenic structural proteins of cyprinid herpesvirus 3 in vitro assessed using immunofluorescence Sean J. Monaghan1* , Kim D. Thompson1,2, James E. Bron1, Sven M. Bergmann3, Tae S. Jung4, Takashi Aoki5, K. Fiona Muir1, Malte Dauber3, Sven Reiche3, Diana Chee1,6, Shin M. Chong6, Jing Chen7 and Alexandra Adams1 Abstract Cyprinid herpesvirus 3 (CyHV-3), also called koi herpesvirus (KHV), is the aetiological agent of a fatal disease in carp and koi (Cyprinus carpio L.), referred to as koi herpesvirus disease. The virus contains at least 40 structural proteins, of which few have been characterised with respect to their immunogenicity. Indirect immunofluorescence assays (IFAs) using two epitope-specific monoclonal antibodies (MAbs) were used to examine the expression kinetics of two potentially immunogenic and diagnostically relevant viral antigens, an envelope glycoprotein and a capsid-associated protein. The rate of expression of these antigens was determined following a time-course of infection in two CyHV-3 susceptible cell lines. The results were quantified using an IFA, performed in microtitre plates, and image analysis was used to analyse confocal micrographs, enabling measurement of differential virus-associated fluorescence and nucleus-associated fluorescence from stacks of captured scans. An 8-tenfold increase in capsid-associated protein expression was observed during the first 5 days post-infection compared to a 2-fold increase in glycoprotein expres- sion. A dominant protein of ~100 kDa reacted with the capsid-associated MAb≤ (20F10) in western blot analysis.

    VM-149 Koi Herpesvirus Disease (KHVD)1 Kathleen H. Hartman, Roy P.E. Yanong, Deborah B. Pouder, B. Denise Petty, Ruth Francis-Floyd, Allen C. Riggs, and Thomas B. Waltzek2 Introduction Koi herpesvirus (KHV) is a highly contagious virus that causes significant morbidity and mortality in common carp (Cyprinus carpio) varieties (Hedrick et al. 2000, Haenen et al. 2004). Common carp is raised as a foodfish in many countries and has also been selectively bred for the ornamental fish industry where it is known as koi. The first recognized case of KHV occurred in the United Kingdom in 1996 (Haenen et al. 2004). Since then other cases have been confirmed in almost all countries that culture koi and/ or common carp with the exception of Australia (Hedrick et al. 2000; Haenen et al. 2004, Pokorova et al. 2005). This information sheet is intended to inform veterinarians, biologists, fish producers and hobbyists about KHV disease. What Is KHV? Figure 1. Koi with mottled gills and sunken eyes due to koi Koi herpesvirus (also known as Cyprinid herpesvirus 3; herpesvirus disease. Credit: Deborah B. Pouder, University of Florida CyHV3) is classified as a double-stranded DNA virus herpesvirus, based on virus morphology and genetics, and belonging to the family Alloherpesviridae (which includes is closely related to carp pox virus (Cyprinid herpesvirus fish herpesviruses). The work of Waltzek and colleagues 1; CyHV1) and goldfish hematopoietic necrosis virus (Waltzek et al. 2005, 2009) revealed that KHV is indeed a (Cyprinid herpesvirus 2; CyHV2).

Currently, most aspects of EEDV disease ecology remain unknown. In this study, we investigated EEDV shedding in experimentally challenged (intracoelomic injection) lake trout that were individually microchipped. In order to assess viral shedding, each infected fish was placed in individual static, aerated aquaria for a period of 8 h, after which the water was assessed for the presence of EEDV DNA using quantitative PCR. Water sampling was conducted every seven days for 93 days post-infection (pi), followed by additional sampling after one year. Results demonstrated that lake trout began shedding EEDV into the water as early as 9 days pi.

