Cds46, a highly variable carp edema virus gene.

ABSTRACT: Carp edema virus disease (CEVD) is a severe viral illness that causes substantial economic losses in wild and farmed common carp and koi. It is caused by carp edema virus (CEV), a member of the Poxviridae family, whose genetic diversity and genome evolution are poorly understood. Based on a genomic fragment of the 4a gene, two genogroups, genogroup I (gI) and genogroup II (gII), have been identified in samples of different origins. By analysing a series of recent samples, we highlight here a new genomic region of interest that varies by substitutions, indels and putative recombinations. In the Japanese reference sequence, this region encodes an ORF, cds46, whose function is unknown despite weak homologies with genes of some members of the Iridoviridae. Surprisin
