Ungulate copiparvovirus 1 (bovine parvovirus 2): characterization of a new genotype and associated viremia in different bovine age groups

A novel bovine parvovirus 2 (BPV2) genotype comprising 5394 nt was identified by next generation sequencing from sera of healthy cattle at different age groups farmed in the state of Rio Grande do Sul, Brazil. The genome organization of new BPV2 genotype retains the two ORFs typical of members of the Parvovirinae with 86.4 % of overall nucleotide sequence identities in comparison to other members of the subfamily. Phylogenetic analysis revealed similar clustering with two previously described bovine BPV2 within the genus Copiparvovirus. No significant differences (P a parts per thousand yen 0.05) were detected in the distribution of BPV2 infection in cattle at different age groups. This is the third complete or near complete genome sequence of BPV2 reported to date and may contribute to a better understanding of the biology of copiparvoviruses and its interactions with the host.
