Trypanosomes were separated on DEAE cellulose columns from blood samples taken during the first parasitemic wave in T. vivax or T. congolense infected cattle. The mean volume of T. vivax organisms in five steers increased from 16.3 fl SE 0.7 on day five to 20.7 fl SE 0.7 on day eight. Assuming an even distribution of T. vivax throughout the vasculature, the total trypanosome volume at peak parasitemia (36.400 trypanosomes per microliter on day six) was calculated to be about 0.067% of the blood volume, i.e. 8.0 ml. The mean volume of the separated T. congolense organisms was 14.0 fl SE 0.3 on day nine post infection (mean parasitemia of 3.100 trypanosomes per microliter blood). The T. congolense organisms in the jugular venous blood accounted for about 0.0043% of the jugular venous blood volume.
从感染了活泼锥虫或刚果锥虫的牛在第一次虫血症高峰期采集的血样中，通过DEAE纤维素柱分离出锥虫。5头公牛体内活泼锥虫的平均体积从第5天的16.3飞升（标准误0.7）增加到第8天的20.7飞升（标准误0.7）。假设活泼锥虫在整个脉管系统中均匀分布，在虫血症高峰期（第6天每微升血液中有36400个锥虫），锥虫总体积计算约为血容量的0.067%，即8.0毫升。感染后第9天，分离出的刚果锥虫的平均体积为14.0飞升（标准误0.3）（每微升血液中平均虫血症为3100个锥虫）。颈静脉血中的刚果锥虫约占颈静脉血容量的0.0043%。
