Two apparently healthy children from the same family were found to have moderate to heavy Blastocystis hominis in their stool samples whilst being investigated for intestinal symptoms: sporadic, painless, rectal bleeding in one and persistent diarrhoea in the other. After treatment with metronidazole, they had no further signs, and stool samples became negative. Eighteen months later, both were asymptomatic, and stool samples continued to be negative for the parasite.
在对两名来自同一家庭的、表面健康的儿童进行肠道症状调查时，发现他们的粪便样本中存在中度至重度的人芽囊原虫：其中一名儿童有散发性、无痛性直肠出血症状，另一名则持续腹泻。在接受甲硝唑治疗后，他们不再有任何症状，粪便样本也转为阴性。18个月后，两人均无症状，粪便样本中该寄生虫检测仍为阴性。
