Bovine viral diarrhea virus (BVDV) in cell lines used for somatic cell cloning

Theriogenology, 2005
Culture of cell lines from fetuses or postnatal animals is an essential part of somatic cell cloning. Fetal bovine serum (FBS) is commonly used in media for propagation of these cells. Unfortunately, bovine fetuses and postnatal animals as well as FBS are all possible sources of non-cytopathic bovine viral diarrhea virus (BVDV) which is widely ...

Polymethylated γ-Carbolines with Potent Anti-Bovine Viral Diarrhea Virus (BVDV) Activity

HETEROCYCLES, 2009
Several anti-BVDV agents with a polymethylated γ-carboline skeleton were synthesized, and their anti-BVDV activity was evaluated. The most potent antiviral agent, SK3M4M5M (20), was synthesized by Pd-catalyzed Buchwald-Hartwig amination reaction followed by annulation reaction as key steps. The structure-activity relationship was analyzed.

Electron Microscopic study of two strains of bovine viral diarrhea virus (BVDV)

Proceedings, annual meeting, Electron Microscopy Society of America, 1989
Bovine viral diarrhea virus (BVDV) is an economically important pathogen of cattle throughout the world, causing a wide range of clinical syndromes. Virion is spherical, 40-70 nm in diameter, with an envelope tightly applied to a spherical nucleocapsid 25-35 nm in diameter with icosahedral symmetry (figure 1 and 2) (Matthews, 1979) .

Detection of bovine viral diarrhea virus (BVDV) in single or small groups of preimplantation bovine embryos

Theriogenology, 2007
The objectives of this study were to develop techniques to detect BVDV associated with single or small groups of bovine embryos contained in small aliquots of medium using either virus isolation (VI) or real time quantitative polymerase chain reaction (RT-QPCR) assays.

Prolonged Persistence of Cytopathogenic Bovine Viral Diarrhea Virus (BVDV) in a Persistently Viremic Cattle

Journal of Veterinary Medicine, Series B, 1993
SummaryA bull persistently viremic with noncytopathogenic (ncp) BVDV was inoculated with the cytopathic (cp) BVDV strain TGAC, which had been found to be antigenically different from the endogenous ncpBVDV (ncpW8). Neutralizing antibodies against strains NADL and TGAC were detectablc 12 days and four weeks post infection, respectively.

Immunohistochemical diagnosis of persistent infection with Bovine Viral Diarrhea Virus (BVDV) on skin biopsies

Schweizer Archiv für Tierheilkunde, 2007
Detection of persistent infection with BovineViral Diarrhea Virus (BVDV) is essential for both epidemiological and clinical reasons. In addition to the classical virological methods such as virus isolation in tissue culture, ELISA and RT-PCR, immunohistochemistry of skin biopsies has become a useful and reliable tool. Assuming that the presence of BVDV

Alteration in ultrastructural morphology of bovine embryos following subzonal microinjection of bovine viral diarrhea virus (BVDV)

Zygote, 2008
SummaryThe aim of the present study was to evaluate the development and ultrastructure of preimplantation bovine embryos that were exposed to bovine viral diarrhea virus (BVDV) in vitro.The embryos were recovered from superovulated and fertilized Holstein-Friesian donor cows on day 6 of the estrous cycle.

What is Known About the Antiviral Agents Active Against Bovine Viral Diarrhea Virus (BVDV)?

Current Medicinal Chemistry, 2010
Viruses belonging to the Flaviviridae family cause clinically significant diseases in humans and animals. This family includes three genera: Pestivirus [including bovine viral diarrhea virus (BVDV)], Flavivirus [including yellow fever virus (YFV), dengue virus, and West Nile virus (WNV)], and Hepacivirus [including hepatitis C virus (HCV)].

Characteristics in the epidemiology of bovine viral diarrhea virus (BVDV) of relevance to control

Preventive Veterinary Medicine, 2005
An understanding of the driving forces of BVDV transmission can be gained by considering the reproductive rate, between individuals and between herds. The former determines the prospects for eliminating the infection from herds, and the latter is the key to persistence at the population level.

Viral quantification of bovine viral diarrhea virus (BVDV) with Real Time PCR

2006
BVDV is responsible of persistent infection (PI) in cattle. PI animals can develop a severe pathology, the Mucous Disease (MD). The aim of this work was to develop a Real Time PCR (qRT-PCR) in order to quantify the virus amount in different organs and apparatus from PI and MD affected animals.
