一株有争议的志贺氏菌的抗原分析与血清型检定

对中国医学细菌保藏管理中心所存，1935年国外分离，国内检定结果不一的一株志贺氏菌51331进行了详细的抗原分析，确定为福氏志贺氏菌X变种。 该菌能与国内外出品的福氏3型特异血清发生交叉凝集的原因，主要是由于上述诊断用血清中交叉反应性抗体尚未吸收纯净，至少没用类似51331这样的菌株参与成品血清检定的缘故。因此，建议在生产福氏3型特异血清时，应用本菌种参与检定以提高制品质量。本菌种作为诊断血清检定时用的菌种是十分有价值的。

Antigenic analysis and identification of serotype for an arguable strain of Shigella]

A strain of Shigella, 51331, was isolated abroad in 1935, and stored in The Center for Medical Culture Collection, Beijing. Since the serotype of this strain was arguable in China. It was identified as Sh. flexneri var. X with antigenic analysis. As agglutinin absorption technic was used in preparing diagnostic factor serum, it appears that the culture of strain 51331 could be agglutinated by Shigella antiserum flexner type 3 (Sh. flexneri) made in China and England. The present author suggested that diagnostic serum for type 3 or Sh. flexneri should be checked up with the strain 51331 for type factor specific. Strain 51331 is, therefore, useful for purpose of identification when preparing diagnostic serum for Shigella.
