Abstract: To obtain LPS and its subunit O-PS with high purity from chicken S.boydii type 3, LPS from chicken Shigella was extracted with modified hot phenol-water method, high purified LPS was obtained through sephadex gel chromatography, O-PS was obtained by combination with acid hydrolysis method and sephadex gel chromatography. Biochemical assay showed that the purified LPS and O-PS with high purity, rabbit ideal loop experiment demanstrated that there was high activity in purified LPS.The result indicated that extracted LPS and O-PS could be used in specific pathogenesis research and developed as effective vaccine candidates.
