Twenty-two monoclonal antibodies (mAbs) specific for smooth lipopolysaccharide (S-LPS) were generated by fusion of spleen cells from mice infected with the rough Brucella melitensis strain B115 with the NSO myeloma. According to reactivity in enzyme-linked immunosorbent assay (ELISA) with O-polysaccharide (O-PS) and absence of reactivity with rough lipopolysaccharide (R-LPS), it was postulated that these mAbs recognized epitopes present on the O-PS. Most of the mAbs reacted equally well in ELISA and immunoblotting with S-LPS types of Brucella A and M dominant strains and were designated as specific for common (C) epitopes. Three mAbs were highly specific for M dominant S-LPS. All these mAbs, in contrast to a mAb specific for the A epitope, showed little or no cross-reactivity with Yersinia enterocolitica O:9 S-LPS. S-LPS of B. melitensis B115 was extracted and analysed by immunoblotting and ELISA with mAbs specific for A, M and C epitopes. Reactivity of the mAbs with this S-LPS was compared to reactivity with S-LPS of A and M dominant smooth Brucella strains. The results suggest that S-LPS of B. melitensis B115 bears mainly C epitopes and a few M epitopes. The very weak reactivity of this S-LPS with the mAb specific for the A epitope and the fact that the mAbs specific for C and M epitopes showed little or no cross-reactivity with Y. enterocolitica O:9 S-LPS suggest that O-PS from this rough strain could be used to distinguish Y. enterocolitica O:9 infection from Brucella infection.(ABSTRACT TRUNCATED AT 250 WORDS)
