Abstract
  1. Rats, when fed the soluble specific substance of Types I, II and III pneumococcus, excrete a very large proportion in the feces. 2. Following ingestion of these substances, tests sensitive enough to detect 1 part in 2,000,000 of serum, and 1 part in 3,000,000 of urine, were negative. 3. The polysaccharide of Type I, when recovered from the feces, is as active an immunizing agent as it was originally.
摘要
  1. 给老鼠喂食 I、II 和 III 型肺炎球菌的可溶性特异性物质时,很大一部分会从粪便中排出。

  2. 这些物质被摄入后,检测血清中 1/2000000 和尿液中 1/3000000 的敏感度足以呈阴性。

  3. 从粪便中回收的 I 型多糖,其免疫原性与最初一样强。
