美洲锥虫病在美国国内传播周期中的宿主-媒介-寄生虫相互作用尚不清楚。克氏锥虫（动质体目：对从德克萨斯州中部住宅环境收集的成年和未成熟锥蝽（半翅目：猎蝽科）标本确定了锥蝽科（锥虫科）感染率和血粉来源。从锥蝽消化道中获得的细胞色素B DNA片段的测序鉴定了四种锥蝽（Triatoma gerstaeckeri，Triatoma indictiva，Triatoma protracta和Triatoma sanguisuga）中的九种脊椎动物宿主和一种无脊椎动物宿主。广泛的野生和国内的宿主物种检测锥蝽标本从住宅区表明高主机的多样性和潜在的运动之间的森林和peridomestic设置。家犬作为锥蝽病媒的血液宿主和寄生虫的潜在宿主，似乎是维持国内传播周期的关键。T.从室内、室外和犬舍采集的锥蝽标本中的克氏锥蝽感染率（分别为69%、81%和82%）表明，由于与森林循环重叠，德克萨斯州住宅环境中的人类和家畜目前存在恰加斯病媒介传播的风险。
The host–vector–parasite interactions in Chagas disease peridomestic transmission cycles in the United States are not yet well understood. Trypanosoma cruzi (Kinetoplastida: Trypanosomatidae) infection prevalence and bloodmeal sources were determined for adult and immature triatomine (Hemiptera: Reduviidae) specimens collected from residential settings in central Texas. Sequenced cytochrome b DNA segments obtained from triatomine digestive tract identified nine vertebrate hosts and one invertebrate host in four triatomine species (Triatoma gerstaeckeri, Triatoma indictiva, Triatoma protracta, and Triatoma sanguisuga). The broad range of wild and domestic host species detected in triatomine specimens collected from residential sites indicates high host diversity and potential movement between the sylvatic and peridomestic settings. Domestic dogs appear to be key in the maintenance of the peridomestic transmission cycle as both a blood host for the triatomine vectors and a potential reservoir for the parasite. The high rate of T. cruzi infection among triatomine specimens that were collected from inside houses, outside houses, and dog kennels (69, 81, and 82%, respectively) suggests a current risk for Chagas disease vector-borne transmission for humans and domestic animals in residential settings in Texas because of overlap with the sylvatic cycle.
