摘要
对分离自陕西渭南的２４ 株鸽源多杀性巴氏杆菌，用Ｃａｒｔｅｒ 荚膜群鉴定法和Ｈｅｄｄｌｅｓｔｏｎ 热稳定抗原鉴定法进行血清学分型研究。结果表明，在鉴定的２４ 株多杀性巴氏杆菌中，除３ 株未能分群外，其余２１ 株均为荚膜Ａ 群。共鉴定出标准血清型菌株１９ 株，主要血清型为Ａ：１ 型１７ 株；其次为Ａ：１（２） 型和Ａ：１（１４） 型各１ 株。５ 株未能定出血清型。在Ａ：１ 型菌株中，１２ 株与标准血清反应产生一条沉淀线，１ 株产生４ 条沉淀线，其余菌株可形成２ 条沉淀线，说明在部分Ａ：１ 型菌株中存在２ 种以上的抗原成分。
Twenty four isolates of pasteurella multocida were recovered from dead pigeons in Shaanxi Weinan.The isolates were tested with Carter′s capsule assay and Heddleston′s thermal stability antibody assay.The results showed that, the groups of Capsules on these bacteria were A(21) besides 3 strains. 19 strains of standard serological type have been assayed besides 5 strains. The serological type were:17 strains were type A:1(70.8%), 1 strain was type A:1(2)(4.2%) and 1 strain was type A:1(14) (4.2%) .The reaction between 12 strains of type A:1 with standard serum produced one precipitin line, 1 strain produced four precioitin lines and others producted two precipitin lines. A few strains had obvious cross-reaction. It is indication that more than two kinds of antigen components exist in some A:1 bacterium isolates.
