Molecular detection of a novel cyprinid herpesvirus in roach (Rutilus rutilus) and asp (Leuciscus aspius) showing typical signs of carp pox disease
Archives of Virology, 2020Co-Authors: Boglárka Sellyei, Ferenc Baska, Ádám Varga, Réka Borzák, Andor DoszpolyAbstract:In the early spring of 2018, in Lake Balaton (Hungary), a roach ( Rutilus rutilus ) and an asp ( Leuciscus aspius ) were found in an fish trap at the outlet of the river Sió showing typical signs of the so-called carp pox disease, such as foci of epidermal hyperplasia on the head and the whole body surface, including the fins. Molecular tests revealed the presence of the DNA of an unknown fish herpesvirus. Three genes encoding the DNA-dependent DNA polymerase, major capsid protein and ATPase subunit of terminase were amplified and sequenced from the alloherpesviral genome. The gene sequences of the viruses obtained from the two different fish species shared 94.4% nucleotide sequence identity (98.1% amino acid sequence identity), suggesting that they belong to the same virus species. Phylogenetic analysis based on the DNA polymerase (and the concatenated sequences of the amplified genes, as well) implied that the detected virus belongs to the genus Cyprinivirus within the family Alloherpesviridae . The sequences of the novel alloherpesvirus diverge from those of the five Cyprinivirus species described previously, so it putatively represents the sixth virus species in the genus.

Molecular detection of a putatively novel cyprinid herpesvirus in sichel (Pelecus cultratus) during a mass mortality event in Hungary
Archives of Virology, 2015Co-Authors: Andor Doszpoly, Melitta Papp, Petra P. Deákné, Róbert Glávits, Krisztina Ursu, Ádám DánAbstract:In the early summer of 2014, mass mortality of sichel ( Pelecus cultratus ) was observed in Lake Balaton, Hungary. Histological examination revealed degenerative changes within the tubular epithelium, mainly in the distal tubules and collecting ducts in the kidneys and multifocal vacuolisation in the brain stem and cerebellum. Routine molecular investigations showed the presence of the DNA of an unknown alloherpesvirus in some specimens. Subsequently, three genes of the putative herpesviral genome (DNA polymerase, terminase, and helicase) were amplified and partially sequenced. A phylogenetic tree reconstruction based on the concatenated sequence of these three conserved genes implied that the virus belongs to the genus Cyprinivirus within the family Alloherpesviridae . The sequences of the sichel herpesvirus differ markedly from those of the Cypriniviruses CyHV-1, CyHV-2 and CyHV-3, putatively representing a fifth species in the genus.

Comparative analysis of a conserved gene block from the genome of the members of the genus ictalurivirus.
Intervirology, 2011Co-Authors: Andor Doszpoly, Mária Benko, G. Bovo, Scott E. Lapatra, Balázs HarrachAbstract:Objective: Partial genome sequences were determined and subjected to comparative analyses from two fish herpesviruses (HVs). Acipenserid (Aci) HV-2, originating from the white sturgeon (Acipenser transmontanus), and ictalurid (Ic) HV-2, isolated from the black bullhead (Ameiurus melas), are recently approved species of the genus Ictalurivirus of the family Alloherpesviridae. Methods: An almost 8,000-base-pair fragment, spanning between the genes of the DNA polymerase and the ATPase subunit of the terminase, was sequenced from each virus. Results: The size, position and orientation of 2 partial and 3 full open reading frames, contained in the studied genome fragment, proved to be similar to their counterparts in IcHV-1, the type species of the genus Ictalurivirus. Thus, a well-conserved genus-specific gene block was identified. In the members of two other genera (Cyprinivirus and Batrachovirus) of the family Alloherpesviridae, no such gene block could be found; the location and orientation of the homologous genes showed significant divergence. Conclusion: The results of phylogenetic calculations were in good agreement with the genome arrangements inasmuch as AciHV-2, IcHV-1 and -2 are monophyletic and separated from the lineages of the other two genera. The new sequence enabled the inclusion of a hitherto unassigned HV, that of the Australian pilchard, into a phylogenetic calculation.
