Abstract

Forty-three strains of Nocardia, one of Actinomadura and two of Nocardiopsis were studied using the comparative immunodiffusion technique. Three reference precipitation systems were employed: one represented Nocardia asteroides N10, one N. asteroides ATCC 19247, and one N. otitidis-caviarum ATCC 14629. One tight cluster was formed by the N. otitidis-caviarum strains and another tight cluster was formed by some of the N. asteroides strains studied. However, other strains of N. asteroides were distinct from the latter cluster. Furthermore, N. asteroides ATCC 19247, which is the type strain, differed from most ot the N. asteroides strains tested. Strains of the species N. asteroides, N. brasiliensis, N. farcinica and N. otitidis-caviarum were found to be closely related, while N. amarae strains differed slightly from this group. The strains referred to Actinomadura and Nocardiopsis were clearly distinct from the three Nocardia reference strains; nevertheless, three antigens common to these genera were revealed.

摘要

采用免疫扩散技术对43株诺卡氏菌、1株马杜拉放线菌和2株拟诺卡氏菌进行了研究。使用了三种参考沉淀系统：一种代表星形诺卡氏菌N10，一种代表星形诺卡氏菌ATCC 19247，一种代表耳氏诺卡氏菌ATCC 14629。耳氏诺卡氏菌菌株形成了一个紧密的簇，所研究的一些星形诺卡氏菌菌株形成了另一个紧密的簇。然而，其他星形诺卡氏菌菌株与后一个簇不同。此外，作为模式菌株的星形诺卡氏菌ATCC 19247与大多数测试的星形诺卡氏菌菌株不同。发现星形诺卡氏菌、巴西诺卡氏菌、豚鼠耳炎诺卡氏菌和耳氏诺卡氏菌的菌株密切相关，而阿马拉诺卡氏菌菌株与该组略有不同。所提及的马杜拉放线菌和拟诺卡氏菌菌株与三种诺卡氏菌参考菌株明显不同；然而，揭示了这些属共有的三种抗原。
