Abstract

Here, we present the complete genomic sequence of duck enteritis virus (DEV) strain SD, isolated in China in 2012. The virus was virulent in experimentally infected 2-month-old ducks. The DEV SD genome is 160,945 base pairs (bp) in length. The viral genome sequence, when compared to that of strain DEV CSC, which was isolated in 1962, showed three discontinuous deletions of 101 bp, 48 bp and 417 bp within the inverted repeats. A comparison of the amino acid (aa) sequences of all ORFs of the CSC and SD isolates demonstrated an11-aa deletion, two single-aa deletions, and one single-aa deletion in LORF3, UL47, UL4, respectively. Moreover, 38 single aa variations were also detected in 24 different ORFs. These results will further advance our understanding of the genetic variations involved in evolution.
