The epidemiology of infection in rural Mexico is largely unknown. Therefore, we sought to determine the seroprevalence of infection in rural people in a northern Mexican state. We performed a cross-sectional seroprevalence study of 641 people living in rural Durango State including 282 subjects of the general population, 214 subjects of Huichol ethnicity, and 145 subjects of Mennonite ethnicity. Sera of participants were analyzed for the presence of anti immunoglobulin G (IgG) antibodies using a commercially available enzyme immunoassay. Three (0.5%) of the 641 subjects tested were positive for anti- IgG antibodies. Of the 3 seropositive subjects, two were females, aged 19 and 39 years, and one was male, aged 59 years. They had contacted with dogs, cleaned cat excrement, consumed unwashed raw fruits, contacted soil, or lived in a house with soil floors. Seroprevalence of infection was similar among the 3 groups of population studied: 0.4% for the general population, 0.9% for Huicholes, and 0.0% for Mennonites (P = 0.41). In conclusion, the seroprevalence found in subjects in rural Durango is low as compared with those reported in people from rural areas in other countries.
墨西哥农村地区感染的流行病学情况很大程度上尚不明确。因此，我们试图确定墨西哥北部一个州农村人口中的感染血清阳性率。我们对杜兰戈州农村地区的641人进行了一项横断面血清阳性率研究，其中包括282名普通人群、214名惠乔尔族受试者和145名门诺派受试者。使用市售酶免疫测定法分析参与者血清中抗免疫球蛋白G（IgG）抗体的存在情况。641名接受检测的受试者中有3人（0.5%）抗IgG抗体呈阳性。在这3名血清阳性受试者中，两名是女性，年龄分别为19岁和39岁，一名是男性，年龄为59岁。他们曾接触过狗、清理过猫粪便、食用过未清洗的生水果、接触过土壤或居住在泥土地面的房屋中。在所研究的3组人群中，感染的血清阳性率相似：普通人群为0.4%，惠乔尔族为0.9%，门诺派为0.0%（P = 0.41）。总之，与其他国家农村地区人群的报告相比，杜兰戈州农村地区受试者的血清阳性率较低。
