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 Parvovirinae 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 originates from the natural recombination of strains ujs2665 and BSRI.
