Abstract: Two monoclonal antibodies (MAbs) against the lipopolysaccharides (LPSs) of Coxiella burnetii (C.b.) strains Priscilla and Nine Mile were prepared characterized by their interaction with synthetic glycoconjugates representing parts of LPSs of C.b. in virulent phase. Both MAbs were directed against immunodominant epitopes comprising core constituent of LPSs, Kdo (3-deoxy-α-D-manno-2-octulopyranosylonic acid). ELISA showed that the anti-Nine Mile MAb 4/11 bound preferably to disaccharides (α-Kdo (2 → 4) α-Kdo and α-Kdo (2→4) α-(5d) Kdo), while the anti-Priscilla MAb 1/4/H bound to all conjugates, though with various intensity. On the other hand, immunoelectron microscopy revealed a positive binding of only one glycoconjugate, namely the trisaccharide α-Kdo (2→4) α-Kdo (2→4) α-Kdo-BSA, to both MAbs. In competitive ELISA (cELISA), the anti-Priscilla MAb 1/4/H distinguished the strains Nine Mile and Priscilla, while the anti Nine Mile MAb 4/11 did not.
