文摘In this paper,a 1,860 bp sequence in IRs region of duck enteritis virus(DEV) was amplified by single oligonucleotide nested PCR with a single primer designed according to partial sequence of US1 and then a pair of primers designed according to the 3' UTR of US8 gene and 5' end of the new getting sequence were used to amplify a 2,426 bp sequence toward the TRs region.Sequence analysis revealed that the both sequences contained an identical 990 bp open reading frame of DEV US1 gene.The two ORFs were in opposite transcription orientation.Sequence comparison of the nucleotide sequence and the deduced amino acid sequence of US1 gene showed relatively high identity to Mardivirus.Phylogenetic tree analysis showed that the eleven herpesviruses viruses were classified into three groups,and the duck enteritis virus was most closely related to Mardivirus.
