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 ...

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.

Role of the rat in the transmission of porcine parvovirus
American Journal of Veterinary Research, 1982SUMMARY Rats experimentally inoculated with porcine parvovirus (ppv) shed virus in excreta from 3 to 21 days. Rats inoculated subcutaneously with ppv responded serologically with hemagglutination-inhibition titers (512-1,024). The ppv antigen was readily detected in lung and spleen 2 and 3 days after rats were inoculated and in liver and intestine, 4 ...

Transplacental Infection of Piglets with a Porcine Parvovirus
Research in Veterinary Science, 1971Summary When gilts at various stages of gestation were infected orally with a porcine parvovirus, transplacental infection of the foetus occurred at stages of gestation up to 80 days, without significant effect on the subsequent litter. Specific antibody was present in the pre-suckle serum of piglets from gilts infected between 58 and 80 days ...

Outbreaks of porcine parvovirus disease in Panama
Tropical Animal Health and Production, 1991The first recorded isolation of porcine parvovirus (PPV) in Panama is described. The outbreaks of PPV disease were characterised by a high prevalence of mummified foetuses, stillborn and weak pigs and a common source of exposure. Diagnosis was based on virus isolation and by demonstrating viral antigen in lungs of affected foetuses.

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 ...

A microneutralization test for the assay of porcine parvovirus antibody
Archives of Virology, 1975A microplate test was developed for the determination of neutralizing antibody titers against porcine parvovirus. End points were read directly by using haemagglutination techniques. The test was proved to be highly sensitive and reproducible.

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.

Restriction of porcine parvovirus replication in nonpermissive cells
Journal of Virology, 1992Swine testicle (ST) cells and Madin-Darby canine kidney (MDCK) cells differ in their ability to support replication of porcine parvovirus (PPV). Viral replication events in ST cells, a permissive cell type, and MDCK cells, a nonpermissive cell type, were compared in an attempt to elucidate putative mechanisms of restrictive virus replication ...
