Chagas disease is a serious problem of parasitic disease in the American continent, this zoonosis is caused by the flagellated protozoan known as Trypanosoma cruzi and transmitted through trypomastigotes present in the blood of sick hosts or in the faeces of the triatomines.

Metacyclic trypomastigotes were detected in the faeca material of Triatoma pallidepennis maintained in the laboratory after the xenodiagnosis study performed on a patient with suspected Chagas disease, which allowed to administer treatment in a timely manner in the acute phase of this disease.

南美锥虫病是在美洲大陆上的一个严重的寄生虫病问题，这种人畜共患病是由有鞭毛的原生动物，即克鲁斯锥虫引起的，并通过患病宿主血液或三atomines粪便中存在的锥虫病传播。

在对疑似恰加斯病的患者进行异种诊断研究后，在实验室中保存的苍白Triatoma pallidepennis的粪便材料中检测到了多环类拟鞭毛体，这使得该病的急性期能够及时进行治疗。
