Abstract
Immunoelectrophoresis and its modifications were applied to analysis of a lipopolysaccharide-like component (LPS-LC) extracted from Borrelia garinii strains K24 and K48 isolated from Ixodes ricinus and Borrelia burgdorferi sensu stricto strain B31. A modification of the hot phenol-water method was used for isolation of LPS. Immunoelectrophoresis (IE) and crossed immunoelectrophoresis (CIE) of LPS-LC with polyclonal rabbit antisera revealed a pattern and properties partially similar to LPS from other Gram-negative bacteria. B. garinii LPS-LC formed in CIE a diffuse band extending from the start to the anode. Similarly, the shape and position of the band in IE did not show major differences from LPS of other Gram-negative bacteria. The LPS-LC extracted from the three genomic groups of B. burgdorferi sensu lato were found to have similar immunochemical properties irrespective of their genotype origin.
