    • A substituted Norovirus capsid protein monomer, having only the P-domain and called an antigen-Norovirus P-domain monomer, includes a foreign antigen inserted into one or more of three surface loops present on each P-domain monomer by molecular cloning. The antigen-P-domain monomer can assemble spontaneously into an octahedral form, called an antigen-Norovirus P-particle, that is composed of 24 copies of the antigen-P-domain monomer. Each substituted P-domain monomer will contain one to three copies of the foreign antigen, for a total of 24-72 antigen copies on each antigen-P-particle. The antigen-P-particle is useful in methods for diagnosing, immunizing and treating individuals infected with a foreign virus, for example Rotavirus, and can serve as a carrier for presentation of foreign antigens for development of novel vaccines against many infectious and non-infectious diseases. The substituted Norovirus P-particles can be readily produced in E. coli and yeast, are highly stable and tolerate a wide range of physio-chemical conditions. A modified Norovirus P-domain monomer includes one or more restriction recognition sites inserted within one or more of the three loops of the P-domain monomers, to provide user-friendly cloning cassettes for conveniently inserting candidate foreign antigens into the surface loops. The P-particle-VP8 chimeras may also serve as a dual vaccine against both rotavirus and norovirus.

    • A method for detecting a Norwalk-Like Virus (NLV) in a biological sample, comprising the steps of: obtaining a biological sample suspected of containing a NLV; contacting the biological sample with at least one human histo-blood group antigen to allow formation of a complex of the NLV with the antigen; and detecting the antigen NLV complex. The antigen-NLV complex can be detected by contacting the NLV-antigen complex with a NLV antibody that binds at an epitope of the NLV, and detecting the NLV antibody. The invention also includes a method for identifying compounds, and the compounds, that can inhibit the binding between a Norwalk-Like Virus (NLV) and a histo-blood group antigen. The method includes the steps of contacting the NLV target with a compound; subsequently contacting the NLV with a standard compound that is known to be bound at a determinant binding site of the NLV; and determining whether the binding of the standard compound is decreased in the presence of the test compound, the decrease in binding being an indication that the test compound inhibits the binding activity of the NLV with the standard compound. In preferred embodiments, the standard compound is a histo-blood group antigen.
