Maternal antibody to porcine parvovirus usually prevents active infection and seconversion before ____ months of age.

What happens when a non-pregnant pig gets infected with porcine parvovirus:
No negative consequences - clinical signs are not observed, and infection results in lasting immunity
If parvovirus infection occurs in less than 30 days of gestation, what are the consequences:
Embryonic death and resorbtion - return to estrus
If parvovirus infection occurs in less than 12 days of gestation - will return to estrus be delayed?
No - becuase maternal recognition of fetus does not occur until 12 days or later.
Porcine parvovirus between 30-70 days in gestation:
fetal death and mummification
porcine parvovirus infection great than 70 days of gestation:
fetal immune response and survival to term - possibly weak or stillborn
Easiest way to confirm that mummification was due to parvo virus:
Fluorescent antibody test on mummified fetus
Is serology helpful in diagnosing porcine parvovirus?
No, many pigs will become infected with parvovirus throughout their lifetime, and there is also a vaccine.
Vaccination against porcine parvovirus is _____ recommended, and will ____ epidemic pregnancy loss due to the virus, however may still have ____ incidence of endemic loss.
- Commonly
- prevent
- low
