Biology of Porcine Parvovirus (Ungulate parvovirus 1)
Porcine parvovirus (PPV) is among the most important infectious agents causing infertility in pigs. Until recently, it was thought that the virus had low genetic variance, and that prevention of its harmful effect on pig fertility could be well-controlled by vaccination. However, at the beginning of the third millennium, field observations raised concerns about the effectiveness of the availabl...
متن کاملLesions resulting from inoculation of porcine foetuses with porcine parvovirus.
In utero inoculation of 15 sows at various stages of gestation with a local strain of porcine parvovirus (PPV) resulted in resorption, abortion or the birth of weak, dead, or mummified foetuses. Histopathological lesions observed in foetuses of sows slaughtered at various post-inoculation intervals consisted of a perivascular inflammatory reaction primarily observed in the brain and kidneys. Th...
متن کاملIsolation of porcine parvovirus from commercial trypsin.
The isolation of porcine parvovirus from a lot of commercial 1:250 trypsin is reported and the method is described.
متن کاملPerspectives on the Evolution of Porcine Parvovirus
Porcine parvovirus (PPV) is one of the main causes of porcine reproductive failure. It is important for swine industries to understand the recent trends in PPV evolution. Previous data show that PPV has two genetic lineages originating in Germany. In this study, two more genetic lineages were defined, one of which was distinctly Asian. Additionally, amino acid substitutions in European strains ...
متن کاملThe effect of porcine parvovirus and porcine reproductive and respiratory syndrome virus on porcine reproductive performance.
From a worldwide perspective, porcine parvovirus (PPV) and porcine reproductive and respiratory syndrome virus (PRRSV) are the most common viral causes of porcine reproductive failure. A typical epidemic of PPV-induced reproductive failure is presented as an increased number of mummified fetuses and sometimes, entire litters are mummified. If infection with PPV is very early in gestation, the n...
