Immunoelectron microscopic comparisons of caliciviruses.

Abstract

Using immunoelectron microscopy, 9 serotypes of vesicular exanthema of swine virus (VESV) were compared with 5 serotypes of San Miguel sea lion virus and 7 additional calicivirus isolates from marine animals. In addition, swine caliciviruses and marine caliciviruses were compared with the vaccinal strain of feline calicivirus (FCV) F-9. Of 9 VESV types, 8 showed common antigenicity with San Miguel sea lion virus. Of 9 VESV types, 2 showed common antigenicity with FCV F-9. All 12 marine caliciviruses showed common antigenicity with VESV, but not with FCV F-9.
