The smooth lipopolysaccharide (sLPS)-protein complex of Brucella abortus has been identified as the immuno-dominant component, which reacts with antibody in the serological tests generally used for diagnosis of brucellosis (1). B. abortus sLPS carries the major A (abortus) antigen, the species-specific epitope located within, and the minor M (melitensis) determinant, which cross reacts with B. melitensis antigen. O-chain prepared fromB. abortus LPS was reported to have protective antigen properties in mice (2). Unlike the LPS of other enterobacteriaceae, sLPS separates primarily into the phenol phase when B. abortus cells are extracted with hot phenol-water by the Westphal method (3–7). The crude fraction of sLPS, which was used to study the properties of smooth B. abortus in the early eighties, is associated with various proteins ranging from 10–30% of the weight composition, most of which are non-covalently bound (3). These non-covalently linked proteins or nucleic acids can be removed by treatment with chaotropic agents and by gel filtration in the presence of chaotropic agents and detergents.
