BVD Type 1b
- Responsible for the majority of persistent infections
- Type 1b isolates can be included as a killed virus vaccine alone or in a combination
- Not contained in commercial MLV vaccines
Bovine Viral Diarrhea Virus Type 1b Subunit Vaccine Induces Neutralizing Antibodies in Calves
Bovine viral diarrhea virus (BVDV) type 1b is widespread and the predominate type circulating in the U.S. cattle population. Recent studies have demonstrated that limited or no cross neutralizing activity occurred when using antisera generated against types 1a, 1b and 2 BVDV. At the present time, most of the commercial vaccines do not appear to induce protection against type 1b strains of BVDV. In this study, we evaluated a type 1b BVDV subunit vaccine for its ability to induce neutralizing antibody.
BVD PI Testing: Ear Notching Suggestions
Confusion during the sampling process can produce inaccurate BVD PI testing results, and sometimes no results at all. See our tips and suggestions for collecting good samples and increasing diagnostic test accuracy.
