Establishment of a Bovine Viral Diarrhea Virus Type 2 Intranasal Challenge Model for Assessing Vaccine Efficacy

Frontiers in Veterinary Science, 2018
The objective of this study was to develop a bovine viral diarrhea virus type 2 (BVDV-2) challenge model suitable for evaluation of efficacy of BVDV vaccines; a model that mimics natural infection and induces clear leukopenia and viremia.

The consequences of host heterogeneity for parasite transmission depend on how host infectiousness is determined

Journal of Animal Ecology, EarlyView.
This study proposes two contrasting scenarios for how host infectiousness is determined: recipient dependence and donor dependence. These scenarios fundamentally alter how host heterogeneity shapes parasite transmission, demonstrating that the process by which infectiousness is determined is crucial for understanding the consequences of host ...

Pestivirus infection in cattle dairy farms: E2 glycoprotein ELISA reveals the presence of bovine viral diarrhea virus type 2 in northwestern Italy

BMC Veterinary Research, 2017
Background Bovine viral diarrhea virus (BVDV) types 1 and 2 are members of the Pestivirus genus of the Flaviviridae family. This genus also includes the HoBi-like virus, tentatively classified as BVDV type 3. BVDV-1 is widely distributed in Italy despite

Key insights into biosecurity risks, communication preferences and behaviour change drivers among livestock transporters in Australia

Australian Veterinary Journal, EarlyView.
The transportation of livestock poses an increased risk of disease transmission, with transportation vehicles acting as vectors for disease. Biosecurity management within the livestock industry is therefore critical to reduce the risk of disease transmission. This study investigated the current biosecurity practices of stakeholders within the livestock

Enfermidade gastroentérica e respiratória em bezerros inoculados com amostras brasileiras do vírus da diarréia viral bovina tipo 2 (BVDV-2) [PDF]

Ciência Rural, 2002
Duas amostras brasileiras do vírus da Diarréia Viral Bovina tipo 2 (BVDV-2) foram inoculadas em bezerros com o objetivo de avaliar a sua virulência e estudar a patogenia da infecção. Previamente à inoculação, os animais foram imunodeprimidos com dexametasona. Quatro bezerros com idades entre 45 e 90 dias (grupo A) foram inoculados com a amostra SV-260 (

Perfil genotípico e antigênico de amostras do vírus da diarréia viral bovina isoladas no Rio Grande do Sul (2000-2010)

Pesquisa Veterinária Brasileira, 2011
Isolados do vírus da diarréia viral bovina (BVDV) apresentam grande diversidade genética e antigênica, o que pode dificultar o diagnóstico e a formulação de vacinas.

PD-1 Blockade Restores the Proliferation of Peripheral Blood Lymphocyte and Inhibits Lymphocyte Apoptosis in a BALB/c Mouse Model of CP BVDV Acute Infection

Frontiers in Immunology, 2021
Acute infection of bovine viral diarrhea virus (BVDV) is associated with immune dysfunction and can cause peripheral blood lymphopenia and lymphocyte apoptosis.

Seroprevalence and Presumed Bovine Leukaemia Virus and Coxiella burnetii Coinfections in Three Dairy Cattle Herds From the Al Ain Region, United Arab Emirates

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
ABSTRACT Background Bovine leukaemia virus (BLV) and Coxiella burnetii are important infectious pathogens of dairy cattle with potential implications for animal health, productivity and zoonotic transmission (in the case of C. burnetii). Because BLV may alter immune function, we hypothesize that infection with the virus could increase cattle ...

Anticorpos neutralizantes contra o vírus da Diarréia Viral Bovina (BVDV): comparação entre um imunógeno experimental atenuado e três vacinas comerciais inativadas Vaccination-induced neutralizing antibodies against bovine viral diarrhea virus (BVDV): comparison between an experimental modified-live vaccine and three comercial inactivated vaccines

Ciência Rural, 2005
Os títulos e duração de anticorpos neutralizantes contra o vírus da Diarréia Viral Bovina (BVDV) induzidos por uma vacina experimental atenuada (vacina A: dose única) foram comparados com os induzidos por três vacinas comerciais inativadas (B, C e D ...
