“…As far as the serologic relationship between the viruses grouped in Table III is concerned, cross neutralization brought about no new points of view. No antigen in common to the various viruses could be revealed by such tests (Moore, 1962b;Portell a, 1963;Lum and Schreiner, 1963;Toolan, 1964;Crawford, 1966;Gorham et al, 1966;Johnson, 1967b;Johnson et ai., 1967;Scott et ai., 1970b;Cross and Parker, 1972;Storz et ai., 1972;Inaba et al, 1973b;Joo et al, 1975;Siegl, 1976;Tratschin et al, 1982). Slight antigenic differences between individual isolates of one and the same virus, however, apparently are more readily detected than by means of HI.…”

Differences in the pathogenesis of porcine parvovirus (PPV) were shown when pregnant gilts were infected by the oral and intramuscular (i.m.) routes. By the oral route, PPV took 23-32 days to cross the placenta following infection of the dam, as compared to 15 days by the i.m. route, Successful transplacental infection occurred following oral infection of dams only in the second third of gestation, whilst i.m. infection resulted in infection of foetuses in both first and second thirds of gestation. Foetal infection resulted in death and mummification only where infection of foetuses occurred before onset of immune competence--estimated at 70 days gestation. Infected foetuses either died before onset of immune competence, or survived to mount an immune response with subsequent death or survival to farrowing. It is suggested in discussion that reproductive failure due to PPV, characterised by mummification or occasional stillbirth, is associated in nature with oral infection, and occurs only when dams are infected in the first part of the midthird of gestation.

“…Isolation of PPV from fetal tissues and demonstration of antibody against PPV in fetal fluids was performed as described elsewhere (Serensen & Askaa 1981). Sera from the gilts were examined for antibody to PPV using the hemagglutination inhibition (HI) test (Joo et al 1975).…”
