Trypanosomatids are parasites widely distributed in nature, parasitizing several host species in single or co-infections. Campo Grande (CG), capital of Mato Grosso do Sul State, is characterized by several green areas and forest fragments where wild mammals have been reported infected by diverse trypanosomatid species. In this study, we evaluated the parasitism by trypanosomatids in the non-human primates (NHP) Sapajus cay and sampled in three different areas of CG.
For the detection of infections and identification of trypanosomatid species, we made hemoculture, blood smears, molecular and serological tests.
We detected trypanosomatids in 37/55 (67.3%) of sampled animals, all by the molecular test. DNA sequencing analyzes were performed on 32 samples, resulting in the following species identification: , , , infantum and (species already recorded in primates in Latin America), and for the first time , a parasite related to small mammals, and sp. DID, originally reported in marsupials sp.
The detection of trypanosomatids of public health importance as , and (genotypes TcI, TcII/TcVI and TcIV) indicates the enzootic character of these species in the studied area. Also, the presence of TcIV and in the conservation area supports previous studies that these parasites would be associated with the arboreal stratum. We conclude that (i) the NHP at CG participate in a complex reservoir system for parasites of great importance for Public Health in the studied area, such as , and , and (ii) there is a great diversity of trypanosomatids circulating in the urban area of this city located in the Brazilian Midwest.
锥虫是广泛分布于自然界的寄生虫,可单独或合并感染多种宿主物种。南马托格罗索州首府大坎普市(Campo Grande,简称CG)有多个绿地和森林碎片,据报道野生哺乳动物感染了多种锥虫物种。在本研究中,我们评估了锥虫在非人类灵长类动物(NHP)卡耶卷尾猴(Sapajus cay)中的寄生情况,并在大坎普市的三个不同区域进行了采样。
为了检测感染情况并鉴定锥虫物种,我们进行了血液培养、血涂片、分子和血清学检测。
我们在37/55(67.3%)的采样动物中检测到了锥虫,均通过分子检测。对32个样本进行了DNA测序分析,结果鉴定出以下物种: 、 、 、婴儿利什曼原虫(Leishmania infantum)和 (这些物种已在拉丁美洲的灵长类动物中记录),首次发现了 ,一种与小型哺乳动物相关的寄生虫,以及DID锥虫属(Trypanosoma sp. DID),最初在有袋动物 属(Didelphis sp.)中报道。
检测到具有公共卫生重要性的锥虫,如 、 和 (基因型TcI、TcII/TcVI和TcIV),表明这些物种在研究区域具有动物流行病特征。此外,保护区中存在TcIV和 ,支持了先前的研究,即这些寄生虫与树栖层有关。我们得出结论:(i)大坎普市的非人类灵长类动物参与了一个复杂的宿主系统,该系统对于研究区域公共卫生具有重要意义的寄生虫,如 、 和 ,起着重要作用;(ii)在巴西中西部这座城市的市区,有多种锥虫在传播。
