Schistosoma mansoni eggs were isolated and staged microscopically according to size. The eggs were then allowed to hatch and were reexamined; the hatching percentage of mature eggs was calculated. The results show clearly that not only do immature eggs not hatch, but also mature eggs greater than 160 microns fail to hatch.
曼氏血吸虫卵被分离出来，并根据大小在显微镜下进行分期。然后让这些卵孵化并再次检查；计算成熟卵的孵化率。结果清楚地表明，不仅未成熟的卵不孵化，而且大于160微米的成熟卵也不能孵化。
