The current situation of bovine virus diarrhoea-mucosal disease (BVD-MD) virus infections is briefly reviewed, with special reference to problems arising from fetal infection in the Hokkaido district, a northern island of Japan. The results of some investigations on BVD-MD virus carried out in Japan are also described. Although bovine congenital anomalies caused by BVD-MD virus and mucosal dise...

Bovine viral diarrhea (BVD) is one of the most important infectious diseases in cattle, causing major economic losses worldwide. Therefore, control programs have been implemented in several countries. In Germany, an obligatory nationwide eradication program has been in force since 2011. Its centerpiece is the detection of animals persistently infected (PI) with BVD virus, primarily based on the...

Our objective was to determine the prevalence of serum antibodies to bovine herpesvirus-1 (BHV-1) and bovine viral diarrhea (BVD) virus in beef cattle in Uruguay. A random sample of 230 herds selected with probability proportional to population size based on the number of cattle was chosen from a list frame of all registered livestock farms as of June 1999. Sera from up to 10 heifers, cows and ...

The prevalence of bovine viral diarrhoea (BVD) serologically positive animals in 18 dairy herds with clinical and pathological lesions suggestive of BVD infection, the post-vaccinal seroconversion rates in negative animals vaccinated twice with an inactivated BVD vaccine, and the control measures taken, are described. The pathological and histopathological findings in 6 necropsies performed on ...

A scenario tree model was developed to propose efficient bovine viral diarrhea (BVD) control measures. The model used field data in eastern Hokkaido where the risk of BVDV infection in cattle has been reduced by an eradication program including mass vaccination, individual tests prior to communal pasture grazing, herd screening tests using bulk milk, and outbreak investigations of newly infecte...

UNLABELLED Many previous studies have shown that lesions of the peripheral vestibular system result in spatial memory deficits and electrophysiological dysfunction in the hippocampus. Given the importance of glutamate as a neurotransmitter in the hippocampus, it was predicted that bilateral vestibular deafferentation (BVD) would alter the expression of NMDA and AMPA receptors in this area of th...

Bovine viral diarrhea disease is one of the viral diseases in cattle that were reported 10-90 percent in many countries. The causative RNA virus is a member of the family Flaviviridae and the genus pestivirus which is antigenically closely related with the virus of BD in sheep. Cattle are the most sensitive species to virus and are considered the principal reservoir of BVD viruses. A large prop...

Outbreaks of diarrhoea associated with mucosal erosions of the mouth, tongue and digestive tract, clinically diagnosed as bovine virus diarrhoea-mucosal disease (BVD-MD), have been reported in Argentina and Brazil since the 1960's. However, primary isolation of the virus of BVD-MD is fairly recent, occurring in 1974 for Brazil, 1984 for Argentina, 1985 for Chile and 1981 for Colombia. In Argent...

BACKGROUND In 2008, a program to eradicate bovine virus diarrhea (BVD) in cattle in Switzerland was initiated. After targeted elimination of persistently infected animals that represent the main virus reservoir, the absence of BVD is surveilled serologically since 2012. In view of steadily decreasing pestivirus seroprevalence in the cattle population, the susceptibility for (re-) infection by b...

Nine healthy pregnant does free from BVD neutralizing antibodies were I/V and I/P inoculated with two cytopathic strains of BVD virus (NADL-camel) at about 65 days of gestation. In NADL strain of BVDV group, abortion occurred in 3 out of 5 virus inoculated does on 7, 17 and 21 days post inoculation (PI) . The mean serum progesterone values of pregnant does significantly decreased on days 7(P<0....
