Scarce information on the seroprevalence of Trypanosoma cruzi among Amerindians is available, and the distribution of this disease in Mexican Indian populations is unknown. In this study, the presence of specific antibodies against T. cruzi among Teenek Amerindians in nine different communities located in San Luis Potosi State was analyzed. An average seroprevalence of 6.5% was found in these populations, suggesting that active transmission of disease occurs in this relatively isolated population in Mexico, and therefore, further studies should be conducted to identify risk factor associated to Chagas disease in other isolated populations across the country to determine the prevalence of Chagas disease in Mexican Amerindians.
关于美洲印第安人中克氏锥虫血清阳性率的信息稀缺，且该疾病在墨西哥印第安人群中的分布情况未知。在本研究中，分析了位于圣路易斯波托西州九个不同社区的蒂内克美洲印第安人中抗克氏锥虫特异性抗体的存在情况。在这些人群中发现平均血清阳性率为6.5%，这表明在墨西哥这个相对隔离的人群中存在疾病的活跃传播，因此，应该开展进一步研究，以确定该国其他隔离人群中与恰加斯病相关的风险因素，从而确定墨西哥美洲印第安人中恰加斯病的患病率。
