Abstract:

The most frequently-reported Bovine viral diarrhea virus(BVDV) subgenotype was 1b, followed by 1a and 2a. 1t and 1n were the less reported subgenotypes, and 1v was a new popular subgenotype in recent years. Recently, the emergence of many new BVDV subgenotypes showed that continuous genetic variation made its prevention and control more and more difficult. The large number of various BVDV subgenotypes had been documented in European countries, indicating greater genetic diversity of BVDV in this continent. The number of BVDV strains found in Asia was significantly higher than those in other continents, and 1b was the most prevalent subgenotype in Asia. BVDV-3 had been reported most frequently in Europe and had also been reported in Asia. This study reviewed the worldwide prevalence of BVDV, enriched the molecular epidemiological data of BVDV, and provided a theoretical basis for the prevention and control of BVDV.

Key words: Bovine viral diarrhea virus, subgenotype, prevalence, genetic diversity
