Bovine viral diarrhea (BVD), bovine viral diarrhoea (UK English) or mucosal disease, previously referred to as bovine virus diarrhea (BVD), is an economically significant disease of cattle that is found in the majority of countries throughout the world. [1] .

Bovine Viral Diarrhea (BVD) is a disease of cattle caused by the Bovine Viral Diarrhea Virus (BVDV). The virus is widespread, and most herds are at risk for infection. In the susceptible herd, BVD can be a serious, costly disease. The signs of BVD vary, depending on the immune status of the exposed animals, and the strain of the infecting virus.

Control of bovine viral diarrhea virus (BVDV) in cattle populations across most of the world has remained elusive in spite of advances in knowledge about this viral pathogen. A central feature of virus perseverance in cattle herds is the unique ...

2021年5月14日 · BVDV is one of the most important viruses affecting bovine species throughout the world (1–4). It is a complex cocktail of two strains of the virus inducing various clinical syndromes of the affected animals . BVDV was first identified in the USA in a herd of cattle that suffered from acute gastroenteritis with high mortality rates .

Bovine viral diarrhea virus (BVDV) is the causative agent of bovine viral diarrhea (BVD), which results in significant economic losses in the global cattle industry. Fortunately, various diagnostic methods available for BVDV have been established.

Over the past 40 years, "bovine viral diarrhea virus" or BVDV became responsible for major economic losses to the bovine industry. Currently, BVDV is classified in the Flaviviridae family, Pestivirus genus which now has 11 species including BVDV (Pestivirus, A, B, H), border disease virus (Pestivirus D), and classical swine fever virus ...

牛病毒性腹泻病毒 (bovine viral diarrhea virus, BVDV)主要感染牛，孕期母畜感染BVDV可引起新生动物持续性感染 (persistent infection, PI)，产生免疫耐受 [1]。 PI动物血清抗体呈阴性但终身向外排毒，是BVDV最重要的传染源。 BVDV是单股正链RNA病毒，属于黄病毒科、瘟病毒属。 根据BVDV基因遗传多样性以及抗原差异分析可将其分三大类，即BVDV-1、BVDV-2和BVDV-3 (HoBi-like virus) [2 - 3]。

Bovine viral diarrhea virus (BVDV) is a small, enveloped virus with a single-stranded, positive-sense RNA genome belonging to the genus Pestivirus in the Flaviviridae family. BVDV is the etiological agent of serious diseases in cattle and other ruminants [1,2,3]. Infection by BVDV induces a range of clinical manifestations including respiratory ...

Bovine Virus Diarrhoea Virus (BVDV) is a viral disease of cattle that causes reproductive losses and a range of other disease syndromes in cattle. The costs of reproductive failure and production losses can be very high and many countries have introduced eradication schemes for the virus with varying success.

探究内蒙古自治区通辽市牛病毒性腹泻病毒 (BVDV)感染毒株主要基因型,为BVDV流行病学及防控提供参考依据。 试验前期在内蒙古通辽市某牛场采集腹泻犊牛粪便样品经PCR检测,将BVDV阳性的粪便样品处理后接种到牛肾细胞 (MDBK)中进行分离,通过RT-PCR、间接免疫荧光染色对分离株进行鉴定,并对其基因组全长进行测序,根据 5'UTR 、 Npro 和 E2 基因序列进行遗传进化分析和基因分型鉴定。 结果表明,试验成功分离到一株BVDV毒株,将其命名为NM-21,接种NM-21的MDBK未 …
