Bovine Virus Diarrhoea Virus, a Cause of Early Pregnancy Failure in the Cow

Abstract: Summary In the present report attention is drawn to clinical and hormonal changes in heifers following experimental or natural infection with bovine virus diarrhoea virus in early pregnancy. Three heifers were infected experimentally and one naturally at pregnancy stages from 29–41 days. A leukopenia was seen 5–7 days after infection. All four animals experienced foetal death. Two of them aborted and in two the foetus was resorbed. Oestrus was observed at the expulsion of the foetus or in connection with vagin… Show more

“…It can be transmitted vertically and produce malformations and microcephaly in calves [27][28][29][30][31][32][33][34]. Its horizontal transmission is done by body fluids, including milk, saliva and fomites [27][28][29][30][31][32][33][34].…”

“…167 Of four heifers infected between 29 and 41 days of pregnancy, two abortions and two fetal resorptions were observed. 168 While infections in the preimplantation phase (before day 40 of pregnancy) result in large numbers of pregnancy losses, fetuses that survive infection with noncytopathic BVDV of low to moderated virulence from approximately 40 to 125 days become PI. 169,170 Persistent infections can only occur with noncytopathic BVDV strains, and experimental infections with cytopathic isolates do not result in the development of PI calves.…”
