应用间接电子免疫细胞化学标记法,在纯细菌培养的超薄切片和幼年牙周炎牙菌斑中标记放线菌伴生放线杆菌(b型)。用2.5%的戊二醛固定,包埋在甲基丙烯酸乙二醇酯中,用高度稀释的兔抗放线菌γ球蛋白标记,再与稀释羊抗兔γ球蛋白与辣根过氧化物酶偶联孵育,可获得最佳标记。以及随后的过氧化物酶的组织化学可视化。这些标记条件被用来确定与常见的菌斑细菌不存在交叉反应。在5个标记的斑块标本中,有2个标本对这种伴放线放线菌的血清型呈阳性。在一个标本中,大量标记的细菌只位于斑块层的最顶端。在另一个标本中,标记的细胞散布在斑块的各处。用正常兔γ球蛋白进行的对照实验均为阴性。
The use of an indirect electron immunocytochemical labelling procedure for labelling Actinobacillus actinomy cetemcomitans (serotype b) in ultrathin sections of pure bacterial cultures and in localized juvenile periodontitis‐derived plaque is described. Optimal labelling was obtained after fixation with 2.5% glutaraldehyde, embedding in glycol methacrylate and labelling with highly diluted absorbed rabbit anti‐A. actinomycetemcomtians γ‐globulin followed by incubation with diluted goat anti‐rabbit γ‐globulin conjugated with horseradish peroxidase. and subsequent histochemical visualization of the peroxidase. These labelling conditions were used to determine that no cross reactions existed with commonly found plaque bacteria. Two of 5 labelled plaque specimens were positive for this A. actinamycetemcomitans serotype. In one specimen large numbers of labelled bacteria were located only in the most apical portion of the plaque layer. In another specimen labelled cells were scattered throughout the plaque. Control experiments using normal rabbit γ‐globulin were all negative.
