The world currently faces severe biodiversity losses caused by anthropogenic activities such as deforestation, pollution, the introduction of exotic species, habitat fragmentation, and climate changes. Disease ecology in altered environments is still poorly understood. The golden-headed lion tamarin (GHLT, Leontopithecus chrysomelas) is an endangered species that became invasive in an urban park in Niterói, Rio de Janeiro, Brazil. The initially few invasive GHLT individuals became hundreds, adapted to living in proximity to humans and domestic animals. These GHLTs were captured as part of a conservation project; some animals were translocated to Bahia and some were kept in captivity. This study tested 593 GHLT for Leptospira serology; 100 and 95 GHLT for polymerase chain reaction (PCR) toLeptospira and hepatitis E virus genotype 3 (HEV-3), respectively, and 101 familiar groups for PCR to viruses (rotavirus A, norovirus GI and GII, and HEV-3). One animal had antibodies for Leptospira serovar Shermani and another for serovar Hebdomadis. One saprophyticLeptospira was found by the 16S PCR and sequencing. Viruses were not detected in samples tested. Findings suggest that the epidemiological importance of such pathogens in this GHLT population is either low or nonexistent. These data are important to understand the local disease ecology, as well as monitoring a translocation project, and to contribute data for species conservation.
目前，世界正面临着由人类活动如森林砍伐、污染、引入外来物种、栖息地破碎化和气候变化等导致的严重生物多样性丧失。在改变的环境中，疾病生态学仍未得到充分理解。金头狮狨（GHLT，Leontopithecus chrysomelas）是一种濒危物种，已入侵巴西里约热内卢尼泰罗伊市的一个城市公园。最初的少数入侵 GHLT 个体变成了数百个，适应了与人类和家畜生活在一起。这些 GHLT 是作为保护项目的一部分被捕获的；一些动物被转移到巴伊亚，一些被圈养。本研究对 593 只 GHLT 进行了钩端螺旋体血清学检测；对 100 只和 95 只 GHLT 进行了聚合酶链反应（PCR）检测，以检测钩端螺旋体和戊型肝炎病毒基因型 3（HEV-3），对 101 个熟悉的群体进行了 PCR 检测，以检测病毒（轮状病毒 A、诺如病毒 GI 和 GII 以及 HEV-3）。一只动物对钩端螺旋体血清型 Shermani 有抗体，另一只对血清型 Hebdomadis 有抗体。通过 16S PCR 和测序发现了一种腐生的钩端螺旋体。在测试的样本中未检测到病毒。研究结果表明，这些病原体在该 GHLT 种群中的流行病学重要性较低或不存在。这些数据对于了解当地疾病生态学、监测迁徙项目以及为物种保护提供数据非常重要。
