Key result
Encephalomyocarditis virus inoculation in pregnant sows causes transplacental infection and fetal death in ~42% of fetuses.
Why the study?
The ability of encephalomyocarditis virus to cause transplacental infection and fetal death in pregnant sows was investigated.
Comparison
EMCV passaged 4 times on BHK-21 cells vs EMCV passaged 5 additional times in pigs
Design
Experimental inoculation study
Follow-up
Up to 44 days postinoculation

Pig-passaged EMCV causes transplacental fetal infection and death in sows; leaves open questions on natural transmission and control in commercial herds.
Experimental inoculation of pregnant sows with pig-passaged encephalomyocarditis virus causes transplacental infection and fetal death.
Christianson et al. (1992) studied Encephalomyocarditis virus (EMCV) infection in pregnancy (n=10). Encephalomyocarditis virus (EMCV) inoculation was evaluated on Transplacental infection and fetal death. Inoculation of pregnant sows with pig-passaged encephalomyocarditis virus resulted in transplacental infection and fetal death in 20 of 48 fetuses by day 28 postinoculation.
