Immunology of chronic BVDV infections
Biologicals, 2013Bovine viral diarrhea virus can maintain prolonged infections within immunoprivileged sites after an otherwise transient infection of a cow, calf, or bull. Various sites provide unique niches for viral replication which are not susceptible to the complete surveillance commonly provided by the bovine immune system.

BVDV infection risk in the course of the voluntary BVDV eradication program in Styria/Austria
Preventive Veterinary Medicine, 2005A total of 1362 persistently BVDV-infected animals were identified in 850 herds during the first 3 years of the voluntary BVDV eradication program in Styria/Austria. Within the same period of time, the prevalence of BVDV-infected herds dropped from 7.3% to 2.2% of the 4412 herds covered by the program.

The extended genetic diversity of BVDV-1: Typing of BVDV isolates from France
Veterinary Research Communications, 2007Keywords BVDV.Bovineviraldiarrhoeavirus.RT-PCR.Sequencing.TypingBovine viral diarrhoea virus (BVDV) type 1 and type 2 belong to the genus Pestivirus,family Flaviviridae. BVDV-1 is a causative agent of bovine viral diarrhoea and mucosaldisease. Highly virulent BVDV-2 isolates may cause haemorhagic syndrome with highmortality of cattle.

SIR, — Bovine viral diarrhoea virus (bvdv) was first reported in a British alpaca herd in 2005, in a seven-month-old animal with illthrift, recurrent diarrhoea and joint swelling ([Foster and others 2005][1]).

The impact of BVDV infection on adaptive immunity
Biologicals, 2013Bovine viral diarrhea virus (BVDV) causes immunosuppression of the adaptive immune response. The level of suppression of the adaptive immune response is strain dependent. The early events of antigen presentation require activation of toll-like receptors that results in the release of pro-inflammatory cytokines.

Eradication of BVDV in cattle: the Norwegian project
Veterinary Record, 2013The intention of this collaborative project was eradication of pestivirus from the Norwegian cattle population of about 30,000 dairy and beef herds, primarily by identification and culling of persistently infected (PI) animals. Testing was performed in four tiers, with examination for pestivirus antibodies by indirect ELISA in (1) bulk milk, (2) pooled

Biologicals, 2013
Providing acquired immune protection against infection with bovine viral diarrhea viruses (BVDV) is challenging due to the heterogeneity that exists among BVDV strains and the ability of the virus to infect the fetus and establish persistent infections. Both modified live and killed vaccines have been shown to be efficacious under controlled conditions.

Acridine derivatives as anti-BVDV agents
Antiviral Research, 2011Twenty-six 9-aminoacridine derivatives were evaluated in cell-based assays for cytotoxicity and antiviral activity against a panel of 10 RNA and DNA viruses. While seven compounds (9, 10, 14, 19, 21, 22, 24) did not affect any virus and two (6, 11) were moderately active against CVB-5 or Reo-1, 17 compounds exhibited a marked specific activity against ...

A bovine viral diarrhea/mucosal disease (BVD/MD) control and eradication program was introduced in Lower Austria in 1996, according to the Swedish model. At present 9800 out of 17,000 herds are part of this program. An important risk factor for BVDV-transmission under local conditions is communal grazing.

American Association of Bovine Practitioners Conference Proceedings, 1994
Much progress had been made in defining BVDV in molecular terms. While this information has been useful in some aspects of BVDV pathogenesis, this information has not led to a significant decrease in concern expressed by practitioners regarding prevention and control of BVDV-induced disease.
