R. of China 5West Pomeranian Technical University, Aquaculture, K. Królewicza 4, 71-550, Szczecin, Poland Abstract Most diseases induced by herpesviruses are host-specific; however, exceptions exist within the family Alloherpesviridae. Most members of the Alloherpesviridae are detected in at least two different species, with and without clinical signs of a disease. In the current study the Koi herpesvirus (KHV) was used as a model member of the Alloherpesviridae and rainbow trout as a model salmonid host, which were infected with KHV by immersion. KHV was detected using direct methods (qPCR and semi-nested PCR) and indirect (enzyme-linked immunosorbant assay; ELISA, serum neutralization test; SNT). The non-koi herpesvirus disease (KHVD)-susceptible salmonid fish were demonstrated to transfer KHV to naïve carp at two different temperatures including a temperature most suitable for the salmonid (15°C) and cyprinid (20°C). -
Fish Herpesvirus Diseases
ACTA VET. BRNO 2012, 81: 383–389; doi:10.2754/avb201281040383 Fish herpesvirus diseases: a short review of current knowledge Agnieszka Lepa, Andrzej Krzysztof Siwicki Inland Fisheries Institute, Department of Fish Pathology and Immunology, Olsztyn, Poland Received March 19, 2012 Accepted July 16, 2012 Abstract Fish herpesviruses can cause significant economic losses in aquaculture, and some of these viruses are oncogenic. The virion morphology and genome organization of fish herpesviruses are generally similar to those of higher vertebrates, but the phylogenetic connections between herpesvirus families are tenuous. In accordance with new taxonomy, fish herpesviruses belong to the family Alloherpesviridae in the order Herpesvirales. Fish herpesviruses can induce diseases ranging from mild, inapparent infections to serious ones that cause mass mortality. The aim of this work was to summarize the present knowledge about fish herpesvirus diseases. Alloherpesviridae, CyHV-3, CyHV-2, CyHV-1, IcHV-1, AngHV-1 Herpesviruses comprise a numerous group of large DNA viruses with common virion structure and biological properties (McGeoch et al. 2008; Mattenleiter et al. 2008). They are host-specific pathogens. Apart from three herpesviruses found recently in invertebrate species, all known herpesviruses infect vertebrates, from fish to mammals (Davison et al. 2005a; Savin et al. 2010). According to a new classification accepted by the International Committee on Taxonomy of Viruses (http:/ictvonline.org), all herpesviruses have been incorporated into a new order named Herpesvirales, which has been split into three families. The revised family Herpesviridae contains mammalian, avian, and reptilian viruses; the newly-created family Alloherpesviridae contains herpesviruses of fish and amphibians, and the new family Malacoherpesviridae comprises single invertebrate herpesvirus (Ostreid herpesvirus). -

Abstract: Anguillid herpesvirus 1 (AngHV-1) is a pathogen of eels and a member of the genus Cyprinivirus in the family Alloherpesviridae. We have compared the biological and genomic fea- tures of different AngHV-1 strains, focusing on their growth kinetics in vitro and genetic content, diversity, and recombination. Comparisons based on three core genes conserved among alloher- Citation: Donohoe, O.; Zhang, H.; pesviruses revealed that AngHV-1 exhibits a slower rate of change and less positive selection than Delrez, N.; Gao, Y.; Suárez, N.M.; other cypriniviruses. We propose that this may be linked to major differences in host species and Davison, A.J.; Vanderplasschen, A. -
