Pseudotypes of vesicular stomatitis virus with the mixed coat of reticuloendotheliosis virus and vesicular stomatitis virus.

Vesicular stomatitis virus (VSV) forms pseudotypes with envelope components of reticuloendotheliosis virus (REV). The VSV pseudotype possesses the limited host range and antigenic properties of REV. Approximately 70% of the VSV, Indiana serotype, and 45% of VSV, New Jersey serotype, produced from the REV strain T-transformed chicken bone marrow cells contain mixed envelope components of both VSV and REV. VSV pseudotypes with mixed envelope antigens can be neutralized with excess amounts of either anti-VSV antiserum or anti-REV antiserum.
