Trypanosoma cruzi hosts can serve as a source of infection for animals, vectors, and humans, contributing to the establishment of Chagas disease (CD) in a given area. Traditionally, the Department of Córdoba has not been considered a transmission area for CD; however, the report of several acute cases of Chagas disease highlights the importance of studying the dynamics of disease transmission in this region. This study aimed to detect T. cruzi in domestic and wild mammals in the department of Córdoba. In 2017, a cross-sectional descriptive study was conducted in six villages in two municipalities in the department of Córdoba. Blood samples from dogs living in the zones were collected in EDTA vacutainer tubes for domestic mammals. Wild mammals were collected using Sherman and Tomahawk traps and mist nets in crops and peridomiciles. T. cruzi DNA was detected using the kinetoplast DNA (kDNA) variable region and the tandem repeat satellite region of T. cruzi as molecular targets. We sampled 168 dogs and 146 wild mammals. The detected prevalence of T. cruzi was 6.37%; the TcI lineage was found in , , and one canine. A specimen of with TcI and TcII lineages was also identified. T. cruzi DNA was detected in domestic and wild animals in the study area, indicating the circulation of the parasite in peridomestic environments. may represent an important host in maintaining this region's wild and domestic cycle.
克氏锥虫宿主可成为动物、传播媒介和人类的感染源,促使查加斯病(CD)在特定地区传播。传统上,科尔多瓦省未被视为查加斯病的传播地区;然而,几例查加斯病急性病例的报告凸显了研究该地区疾病传播动态的重要性。本研究旨在检测科尔多瓦省家养和野生哺乳动物体内的克氏锥虫。2017年,在科尔多瓦省两个市的六个村庄开展了一项横断面描述性研究。对于家养哺乳动物,将生活在这些区域的狗的血液样本采集到含有乙二胺四乙酸(EDTA)的真空采血管中。对于野生哺乳动物,在农田和房屋周围使用谢尔曼陷阱、战斧式陷阱和捕雾网进行捕捉。以克氏锥虫的动质体DNA(kDNA)可变区和串联重复卫星区作为分子靶点,检测克氏锥虫DNA。我们对168只狗和146只野生哺乳动物进行了采样。检测到的克氏锥虫感染率为6.37%;在[此处原文缺失部分信息]和一只犬类中发现了TcI谱系。还鉴定出了一只同时具有TcI和TcII谱系的[此处原文缺失部分信息]标本。在研究区域的家养和野生动物中检测到了克氏锥虫DNA,这表明该寄生虫在家居周边环境中传播。[此处原文缺失部分信息]可能是维持该地区野生和家养传播循环的重要宿主。
