Bovine Viral Diarrhoea
Introduction
Bovine Viral Diarrhoea Virus (BVDV) infections can have significant and serious implications to the milk and meat production industry. The presence of the virus can cause spontaneous abortions in cows or result in the transplacental spread of the virus to newborn calves, making them persistently infected (PI). The presence of maternal antibodies during testing can interfere with the detection of the BVD-Virus (shielding). As a result, unidentified PI animals can remain in the herd and can spread the infection to other cattle. When PI animals are unidentified, the success of a BVDV farm control or eradication program can be greatly endangered.
The course of BVDV infection depends on the state of the affected animal (immunity, gestation) as well as on the virus strain causing the infection. The classic, acute form of Bovine Viral Diarrhoea (BVD) includes symptoms such as diarrhoea, fever, anorexia, nasal and eye discharge and erosions in the oral cavity, on the muzzle, on the vaginal mucosa as well as in the interdigital cleft.
BVDV belongs to the genus Pestivirus of the family Flaviviridae. BVD has a world-wide distribution, and is characterized by high prevalence and relatively low morbidity. All age groups are susceptible.
Human health risk
There are no known risks to human health from this disease.
Economic impact
The BVD virus can have significant and serious implications to the milk and meat production industry. An outbreak of the virus can impact cattle herds in the following ways: fertility problems, spontaneous abortions, secondary infections, reduced feed intake and weight gain, and even animal deaths.
Diagnostic solution
Prionics has developed a complete PI-animal detection system which combines traceability with early detection of BVDV and is supported by a fully integrated software solution. This unique system now enables easy, effective, and early removal of persistently infected animals from a herd.
