Frequency detection of porcine circovirus-like viruses in pigs with porcine respiratory disease

Veterinary Microbiology, 2022
The emergence of the circular replication-associated protein (Rep) encoding single-stranded (CRESS) DNA viruses in different hosts has been associated with serious diseases, such as porcine diarrhea. The prevalence and pathogenicity of porcine circovirus-like virus (Po-Circo-like virus (PCLV)), a member of CRESS DNA virus, has not been fully ...

In utero transmission of porcine torque teno viruses

Veterinary Microbiology, 2009
Sera and selected tissue homogenates collected from gnotobiotic swine never exposed to the environment or other swine tissues were tested for the presence of porcine torque teno virus (TTV) DNAs by nested and non-nested polymerase chain reactions (PCR) using primers specific for the untranslated region of porcine genogroups (g) 1 and 2. Twenty-three of

The structure of porcine parvovirus: comparison with related viruses

Journal of Molecular Biology, 2002
The structure of baculovirus-expressed porcine parvovirus (PPV) capsids was solved using X-ray crystallography and was found to be similar to the related canine parvovirus (CPV) and minute virus of mice (MVM). The PPV capsid protein has 57 % and 49 % amino acid sequence identity with CPV and MVM, respectively, but the degree of conservation of surface ...

Emergence of novel porcine reproductive and respiratory syndrome viruses (ORF5 RFLP 1-7-4 viruses) in China.

Veterinary Microbiology, 2018
Porcine reproductive and respiratory syndrome viruses (PRRSVs) pose a serious threat to the porcine industry of China, and the importation of novel strain(s) makes it challenging to control these viruses. Several NADC30-like PRRSV outbreaks have occurred

Biologic and immunologic properties of porcine type C viruses

Virology, 1975
Six different porcine cell lines spontaneously begin to release type C viruses after long-term propagation in vitro. Reverse transcriptases from all of the viral isolates are inhibited by immune IgG directed against the polymerase from the endogenous porcine type C virus PK(15).

Can human viruses infect porcine xenografts?

Xenotransplantation, 2010
Xenotransplantation exposes the recipient to known and unknown pathogens of the donor pig (donor-derived xenosis). A major effort has been undertaken to minimize the risk of transmission from the donor using specialized breeding techniques. With the exception of endogenous retroviruses and porcine lymphotropic herpesvirus, exclusion of known pathogens ...

Susceptibility of porcine preimplantation embryos to viruses associated with reproductive failure

Theriogenology, 2016
In the modern biological area, the applications of pig as a laboratory model have extensive prospects, such as gene transfer, IVF, SCNT, and xenotransplantation. However, the risk of pathogen transmission by porcine embryos is always a topic to be investigated, especially the viruses related to reproductive failure, for instance, pseudorabies virus ...

The interferon sensitivity of selected porcine viruses.

Canadian journal of veterinary research = Revue canadienne de recherche veterinaire, 1989
The objective of this study was to compare the sensitivity of 11 porcine viruses to the antiviral effects of porcine interferon-alpha in serum from piglets which had been infected 19 h previously with transmissible gastroenteritis virus, and of porcine interferon-beta prepared in PK-15 cells by induction with polyinosinic:polycytidylic acid, in yield ...

[Clinical detection of seven porcine diarrhea-associated viruses and evolution analysis of porcine kobuvirus].

Sheng wu gong cheng xue bao = Chinese journal of biotechnology, 2018
In this study, a multiplex RT-PCR method was developed for detection of seven diarrhea-associated porcine viruses, including porcine teschovirus (PTV), porcine sapovirus (PSV), porcine deltacornavirus (PDCoV), porcine kobuvirus (PKV), porcine sapovirus (PSaV), porcine astrovirus (PAstV) and porcine torovirus (PToV). A total of 419 samples were screened
