The results of identification of the agent ("Progress" strain) isolated from the organs of a calf sacrificed in the early stage of pneumonia are presented. The agent adapted to yolk sacs of chick embryos was pathogenic for white mice by the intracerebral route and for monkeys infected with aerosol. The infected animals developed specific complement-fixing antibody. The antigen of the agent reacted in the CFT with homologous immune sera and with sera against ornithosis and other members of the ornithosis-lymphogranuloma-trachoma (OLT) group. In cell cultures the agent multiplied well and produced cytoplasmic inclusion bodies characteristic of the OLT group members.
本文展示了从一头在肺炎早期被宰杀的小牛器官中分离出的病原体（“进展”株）的鉴定结果。适应鸡胚卵黄囊的病原体通过脑内途径对小白鼠致病，通过气溶胶感染对猴子致病。受感染的动物产生了特异性补体结合抗体。该病原体的抗原在补体结合试验中与同源免疫血清以及抗鸟疫和鸟疫-淋巴肉芽肿-沙眼（OLT）组其他成员的血清发生反应。在细胞培养中，该病原体繁殖良好，并产生了OLT组成员特有的细胞质包涵体。
