title: Sodium dodecyl sulfate- and salt-extracted antigens from various Brucella species induce proliferation of bovine lymphocytes.
abstract: One- and two-dimensional gel electrophoresis and cellular immunoblotting were used to compare the protein profiles and immunogenic capabilities of salt- and sodium dodecyl sulfate-extracted components isolated from different Brucella species. Cellular immunoblotting demonstrated that freshly isolated bovine peripheral blood mononuclear cells proliferated to similar molecular mass components from the various Brucella extractions. One- and two-dimensional gel electrophoresis showed similarities in protein profiles among the different Brucella species that correlated with lymphocyte reactivity. The results presented in this study provide preliminary evidence that common proteins that induce lymphocyte proliferation are present among different Brucella species, suggesting that a genuswide subunit vaccine may be feasible.
