在这里，我们提出了一个审查的数据集，导致从11年的后续行动的克氏锥虫感染的自由放养的种群Leontopithecus罗萨利亚（金狮绢毛猴）和Leontopithecus chrysomelas（金头狮绢毛猴）从不同的森林片段在大西洋沿岸雨林。此外，我们提出了新的数据，T。与金狮绢毛猴生活在同一地区的小型哺乳动物（啮齿动物和有袋动物）的克氏感染，并在离散分型单位（DTU）水平上对77个这些分离株进行了表征。DTU TcII被发现只感染灵长类动物，而TcI感染Didelphis aurita和狮子绢毛猴。大多数T.克氏乳杆菌分离株来自L.罗萨利亚为Tc Ⅱ型（33/42）。cruzi分离株显示TcI谱。金头狮绢毛猴是TcII的良好储库，26只中有24只。cruzi分离株显示TcII谱。结果表明：（1）T. cruzi在同一宿主物种和森林片段是随着时间的推移修改，（ii）金狮绢毛猴人口的感染能力波动波，每隔一年达到峰值，（iii）黄金和金头狮绢毛猴都能够保持长期持久的感染TcII和TcI。
Here, we present a review of the dataset resulting from the 11-years follow-up of Trypanosoma cruzi infection in free-ranging populations of Leontopithecus rosalia (golden lion tamarin) and Leontopithecus chrysomelas (golden-headed lion tamarin) from distinct forest fragments in Atlantic Coastal Rainforest. Additionally, we present new data regarding T. cruzi infection of small mammals (rodents and marsupials) that live in the same areas as golden lion tamarins and characterisation at discrete typing unit (DTU) level of 77 of these isolates. DTU TcII was found to exclusively infect primates, while TcI infected Didelphis aurita and lion tamarins. The majority of T. cruzi isolates derived from L. rosalia were shown to be TcII (33 out 42) Nine T. cruzi isolates displayed a TcI profile. Golden-headed lion tamarins demonstrated to be excellent reservoirs of TcII, as 24 of 26 T. cruzi isolates exhibited the TcII profile. We concluded the following: (i) the transmission cycle of T. cruzi in a same host species and forest fragment is modified over time, (ii) the infectivity competence of the golden lion tamarin population fluctuates in waves that peak every other year and (iii) both golden and golden-headed lion tamarins are able to maintain long-lasting infections by TcII and TcI.
