چکیده
The aim of this review is to summarize the informations accumulated during the two last decades on hog cholera virus, a member of the pestivirus genus. Different aspects concerning the virus-host cell interactions, and the structural and antigenic properties of the virion itself are successively analyzed. Despite numerous works, many basic informations are still lacking, which can be explained by the difficulties inherent to the study of this virus.
