Transplacental transmission of bovine adenoviruses.

Type 1 bovine adenovirus has been isolated from cell cultures prepared from the kidneys of a 7-month-old bovine fetus, taken from a slaughterhouse, and types 4, 6 and 8 from cell cultures prepared from the testicles of four neonatal, precolostral calves. Sera of these precolostral calves possessed virus-neutralizing antibodies in titers of 1:4--1:16. Bovine adenoviruses of types 4 and 8 have also been isolated from two bovine fetuses aborted from an unknown cause. Relying upon these findings the possible vertical (transplacental) transmission of bovine adenoviruses is presumed. Though a cause-and-effect relationship between abortion and adenovirus infection could not be detected, it is probably that infection during fetal development cannot be indifferent to the fetus or the neonatal calf.

Adenoviridae.

The elevation of the genus Adenovirus to a family named Adenoviridae is described. This family at the present stage contains two genera, mammalian adenoviruses--Mastadenovirus--and avian adenoviruses--Aviadenovirus. The two genera are separated primarily on the basis of difference in immunological properties of the virions.
