    • 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.
    • PCT No.PCT / JP95 / 01125 Sec。 371日期1996年12月2日第 102(e)日期1996年12月2日PCT提交1995年6月7日PCT公布。 公开号WO95 / 34322 日期1995年12月21日本发明旨在提供一种制备皮肤坏死毒素的方法,由博德特利氏菌产生的改良的皮肤坏死毒素类毒素,以及由博德特氏菌产生的所述改良的皮肤坏死毒素类毒素和由巴斯德氏菌产生的皮肤坏死毒素类毒素的类毒素混合物 。 提供了部分纯化皮肤坏死毒素的方法,其包括将含有皮肤坏死毒素的溶液与通过直接硫酸化硫酸化的色谱凝胶接触,或者将硫酸化分子共价键合到色谱凝胶上,从而使皮肤坏死毒素吸附在 凝胶,并从凝胶中洗脱吸附的皮肤坏死毒素。 还提供了由博德特氏菌产生的皮肤坏死毒素获得的类毒素,所述皮肤坏死毒素通过上述部分纯化皮肤坏死毒素的方法制备,以及通过混合所述类毒素和由产毒巴斯德氏菌产生的皮肤坏死毒素类毒素制备的类毒素混合物, 类毒素混合物对于预防猪萎缩性鼻炎是安全有效的。
