A virus was isolated from uterine exudate of a cow and later identified as a herpesvirus that had no serologic relationship to several known viruses. The virus produced a febril response in 7 month old Holstein steers. Inoculation of the virus into bovine fetuses of various gestational ages resulted in death of some fetuses in the 3rd and 4th months of gestation. Some fetuses in the 3rd and 4th month, and all older than 4 months, survived the inoculation. These fetuses experienced a lymphoreticular activation and a humoral antibody response.
