Abstract

In the present study, we have cloned and sequenced the nearly-full-length genome of minute virus of canines (MVC), SH26, in China. The genome of MVC, 5,132 nucleotides (nts) in length, contains three open reading frames (ORFs), which are 2,325-bp of NS1, 561-bp of NP1 and 2,112-bp of VP1/VP2 encoding three proteins of 774, 186 and 703 residues, respectively. Predicted amino acids sequence of NS1 of MVC has 44% identity with human bocavirus (HBoV) and human boacvirus 2 (HBoV2), NP1 has 48 and 45% identity with HBoV and HBoV2, VP1/VP2 has 45 and 46% identity with HBoV and HBoV2, respectively. Phylogenetic analysis showed that the present Chinese MVC strain was also closely clustered with the previous American and Japanese MVC isolates, and MVCs formed a different branch together with bovine parvovirus and HBoVs from other parvoviruses classified into Parvovirinae.
