Genotype 1 and genotype 2 bovine noroviruses are antigenically distinct but share a cross-reactive epitope with human noroviruses.

ABSTRACT: The bovine enteric caliciviruses Bo/Jena/1980/DE and Bo/Newbury2/1976/UK represent two distinct genotypes within a new genogroup, genogroup III, in the genus Norovirus of the family Caliciviridae. In the present study, the antigenic relatedness of these two genotypes was determined for the first time to enable the development of tests to detect and differentiate between both genotypes. Two approaches were used. First, cross-reactivity was examined by enzyme-linked immunosorbent assay (ELISA) using recombinant virus-like particles (VLPs) and convalescent-phase sera from calves infected with either Jena (genotype 1) or Newbury2 (genotype 2). Second, cross-reactivity was examined between the two genotypes with a monoclonal antibody, CM39, derived using Jena VLPs. The two genotypes, Jena and N
