Аннотация
Classical swine fever (CSF) is endemic in Cuba and is one of the major health problems of the Cuban swine industry. The current efforts to control the disease in Cuba include vaccination with Porvac®, a subunit marker vaccine. Although the efficacy of Porvac against CSF virus (CSFV) subgenotype 1.4 has been extensively documented, little is known about the ability of the antibodies induced by this vaccine to neutralize other CSFV genotypes. In this study, sera collected from three pigs vaccinated with Porvac were able to efficiently neutralize CSFV strains belonging to genotypes 1, 2, and 3. The findings from this study indicate that additional in vivo studies are warranted to confirm the ability of this vaccine to protect pigs against CSFV genotypes 2 and 3.
