Leptospirosis is the most common bacterial zoonosis globally. The pathogen, Leptospira spp., is primarily associated with rodent reservoirs. However, a wide range of other species has been implicated as reservoirs or dead-end hosts. We conducted a survey for Leptospira spp. in bats and rodents from Papua New Guinea. Kidney samples were collected from 97 pteropodid bats (five species), 37 insectivorous bats from four different families (six species) and 188 rodents (two species). Leptospires were detected in a high proportion of pteropodid bats, including Nyctimene cf. albiventer (35%), Macroglossus minimus (34%) and Rousettus amplexicaudatus (36%). Partial sequencing of the secY gene from rodent and bat leptospires showed host species clustering, with Leptospira interrogans and L. weilii detected in rodents and L. kirschneri and a potential novel species of Leptospira detected in bats. Further research is needed in Papua New Guinea and other locales in the Pacific region to gain a better understanding of the circulation dynamics of leptospires in reservoir species and the risks to public and veterinary health.

钩端螺旋体的多样性。在巴布亚新几内亚的蝙蝠和啮齿动物中

钩端螺旋体病是全球最常见的细菌性人畜共患病。病原体钩端螺旋体属主要与啮齿动物宿主有关。然而，广泛的其他物种被认为是宿主或死胡同。我们对钩端螺旋体进行了一项调查。在巴布亚新几内亚的蝙蝠和啮齿动物中。从 97 只翼足类蝙蝠（5 个物种）、来自 4 个不同科的 37 只食虫蝙蝠（6 个物种）和 188 只啮齿动物（2 个物种）中收集了肾脏样本。在高比例的翼足类蝙蝠中检测到钩端螺旋体，包括Nyctimene cf. albiventer (35%)、Macroglossus minimus (34%) 和Rousettus amplexicaudatus (36%)。的部分测序来自啮齿动物和蝙蝠钩端螺旋体的secY基因显示宿主物种聚类，在啮齿动物中检测到问号钩端螺旋体和L. weilii ，在蝙蝠中检测到 L. kirschneri和潜在的钩端螺旋体新种。需要在巴布亚新几内亚和太平洋地区的其他地方进行进一步研究，以更好地了解宿主物种中钩端螺旋体的循环动态以及对公众和兽医健康的风险。