  • Non-Structural Protein Porf 12 of Cyprinid Herpesvirus 3 Is Recognized by the Immune System of the Common Carp Cyprinus Carpio
    Vol. 111: 269–273, 2014 DISEASES OF AQUATIC ORGANISMS Published October 16 doi: 10.3354/dao02793 Dis Aquat Org NOTE Non-structural protein pORF 12 of cyprinid herpesvirus 3 is recognized by the immune system of the common carp Cyprinus carpio Julia Kattlun, Simon Menanteau-Ledouble, Mansour El-Matbouli* Clinical Division of Fish Medicine, University of Veterinary Medicine, Veterinärplatz 1, 1210 Vienna, Austria ABSTRACT: Cyprinid herpesvirus 3 is an important pathogen and the causative agent of koi herpesvirus disease, which has been associated with mass mortalities in koi and common carp Cyprinus carpio. Currently, the only available commercial vaccine is an attenuated version of the virus. This has led to concerns about its risk to reversion to virulence. Furthermore, the vaccine is currently only available in Israel and the United States. In order to investigate the antigenic profile of the virus, western blot was performed using infected cell culture supernatant and sera from carp that had survived exposure to the virus. Only one antigen could be detected, and mass spec- trometry analysis identified the corresponding protein as ORF 12, a putative secreted tumour necrosis factor receptor homologue. In other herpesviruses, such proteins have been associated with the viral infectious process in a number of ways, including the entry into the host cell and the inhibition of apoptosis in infected cells. The reason why only one antigen could be detected during this study is unknown.

  • Herpes Virus Infection Associated with Interstitial Nephritis in a Beaked
    Arbelo et al. BMC Veterinary Research 2012, 8:243 http://www.biomedcentral.com/1746-6148/8/243 RESEARCH ARTICLE Open Access Herpes virus infection associated with interstitial nephritis in a beaked whale (Mesoplodon densirostris) Manuel Arbelo1, Edwige N Bellière2, Eva Sierra1, Simona Sacchinni1, Fernando Esperón2, Marisa Andrada1, Miguel Rivero1, Josue Diaz-Delgado1 and Antonio Fernández1* Abstract Background: The capacity for herpesvirus to cause disease in cetaceans is unclear and may be varied depending on the different conditions of individuals and between different species. Kidney pathology and intralesional virus-associated infection have been rarely reported in cetaceans. Result: On April 2004, an old adult male Blainville’s beaked whale (Mesoplodon densirostris) 420 cm long with a poor body condition was stranded on Tenerife Island. During necropsy, no gross lesions were observed in the kidneys. However, membranous glomerulonephritis, multifocal interstitial lymphoplasmacytic nephritis and acute multifocal necrotizing tubulointerstitial nephritis with intranuclear inclusion bodies was diagnosed by histological analysis. Tissue samples were submitted for bacteriological analysis and molecular viral screening. Conclusion: A novel alpha herpesvirus associated with interstitial nephritis was identified in an old adult male Blainville's beaked whale (M. densirostris) with a poor body condition stranded in the Canary Islands. This report suggests that identification of herpesvirus infection could be used as a differential diagnosis for interstitial nephritis in cetaceans.

  • Expression of Immune-Related Genes of Common Carp During Cyprinid Herpesvirus 3 Infection
    Vol. 113: 127–135, 2015 DISEASES OF AQUATIC ORGANISMS Published March 9 doi: 10.3354/dao02824 Dis Aquat Org Expression of immune-related genes of common carp during cyprinid herpesvirus 3 infection Agus Sunarto1,2, Kenneth A. McColl1,* 1CSIRO Biosecurity Flagship, Australian Animal Health Laboratory, Geelong, VIC 3220, Australia 2AMFRD Centre for Aquaculture Research and Development, Fish Health Research Laboratory, Jakarta 12540, Indonesia ABSTRACT: Fish herpesviruses and their hosts may have coevolved for 400 to 450 million yr. Dur- ing this coexistence, the hosts have equipped themselves with an elaborate immune system to defend themselves from invading viruses, whereas the viruses have developed strategies to evade host immunity, including the expression of cytokine genes that have been captured from the host. Taking advantage of our experimental model for cyprinid herpesvirus 3 (CyHV-3) persistence in carp, we studied the gene expression of host and virus immune-related genes in each stage of infection: acute, persistent and reactivation phases. IFNγ-1, IFNγ-2, IL-12 and IL-10 host genes, and the CyHV-3 vIL-10 gene (khvIL-10) were highly significantly up-regulated in different phases of CyHV-3 infection. Similarly, host IL-1β was up-regulated in the acute phase of CyHV-3 infec- tion. There was no significant difference in the expression of host TNFα-1 and MHC-II genes dur- ing all phases of CyHV-3 infection. Based on the expression profile of carp immune-related genes in each stage of CyHV-3 infection, we propose a possible interaction between carp IL-12, carp IL- 10 and khvIL-10 during the course of viral infection.
