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

Abstract 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.
