Farm studies of porcine parvovirus infection
Journal of the American Veterinary Medical Association, 1983SUMMARY Epizootics of reproductive failure associated with porcine parvovirus infection were investigated on 38 farms. Mummification was common to all epizootics. The mean number of mummified fetuses per affected litter was 3.1. Mean number of pigs born alive for gilts and sows farrowing litters with mummified fetuses was 5.0, but for sows without ...

Tissue tropisms of porcine parvovirus in swine
Archives of Virology, 1993Late-term gestation swine fetuses, similar to adult animals, are able to effectively mount immune response and survive porcine parvovirus (PPV) infection. An exception to this is the Kresse strain of PPV, which causes fetal death in late-term gestation swine fetuses.

An economic assessment of porcine parvovirus vaccination
Australian Veterinary Journal, 1993SUMMARY A decision analysis model was designed to evaluate the cost effectiveness of a vaccination program for preventing endemic or epidemic porcine parvovirus (PPV) Induced reproductive failure in a 100‐sow pig herd. The results showed that the cost of vaccination was less than the cost incurred by continuing endemic PPV infection, or the cost of a ...

Genital infection of pigs with porcine parvovirus
Journal of Comparative Pathology, 1974Abstract Experimental infection of sows with porcine parvovirus (strain 59e 63 ) is described. The virus was added to the semen immediately prior to artificial insemination and the sows were killed 30 d. later. Three out of 6 infected sows contained foetuses at 30 d. Of the 3 uninfected control sows 2 were pregnant.

Fetal Mummification Associated with Porcine Parvovirus Infection
Journal of the American Veterinary Medical Association, 1975SUMMARY A crossbred gilt farrowed 2 mummified fetuses at term, but subsequently developed uterine inertia and became listless. The remaining 5 fetuses of the litter (4 mummified and 1 normal appearing) were collected by hysterectomy. Porcine parvovirus (ppv) was isolated from tissues of the mummified fetuses, and masses of viral antigen were detected ...

Persistence of passive immunity to porcine parvovirus
Australian Veterinary Journal, 1985Maternally derived antibody to porcine parvovirus (PPV) has been shown to prevent the development of active immunity following infection or vaccination (Johnson et al 1976; Paul et aI1980).

Isolation of Porcine parvovirus from aborted piglets
New Zealand Veterinary Journal, 1977Summary The isolation of three strains of porcine parvovirus from aborted foetal piglets is recorded and the role of this virus as a cause of reproductive failure in pigs is discussed.

OBSERVATIONS ON THE EPIDEMIOLOGY OF PORCINE PARVOVIRUS
Australian Veterinary Journal, 1976SummaryEvidence presented suggests that porcine parvovirus is highly stable and infective. Introduction of virus to susceptible herds results in 100% infection rate within the following 3 months. Active immunity is associated with high persistent levels of haemagglutination‐inhibitating (HI) antibody (> 256), piglets suckling immune sows acquiring ...

Porcine parvovirus infection in a commercial piggery
New Zealand Veterinary Journal, 1986Abstract Extract Madam:– We have recently been involved in a consultative role with a 60-sow commercial piggery. Over the year preceding the incident recorded here, this unit had approximately doubled in size by the purchase of improved large white gilts.
