Summary: | Duck enteritis virus (DEV) is a herpesvirus that causes an acute, contagious, and fatal disease. In the present article, the DEV
UL5 gene was cloned and sequenced from a vaccine virus. According to the consensus sequence of herpesvirus
UL5 and
UL3 gene degenerate oligonucleotide primers were designed and were used in the polymerase chain reaction (PCR) to amplify DNA products with 4577
bp in size. DNA sequence analysis revealed a 2568
bp open reading frame (ORF) encoding a 855 amino acid polypeptide homologous to herpesvirus UL5 proteins. The DEV
UL5 gene has a base composition of 769 adenine (29.95%), 556 cytosine (21.65%), 533 guanine (20.76%) and 710 thymine (27.65%). Sequence comparison revealed that the nucleotide sequence of the DEV
UL5 gene was highly similar to other alphaherpesviruses. Phylogenetic tree analysis showed that the fifteen herpesviruses viruses analyzed fell into four large groups, and the duck enteritis virus itself branched and was most closely related to meleagrid herpesvirus 1, gallid herpesvirus 2 and gallid herpesvirus 3 subtrees. |
