Antigenic relationships of lymphocytic choriomeningitis virus and Tacaribe virus in the indirect haemagglutination test.

The indirect haemagglutination test has been developed for use with LCM and Tacaribe viruses employing antibody-sensitized erythrocytes. Both in this test and in the indirect haemagglutination inhibition test cross-reactions between LCM and Tacaribe viruses were revealed. This opens new perspectives for group and species identification of arenaviruses.
