Wild nonhuman primates (NHP) are considered natural hosts of a protozoan parasite from the genus Leishmania, the etiological agent of leishmaniasis. It is important to study the population of this infectious agent in zoo animals to establish surveillance and control mechanisms in Sorocaba through the application of a One Health approach, this is where human–animal–environment health and disease interface and can aid in the protection of endangered species. This study aimed to identify Leishmania infantum and Leishmania braziliensis in NHP living in a city where leishmaniasis is endemic. DNA was extracted from 48 NHP and analyzed using polymerase chain reaction primers that are specific for the species L. infantum and L. braziliensis. The results of our research revealed the first report of L. infantum and L. braziliensis naturally infecting primates at Sorocaba zoo. One primate from the species Plecturocebus vieirai was positive for L. infantum and five primates (four Alouatta caraya and one Ateles chamek) were positive for L. braziliensis. This indicates a possible role of these animals on the maintenance of these parasites.

巴西动物园圈养灵长类动物中婴儿利什曼原虫和巴西利什曼原虫的鉴定

野生非人类灵长类动物 (NHP) 被认为是利什曼原虫属的原生动物寄生虫的天然宿主，利什曼原虫是利什曼病的病原体。重要的是研究动物园动物中这种传染性病原体的数量，以便通过应用 One Health 方法在索罗卡巴建立监测和控制机制，这是人类-动物-环境健康和疾病的界面，可以帮助保护动物濒危物种。本研究旨在识别生活在利什曼病流行城市的 NHP 中的婴儿利什曼原虫和巴西利什曼原虫。从 48 个 NHP 中提取 DNA，并使用对L. infantum和巴西乳杆菌。我们的研究结果揭示了L. infantum和L. braziliensis在索罗卡巴动物园自然感染灵长类动物的第一份报告。一种来自 Plecturocebus vieirai 物种的灵长类动物对L. infantum呈阳性，五种灵长类动物（四种Alouatta caraya 和一种Ateles chamek）对L. braziliensis 呈阳性。这表明这些动物在维持这些寄生虫方面可能发挥作用。
