Identificação do vírus da Diarréia Viral Bovina tipo 2 (BVDV-2) no sul do Brasil [PDF]

Pesquisa Veterinária Brasileira, 2000
Amostras do vírus da Diarréia Viral Bovina (BVDV), denominadas de BVDV tipo 2 (BVDV-2), foram inicialmente identificadas em surtos de BVD aguda e enfermidade hemorrágica e têm sido isoladas predominantemente na América do Norte.

Sequence-optimised E2 constructs from BVDV-1b and BVDV-2 for DNA immunisation in cattle [PDF]

Veterinary Research, 2007
We report DNA immunisation experiments in cattle using plasmid constructs that encoded glycoprotein E2 from bovine viral diarrhoea virus (BVDV)-1 (E2.1) and BVDV-2 (E2.2). The coding sequences were optimised for efficient expression in mammalian cells.

Novel BVDV-2 mutants as new candidates for modified-live vaccines

Veterinary Microbiology, 2010
Protection against Bovine viral diarrhea virus (BVDV) type 2 infection of commercially available vaccines is often limited due to marked genetic and antigenic differences between BVDV types 1 (BVDV-1) and 2 (BVDV-2). Therefore, the immunogenicity of selected BVDV-1 and BVDV-2 mutants derived from infectious full-length cDNA clones and their use as ...

Cross-Neutralization between Bovine Viral Diarrhea Virus (BVDV) Types 1 and 2 after Vaccination with a BVDV-1a Modified-Live-Vaccine

Vaccines, 2023
Control of Bovine Viral Diarrhea Virus types 1 and 2 (BVDV-1 and BVDV-2) involves removing persistently infected animals from the herd, ensuring the biosecurity level of the farms and vaccination for the prevention of fetal infection.

In vitro method to evaluate virus competition between BVDV-1 and BVDV-2 strains using the PrimeFlow RNA assay [PDF]

Virology, 2019
Bovine viral diarrhea viruses (BVDV), segregated in BVDV-1 and BVDV-2 species, lead to substantial economic losses to the cattle industry worldwide. It has been hypothesized that there could be differences in level of replication, pathogenesis and tissue tropism between BVDV-1 and BVDV-2 strains.

Additional file 7 of Th17 cell differentiation induced by cytopathogenic biotype BVDV-2 in bovine PBLCs

, 2021
Additional file 7: Figure S2. Overexpression of IL17A inhibited the replication of GS2018. The Expression of IL17A and BVDV-2 E2 were detected by western blot in PBLCs at 24 h, 48 h and 72 h after GS2018 infection, respectively. The band of IL17A (a), BVDV-2 E2 (b, c) and GAPDH (d) protein were cropped horizontally from the same membrane before ...

Characterization of <i>Pestivirus tauri</i> (BVDV-2, Subtype c) Isolates in Northern Italy Using Whole-Genome Sequencing. [PDF]

Viruses
Bovine viral diarrhea (BVD) is a major cause of economic losses in the global cattle industry, particularly in countries characterized by intensive livestock production systems. Pestivirus tauri, formerly known as Bovine viral diarrhea virus type 2 (BVDV-2), is the current taxonomic designation according to the International Committee on Taxonomy of ...

First study on genetic variability of bovine viral diarrhea virus isolated from Sapera dairy goats with reproductive disorders in Yogyakarta, Indonesia [PDF]

Veterinary World, 2022
Background and Aim: Bovine viral diarrhea (BVD) virus (BVDV) is an important viral pathogen of cattle that can infect diverse artiodactyl species. The clinical manifestations caused by BVDV in heterologous hosts, as they do in cattle, vary, although ...
