This is the first report of an acute and fatal outbreak of bovine diarrhea virus (BVDV)-2 infection in Israel. The clinical presentation varied with the age of the affected animals with a bovine-respiratory-complex-like syndrome in young stock, and diarrhea and dysentery only in the lactating stock. Enteritis first appeared in one shed of post-parturient cows; it spread for 6 weeks, until at le...

VirOligo is a database of virus-specific oligonucleotides. The VirOligo database consists of two tables, Common data and Oligo data. The Oligo data table contains PCR primers and hybridization probes used for detection of viral nucleic acids and the Common data table contains the experimental conditions used in their detection. Each oligonucleotide entry contains links to PubMed, GenBank, NCBI ...

Two bovine viral diarrhea virus (BVDV) fetal protection studies were done using a monovalent noncytopathic (NCP) BVDV vaccine containing type 1 BVDV. In study 1, thirty-two fetuses (23 vaccinates and nine controls) were recovered following fetal challenge with the type 1a BJ strain. Twenty of twenty-three fetuses from the vaccinates were negative for BVDV type 1 while all of the controls (nine ...

Background: To further minimize transmission risk of blood-borne viral and prion diseases, manufacturers of therapeutic animalor human-derived proteins have implemented improved in-process pathogen-removal procedures. Objectives: To evaluate removal of transmissible spongiform encephalopathy agents (prions) and viruses using Omega 100K VR membrane filtration system (Pall Filtron, Northborough, ...

Both type-1 and type-2 bovine viral diarrhea virus (BVDV) infections are responsible for major losses in the cattle industry. However, several commercial BVDV vaccines contain only a type-1 strain. A vaccine trial was conducted to evaluate the efficacy of BVDV type-1 (Singer strain; BVDV-1) vaccine for protecting calves challenged with virulent BVDV type-2 (890 strain; BVDV-2). Thirty-eight BVD...

Genetic selection in livestock offers the opportunity to improve bovine viral diarrhea virus (BVDV) vaccine response, but first we must define how vaccine response should be measured. For measuring humoral vaccine response, serum neutralization (SN) measures antibodies that can neutralize BVDV, but relative to enzyme-linked immunosorbent assay (ELISA) is time consuming, technically demanding, a...
