The lymph draining the prefemoral lymph node of a sheep infected with Trypanosoma congolense was examined over a period of 10 days. Only six trypanosomes were detected in 1500 ml of this fluid during this time, in spite of the animal having about 65,000 organisms/ml in its blood. It is concluded that the suggestion that T congolense is a strict plasma parasite is essentially proven for this specific situation.
在10天的时间里，对感染刚果锥虫的绵羊的股前淋巴结引流的淋巴液进行了检查。在此期间，在1500毫升这种液体中仅检测到6条锥虫，尽管该动物血液中的锥虫数量约为每毫升65000个。结论是，关于刚果锥虫是一种严格的血浆寄生虫的说法在这种特定情况下基本得到了证实。
