Protocol for the Production of Doubled Haploid Plants of Brassica carinata.

Brassica carinata, also known as Ethiopian or Abyssinian mustard, is a drought- and heat-tolerant oilseed with great potential as a dedicated industrial feedstock crop for use in biofuel and other bio-based applications. Doubled haploid technology, a system that allows for the rapid development of doubled haploid, completely homozygous plants through microspore embryogenesis, has been applied routinely in both B. carinata breeding and basic research.

No evidence of PEDV infection in French artificial insemination centers in 2015.

Pigs infected by porcine epidemic diarrhea virus (PEDV) are affected by severe diarrhea, vomiting and dehydration. The severity of clinical signs depends on the virus strain. Two genetically different PEDV strains are known to infect pigs, the PEDV S-InDel strains which circulate on all continents and the highly virulent PEDV S-non-InDel strains found in Asia and in America.

Limited shedding of an S-InDel strain of porcine epidemic diarrhea virus (PEDV) in semen and questions regarding the infectivity of the detected virus.

PEDV is mainly transmitted by the oro-fecal route although PEDV shedding in semen has already been shown for an S-non-InDel PEDV strain infection. The aim of this study was to determine if PEDV can be shed in semen from SPF (specific pathogens free) boars infected by a French S-InDel PEDV strain (PEDV/FR/001/2014) and in case of positive semen to determine the infectivity of that semen. Both infected boars had diarrhea after inoculation and shed virus in feces.

Evidence of porcine epidemic diarrhea virus (PEDV) shedding in semen from infected specific pathogen-free boars.

In 2013, PED emerged for the first time in the United States (US). The porcine epidemic diarrhea virus (PEDV) spread quickly throughout North America. Infection with PEDV causes watery diarrhea and up to 100% mortality in piglets, particularly for highly pathogenic non-InDel strains circulating in the US.

Evidence of excretion of Schmallenberg virus in bull semen.

Schmallenberg virus (SBV) is a novel orthobunyavirus, discovered in Germany in late 2011. It mainly infects cattle, sheep and goats and could lead to congenital infection, causing abortion and fetal abnormalities. SBV is transmitted by biting midges from the Culicoides genus and there is no evidence that natural infection occurs directly between ruminants.
