| Abstract: | Bovine viral diarrhea virus (BVDV) is one of the most important pathogenic viruses which mainly causes bovine viral diarrhea disease (BVD). BVDV can not only cause serious clinical symptoms, but also lead to decrease of immunity of livestock and infect other pathogens, resulting in significant increase of morbidity and mortality of sick animals, and causes significant losses to the cattle industry. With the development of molecular biology theory and technology in recent years, the research on BVDV has been deepening, and some new understandings have been made to the molecular biology of the virus. In this paper, the progress of molecular biology of BVDV in recent years is described from three aspects of the composition and function of virus, the epidemic situation of BVDV gene and the genetic and mutation of BVDV gene. |
