“…Transplacental infection with the current European strain of BTV-8 has been investigated extensively in both sheep and cattle in experimental Backx et al, 2009;van der Sluijs et al, 2011) and field studies (De Clercq et al, 2008;Darpel et al, 2009a;SantmanBerends et al, 2010;Saegerman et al, 2010) in north-western Europe. Field surveys have indicated that the virus was extremely efficient at crossing the placenta.…”

The capability of the current European strain of bluetongue virus serotype 8 (BTV-8) to cross the ruminant placenta has been established in experimental and field studies in both sheep and cattle. Sero-prevalence rates in goats in north-western Europe were high during the recent outbreak of BTV-8, however the capability of the virus to infect goats through the transplacental route has not been established. In the present study, four Saanen goats pregnant at 62 days of gestation were inoculated with the European strain of BTV-8, in order to investigate the capability of the virus to cross the caprine placenta. Infection of adult goats resulted in mild clinical signs, however gross lesions observed post mortem were more severe.

“…The BTV-8 strain also demonstrated the ability to cross the ruminant placenta a (Backx et al, 2009;Darpel et al, 2009;De Clerq et al, 2008;Desmecht et al, 2008;Menzies et al, 2008;Saegerman et al, 2010;van der Sluijs et al, 2011;Vercauteren et al, 2008), a property that had previously only generally been associated with the vaccination of pregnant animals with MLV strains (Flanagan and Johnson, 1995;Parsonson et al, 1987;Schultz and Delay, 1955).. The BTV-8 strain also appears to have had an increased tendency to be secreted in the semen of infected rams and bulls.…”

“…Contact transmission of BTV has been suspected in WTD (Thomas and Trainer 1970) and cattle (Menzies et al 2008). Transplacental transmission of BTV has been demonstrated in Europe in cattle (Backx et al 2009) and sheep (Worwa et al 2009), but the epidemiological importance of these alternate routes has not been well investigated.…”

Bluetongue virus (BTV) and epizootic hemorrhagic disease virus (EHDV) are arthropod-transmitted viruses in the genus Orbivirus of the family Reoviridae. These viruses infect a variety of domestic and wild ruminant hosts, although the susceptibility to clinical disease associated with BTV or EHDV infection varies greatly among host species, as well as between individuals of the same species. Since their initial detection in North America during the 1950s, these viruses have circulated in endemic and epidemic patterns, with occasional incursions to more northern latitudes. In recent years, changes in the pattern of BTV and EHDV infection and disease have forced the scientific community to revisit some fundamental areas related to the epidemiology of these diseases, specifically in relation to virus-vector-host interactions and environmental factors that have potentially enabled the observed changes. The aim of this review is to identify research and surveillance gaps that obscure our understanding of BT and EHD in North America.
