title: Reduction of Brucella species and Francisella tularensis cross-reacting agglutinins by dithiothreitol.
abstract: Cross-reaction agglutinin titers to Brucella abortus antigen were found in 42 of 128 tularemia serum specimens, and cross-reaction titers to Francisella tularensis antigen were found in 8 of 34 brucellosis serum specimens. The cross-reaction titers were reduced to 10 or less by dithiothreitol, suggesting that the titers are due to immunoglobulin M antibody.
