D.  aStudies on maternal transmission of scrapie in sheep by embryo transfer.h[electronic resource]  c1992  aAbstract: The technique of embryo transfer was used to investigate the maternal transmission of scrapie in sheep. Embryo donor ewes were experimentally infected with scrapie (all aventually developing the disease) and artificially inseminated six months later with semen from an uninfected scrapie-susceptible ram. Embryos were harvested five and six days after insemination and transferred by laparoscopy, unwashed, into recipient ewes which had been genetically selected for very low susceptibility to scrapie. Six of the 26 lambs born to these recipients developed scrapie.  aDisease transmission  aEmbryo transfer  aFemales  aPregnancy complications  aScrapie  aSheep  aDoença animal  aOvino  aPeste de cocar  aTransferência de embrião  aOvary microbiology  aParaplegia endêmica  aSpongiform encephalopathy  aTransmissão1 aMcKELVEY, W.
