Bovine pestivirus infection: a cause of ovulatory disturbance in dairy cows

  Twelve (Experiment I) and four (Experiment II) multiparous dairy cows seronegative to pestivirus were selected and randomly assigned to either a control group which did not become infected or a treatment group in which all cows became infected following intranasal inoculation 9 days before AI. The experimental induction of infection was carried out with 2 ml of non-cytopathic pestivirus (BVD ...

Serological survey of pestivirus infection of small ruminants in Ahvaz, Iran

In order to study the seroprevalence of pestivirus infection in small ruminants of Ahvaz at Khouzestan province of Iran, 148 sheep sera and 143 goat sera were randomly collected and tested by seroneutralization. Seroneutralization was performed by NADL strain of Bovine viral diarrhea virus genotype 1. The results indicated the overall seroprevanelces of 46.62% in sheep and 32.871% in goats. Pre...

Transmission of border disease virus from a persistently infected calf to seronegative heifers in early pregnancy

BACKGROUND This study describes the transmission of border disease virus (BDV) from a persistently infected calf to seronegative heifers in early pregnancy, resulting in persistently infected fetuses. On day 50 of pregnancy (= day 0 of the infection phase), six heifers were co-housed in a free stall with a bull calf persistently infected with BDV (pi BVD) for 60 days. The heifers underwent dail...
