Comparative studies of border disease and closely related virus infections in experimental pigs and sheep.

ABSTRACT

A pestivirus originally isolated from weaner pigs was shown to be capable of infecting weaners experimentally, but without inducing significant signs of disease. When inoculated into pregnant sows and ewes in early gestation, both the porcine virus and an antigenically similar ovine border disease isolate could induce congenital infections in both species.
