Chagas disease is caused by the protozoan Trypanosoma cruzi. Seven lineages have been identified based on different molecular markers, namely TcI, TcII, TcIII, TcIV, TcV, TcVI, and TcBat. Dogs play the role of epidemiological sentinels being domestic reservoirs of T. cruzi. The aim of the current study was to report the first case of CD in a domestic dog in Manaus, Amazonas, Brazil, infected with T. cruzi DTU TcIV. We hope our report encourages veterinarians and surveillance professionals to a take a deeper look at T. cruzi infection in domestic animals.
查加斯病由原生动物克氏锥虫引起。根据不同的分子标记，已确定了 7 个谱系，即 TcI、TcII、TcIII、TcIV、TcV、TcVI 和 TcBat。狗作为流行病学哨兵，是克氏锥虫的家养宿主。本研究的目的是报告在巴西亚马孙州玛瑙斯的一只家养狗中首例 CD 病例，该狗感染了 TcIV 型 DTU 的克氏锥虫。我们希望我们的报告能鼓励兽医和监测专业人员更深入地研究家养动物中的克氏锥虫感染。
