Identification of a recombinant isolate of ungulate copiparvovirus

Identification of a recombinant isolate of ungulate copiparvovirus To evaluate the status of parvovirus infection in free-range cows in a region of northeast China, nine serum samples were collected and analysed by sequencing and polymerase chain reaction.

Abstract

To evaluate the status of parvovirus infection in free-range cows in a region of northeast China, nine serum samples were collected and analysed by sequencing and polymerase chain reaction. A new bovine parvovirus-2 (BPV2) was identified and named QQHE16. The genome of the virus is 5759 nucleotides long and retains two ORFs that are typical of the Parvoviri- nae family. Compared with reference BPV2 strains, BPV2 QQHE16 appeared to have a close relationship with strain BSRI isolated in the USA in 2013. A putative recombination breakpoint located at nucleotide position 2121 and in the interval between the non-structural gene and the VP gene was identified. From our analysis, we propose that strain QQHE16 origi- nates from the natural recombination of strains ujs2665 and BSRI.
