A patient with persistent diarrhea was found to have biopsy-proved colitis with large numbers of the protozoan Blastocystis hominis present in stool. Extensive evaluation failed to reveal any other potential etiologic agent of acute colitis. Following treatment with a course of metronidazole, the patient became asymptomatic, B hominis was no longer present in stool, and results of a repeated biopsy were normal. These observations are consistent with the role of B hominis as a gastrointestinal pathogen.
一名持续性腹泻患者经活检证实患有结肠炎，粪便中存在大量原生动物人芽囊原虫。全面评估未能发现急性结肠炎的任何其他潜在病因。经过一个疗程的甲硝唑治疗后，患者症状消失，粪便中不再有人芽囊原虫，重复活检结果正常。这些观察结果与人芽囊原虫作为胃肠道病原体的作用相符。
