Embryo transfer as a means of controlling viral infections. VI. Bluetongue virus-free calves from infectious semen.
TLDR
It is suggested that B TV-free calves can be readily obtained from the use of BTV-positive semen and their embryos accounted for 9 of the 10 pregnancies including the six surviving calves.About:

Journal ArticleDOI
The dangers of disease transmission by artificial insemination and embryo transfer
TL;DR: The evidence for and against the possibility of infectious agents being transmitted between animals via the venereal route or by the use of semen or early embryos in commercial artificial insemination (AI) or embryo transfer (ET) is presented.
Journal ArticleDOI
Evaluation of risks of viral transmission to recipients of bovine embryos arising from fertilisation with virus-infected semen
TL;DR: This scientific review was prompted by recent legislation to curtail the use of semen from potentially virus-infected bulls to produce embryos for import into the European Union, finding that there is a potential, at least, that in vivo-derived embryos resulting from infected semen might carry BVDV, although field studies so far suggest that this is very unlikely.
Journal ArticleDOI
The disease control potential of embryos
TL;DR: Analysis of this data emphasizes the importance of the integrity of the zona pellucida and of proper washing of embryos to ensure infectious disease control.
Book ChapterDOI
Pathology and pathogenesis of bluetongue infections.
TL;DR: Bluetongue disease is an infectious, noncontagious, arthropod-borne viral disease, mostly of sheep, but also of other ruminants (Erasmus 1975).

Embryo transfer as a means of controlling the transmission of viral infections. I. The in vitro exposure of preimplantation bovine embryos to akabane, bluetongue and bovine viral diarrhea viruses
TL;DR: Initial experiments were undertaken to determine the virus susceptibility of early embryos, and no infectious virus was isolated from any of the embryos and the in vitro development of virus exposed embryos proceeded normally.
Journal Article
Epizootiologic study of bluetongue: virologic and serologic results.
TL;DR: Heparinized blood and serum samples were obtained from 1,295 ruminants in herds or flocks with bluetongue virus (BTV) infection in 4 western states and viral isolations were seasonal, occurring from August until December.

Journal ArticleDOI
The search for viruses in bovine semen, a review.
TL;DR: The widespread distribution of frozen semen, an ideal system for preserving viral infectivity, indicates this product could serve as an important vehicle for transmission of viruses to unin infected herds or areas.

Embryo transfer as a means of controlling the transmission of viral infections. IV. Non-transmission of infectious bovine rhinotracheitis/infectious pustular vulvovaginitis virus following trypsin treatment of exposed embryos
TL;DR: Virus isolation and histopathology on both abortuses, the stillborn calves, and three calves slaughtered at three months of age were negative for IBRV.
