title: Embryo transfer as a means of controlling the transmission of viral infections. VIII. Failure to detect foot-and-mouth disease viral infectivity associated with embryos collected from infected donor cattle.
abstract: Foot-and-mouth disease (FMD) viral infectivity detectable in cell cultures or by animal inoculation was not found to be associated with any of 48 washed zona pellucida-intact (ZPI) embryos collected from 8 cattle during the acute stages of disease. Similarly, infectivity was not found to be associated with any of 42 washed ZPI embryos collected from 3 cattle 21 d after infection with FMD.
