Immunoglobulin specificity of the microagglutination test for the Legionnaires' disease bacterium

Ann Intern Med. 1979 Apr;90(4):690. doi: 10.7326/0003-4819-90-4-690.


Differences in results of microagglutination tests for the Legionnaires' disease bacterium on untreated sera and sera treated with 2-mercaptoethanol suggest that, like other agglutination tests, the microagglutination test is heavily dependent on the presence of IgM antibody.
