Determination and analysis of the complete genome sequence of Paralichthys olivaceus rhabdovirus (PORV).

Paralichthys olivaceus rhabdovirus (PORV), which is associated with high mortality rates in flounder, was isolated in China in 2005. Here, we provide an annotated sequence record of PORV, the genome of which comprises 11,182 nucleotides and contains six genes in the order 3′-N-P-M-G-NV-L-5′. Phylogenetic analysis based on glycoprotein sequences of PORV and other rhabdoviruses showed that PORV clusters with viral haemorrhagic septicemia virus (VHSV), genus Novirhabdovirus, family Rhabdoviridae. Further phylogenetic analysis of the combined amino acid sequences of six proteins of PORV and VHSV strains showed that PORV clusters with Korean strains and is closely related to Asian strains, all of which were isolated from flounder. In a comparison in which the sequences of the six proteins were combined, PORV shared the highest identity (98.3 %) with VHSV strain KJ2008 from Korea. [ABSTRACT FROM AUTHOR]
