Abstract
A criti ca 1 revi ew of the 1 i terature back to the 18th century revealed that abortion in cattle infected with rinderpest virus has received scant attention despite a handful of early reports of its occurrence. These early reports have been confirmed; three strains of the virus of varying degrees of virulence induced abortion in cattle while attenuated vaccine strains did not. Over 50 per cent of the abortions occurred 2 to 7 weeks following clinical recovery and most foetuses aborted at this stage showed virological and antigenic evidence of in utero transplacental infection with the virus. Foetuses aborted during or soon after the acute stage of the disease had no demonstrable evi dence of transp 1 acenta 1 infection. Some cows did not abort and delivered normal calves at term, a few of which had pre-colostral serum neutralizing antibodies against rinderpest virus indicating in utero infection.
