Most infectious cause of fetal mummification

Porcine Parvovirus

2

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

4

3

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 

4

If parvovirus infection occurs in less than 30 days of gestation, what are the consequences:

Embryonic death and resorbtion - return to estrus

5

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.

6

Porcine parvovirus between 30-70 days in gestation:

fetal death and mummification

7

porcine parvovirus infection great than 70 days of gestation:

fetal immune response and survival to term - possibly weak or stillborn

8

Easiest way to confirm that mummification was due to parvo virus:

Fluorescent antibody test on mummified fetus

9

Is serology helpful in diagnosing porcine parvovirus?

No, many pigs will become infected with parvovirus throughout their lifetime, and there is also a vaccine.

10

Vaccination against porcine parvovirus is _____ recommended, and will ____ epidemic pregnancy loss due to the virus, however may still have ____ incidence of endemic loss.

3rd

13

Subclinical infection in pigs are not zoonotic. True or False.

False - they may be zoonotic 

14
