Introduction
This is the first in a series of videos which will explore how to control and prevent Bovine Viral Diarrhoea. This video comprises an introduction to the series by the recognised expert in the field Professor Joe Brownlie and past President of the BVA David Catlow.
BVD - The Virus
This film on the BVD Virus is split into three parts. The first part introduces the members of the Pestivirus family. The second part deals with the genomic structure and the individual genes and their products. The third part explains how the different biotypes are formed and the relationship to the diseases caused by the virus.
In this video, we want to explain the relevance and importance of the molecular structure of the virus and to show the reason why we get different isolates of different virulence on different farms. The BVD virus is an RNA virus which is single stranded and shows a great capacity to mutate. The consequence of this is that we are constantly faced with viruses of different virulence and also viruses that have different fingerprints. This can present problems for diagnostics, but, on the positive side, it does allow us to identify different isolates on different farms. We hope this video will shed some light on the virus and why a better understanding of it will help in selecting the correct diagnostics and interpreting their results.
