| identification and genomic characterization of a novel porcine parvovirus (ppv6) in china. | parvoviruses are classified into two subfamilies based on their host range: the parvovirinae, which infect vertebrates, and the densovirinae, which mainly infect insects and other arthropods. in recent years, a number of novel parvoviruses belonging to the subfamily parvovirinae have been identified from various animal species and humans, including human parvovirus 4 (parv4), porcine hokovirus, ovine partetravirus, porcine parvovirus 4 (ppv4), and porcine parvovirus 5 (ppv5). | 2014 | 25442288 |
| what is for dinner? viral metagenomics of us store bought beef, pork, and chicken. | we describe here the metagenomics-derived viral sequences detected in beef, pork, and chicken purchased from stores in san francisco. in beef we detected four previously reported viruses (two parvoviruses belonging to different genera, an anellovirus, and one circovirus-like virus) and one novel bovine polyomavirus species (bpyv2-sf) whose closest relatives infect primates. detection of porcine hokovirus in beef indicated that this parvovirus can infect both ungulate species. in pork we detected ... | 2014 | 25217712 |
| development of a loop-mediated isothermal amplification assay for the detection of porcine hokovirus. | hokoviruses have recently been detected as pathogens belonging to the family parvoviridae, which comprises porcine hokovirus (phov) and bovine hokovirus (bhov). in this study, we developed a loop-mediated isothermal amplification (lamp) assay for the rapid, specific and sensitive detection of phov. a set of four primers specific for six regions within the phov vp1/2 genes was designed using online software. the reaction temperature and time were optimized at 65°c and 60 min, respectively. lamp p ... | 2013 | 23850717 |
| first identification of porcine parvovirus 6 in north america by viral metagenomic sequencing of serum from pigs infected with porcine reproductive and respiratory syndrome virus. | currently, eight species in four genera of parvovirus have been described that infect swine. these include ungulate protoparvovirus 1 (classical porcine parvovirus, ppv), ungulate tetraparvovirus 2 (ppv3), ungulate tetraparvovirus 3 (which includes ppv2, porcine hokovirus, porcine partetravirus and porcine parv4), ungulate copiparvovirus 2 (which includes ppv4 and ppv5), ungulate bocaparvovirus 2 (which includes porcine bocavirus 1, 2 and 6), ungulate bocaparvovirus 3 (porcine bocavirus 5), ungu ... | 2015 | 26475593 |
| prevalence of porcine hokovirus and its co-infection with porcine circovirus 2 in china. | here, we report the frequency of porcine hokovirus (phov) infection and its co-infection with porcine circovirus 2 (pcv2) in china. a total of 485 domestic pig samples were tested for both phov and pcv2, and ns1 gene sequences from 11 phov strains were used for phylogenetic analysis. the prevalence of phov and pcv2 was 51.3 % and 36.3 %, respectively, and co-infection occurred in 20.2 %. phovs from the chinese mainland showed a close relationship to those isolated in hong kong. co-infection with ... | 2013 | 23558802 |
