Abstract

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.
