title: A single dose immunization with rabbit haemorrhagic disease virus major capsid protein produced in Saccharomyces cerevisiae induces protection.
abstract: The gene coding for the major capsid protein (VP60) from rabbit haemorrhagic disease virus was expressed in Saccharomyces cerevisiae under the phosphoglycerate kinase promoter. The recombinant VP60 produced in yeast was antigenically similar to the viral polypeptide as determined with a polyclonal serum. Electron microscopic observation of the recombinant yeast-derived antigen revealed the presence of virus-like particles similar in size and appearance to native capsids. Subcutaneous vaccination of rabbits with a single dose of this antigen in the absence of commercial adjuvants conferred complete protection against the haemorrhagic disease.
