The replication and expression of bovine viral diarrhoea virus
2022The noncytopathic Australian bovine viral diarrhoea virus (BVDV) Trangie isolate was used to establish a one-step growth curve and to investigate previously uncharacterised aspects of pestivirus replication. The regions of the genome corresponding to the 5'UTR and the NS3 gene of BVDV were amplified by RT-PCR and then cloned and sequenced.

Prevalence of caftle infected with bovine viral diarrhoea virus in Switzerland
Veterinary Record, 2000A cross‐sectional study was made in a major cattle‐breeding area of Switzerland to investigate the prevalence and local distribution of animals antibody positive to bovine viral diarrhoea (BVD) virus and of persistently infected animals. The sample size and statistical analysis took into account the possible clustering of persistently infected animals ...

Bovine viral diarrhoea virus: biology, diagnosis and control
Veterinary Record, 2013BOVINE viral diarrhoea virus (BVDV) is an outstandingly successful virus. It is best known as the cause of a variety of clinical conditions resulting in economic losses in cattle, but understanding its biology has shown that BVDV and other pestiviruses have features unique among viruses.

Role of fomites and flies in the transmission of bovine viral diarrhoea virus
Veterinary Record, 1993The role played by contaminated hypodermic needles and nose tongs in the spread of bovine viral diarrhoea virus was investigated by using a persistently viraemic animal as a virus donor. Susceptible cattle were infected by using contaminated needles and tongs and in some instances they in turn infected animals kept with them. Non-biting flies which fed

CD4+ T-cell responses to bovine viral diarrhoea virus in cattle
Virus Research, 2000Friesian calves were infected with one of three isolates of bovine viral diarrhoea virus (BVDV) and used to establish parameters for an in vitro model of BVDV-reactive T-cell responses in cattle. The study assessed virus clearance, seroconversion, maturation of lymphoproliferative responses (both during and following disease resolution) and the antigen-

Assessing economic and social pressure for the control of bovine viral diarrhoea virus
Preventive Veterinary Medicine, 2005The objective of this paper is to present a preliminary assessment of variation in the economic impact of bovine viral diarrhoea virus (BVDV) at dairy farm level between a sample of nations within the EU and hence assess differences in pressure to respond to this disease that may be impeding progress in control and hence restricting collective benefits

Specific sequence amplification of bovine viral diarrhoea virus nucleic acid
Archives of Virology, 1990Bovine viral diarrhoea virus (BVDV) causes infection of cattle worldwide and is a common contaminant of cell cultures in the laboratory. Methods of diagnosis for BVDV are time-consuming and inconsistent. We describe the development of an in vitro test based on enzymatic DNA amplification with Thermus aquaticus DNA polymerase of sequences of BVDV cDNA ...

Bovine viral diarrhoea virus: its effects on ovarian function in the cow
Veterinary Microbiology, 2000Bovine viral diarrhoea virus (BVDV) is a major cattle pathogen responsible for a spectrum of symptoms, including reproductive failure. In this paper we investigate how BVDV interacts with the ovary. The viruses' tropism for the pre-ovulatory oocyte was studied by indirect immunohistochemistry.
