    摘要: A variant of Erysipelothrix rhusiopathiae surface protective antigen SpaA protein or of a shortened form of SpaA (ΔSpaA) in which a portion of SpaA protein is deleted for protection from Erysipelothrix rhusiopathiae infection and a process for preparing the same are provided. Introduction of amino acid substitution at a specific site in the amino acid sequence of SpaA or ΔSpaA protein provides a variant of SpaA or ΔSpaA protein which is immunogenic and is expressed in E. coli as inclusion bodies. The variant of SpaA or ΔSpaA protein of the present invention may easily be recovered and purified since it is expressed in E. coli as inclusion bodies.

    摘要: The present invention aims at providing a method for preparing dermonecrotic toxin, an improved toxoid of dermonecrotic toxin produced by Bordetelia and a toxoid mixture comprising said improved toxoid of dermonecrotic toxin produced by Bordetella and a toxoid of dermonecrotic toxin produced by Pasteurella. There is provided a method for partially purifying dermonecrotic toxin which comprises bringing a dermonecrotic toxin-containing solution into contact with a chromatographic gel sulfated by direct sulfation or a chromatographic gel to which a sulfated molecule is covalently bonded to thereby make the dermonecrotic toxin adsorbed on the gel, and eluting the adsorbed dermonecrotic toxin from the gel. There is also provided a toxoid obtained from dermonecrotic toxin produced by Bordetella, said dermonecrotic toxin being prepared by the above method for partially purifying dermonecrotic toxin, and a toxoid mixture prepared by mixing said toxoid and a toxoid of dermonecrotic toxin produced by toxigenic Pasteurella, said toxoid mixture being safe and effective for preventing the atrophic rhinitis in pigs.
