A canine parainfluenza virus type 5 strain was isolated from a lung sample from a diseased dog. The genome sequene of this isolate, named HeN0718, was determined and compared tho those of other previously reported canine parainfluenza viruses. Unlike previously reported viruses, the HeN0718 strain contained several nucleotide mutations in the SH gene that led to a frame shift in the open reading frame. Phylogenetic analysis based on the complete virus genome and the P, F, and HN genes showed that HeN0718 was genetically closest to D277, a Korean strain that was isolated in 2008.
