We analyzed the food sources of Bolivian wild Triatoma infestans (the main vector of Chagas disease in this country), to assess the role of these populations in the epidemiological context of Chagas disease. Ninety-eight blood meals were identified by heteroduplex assay and sequencing. Most of them were from wild mammals but surprisingly 27 were from humans. This brings to light the occurrence of human-vector contacts at risk of Trypanosoma cruzi transmission in the wild environment by highly infected insects.
我们分析了玻利维亚野生 Triatoma infestans（该国恰加斯病的主要传播媒介）的食物来源，以评估这些种群在恰加斯病流行病学背景中的作用。通过异源双链分析和测序鉴定了 98 份血餐。它们大多来自野生哺乳动物，但令人惊讶的是，有 27 份来自人类。这表明在野外环境中，高度感染的昆虫会导致人类与传播克氏锥虫的媒介之间发生接触。
