The evolution of bovine viral diarrhea: a review
AUTOR(ES)
Goens, Denise
RESUMO
The economic importance of bovine viral diarrhea is increasing with the emergence of seemingly more virulent viruses, as evidenced by outbreaks of hemorrhagic syndrome and severe acute bovine viral diarrhea beginning in the 1980s and 1990s. It appears that evolutionary changes in bovine viral diarrhea virus were responsible for these outbreaks. The genetic properties of the classical bovine viral diarrhea virus that contribute to the basis of current diagnostic tests, vaccines, and our understanding of pathogenic mechanisms are now being reevaluated because of these “new” virus strains. This shift in virulence has confounded both nomenclature and the significance of current bovine viral diarrhea virus categorization.
