In Catolé do Rocha, State of Paraíba, Brasil several people were concomitantly contaminated by Chagas' disease and had the acute form of the infection. Because of this event, the hypothesis that Trypanosoma cruzi might have been transmitted by the digestive route, through the ingestion of accidentally contaminated sugar cane juice, was made. In the present study, we verified that the parasite has remained viable for four hours in the liquid, at room temperature. We have also demonstrated that, after one hour, it was capable of promoting infection in one mouse, by gastric tube administration. These observations enhance the interest on this alternative mechanism of disease transmission.
在巴西帕拉伊巴州的卡托莱杜罗查,数人同时感染了恰加斯病并呈急性感染形式。由于这一事件,人们提出了这样的假说:克氏锥虫可能通过消化道途径传播,即通过摄入意外被污染的甘蔗汁传播。在本研究中,我们证实该寄生虫在室温下的液体中可存活4小时。我们还证明,1小时后,通过胃管给药,它能够使一只小鼠感染。这些观察结果增加了人们对这种疾病传播替代机制的关注。
