spp., spp. and are common zoonotic pathogens in humans and animals. Although rodents are important parts of the ecosystem and common hosts for these pathogens, little is known of the distribution, genetic diversity and zoonotic potential of these pathogens in wild rodents. A total of 442 fecal samples were collected from eleven wild rodent species in three provinces of China, and analyzed for these pathogens by PCR and DNA sequencing. The infection rates of spp., spp. and were 19.9% (88/442), 19.8% (75/378) and 12.2% (54/442), respectively. Altogether, 23 known species/genotypes were identified and their distribution varied among different sampling locations or rodent species. Subtyping of the zoonotic species identified two novel subtype families XVe and XVf in , the subtype family XIIh and a novel subtype family XIIj in , and the subtype family IId in . Three species were identified, including ( = 57), ( = 15) and ( = 3), with assemblages A and G identified in brown rats in urban areas of Guangdong. In addition, 13 genotypes including eight known and five novel ones were identified, belonging to Groups 1, 2, 10, 14 and 15. Within nine genotypes in the zoonotic Group 1, common human-pathogenic genotypes D, Type IV, PigEbITS7 and Peru8 were detected only in brown rats and Lesser rice-field rats in urban areas of Guangdong. Apparent host adaptation and geographical differences were observed among spp., spp. and genotypes in wild rodents in the present study. Furthermore, the zoonotic species and genotypes commonly found here suggest a high zoonotic potential of these pathogens in wild rodents, especially in brown rats in urban areas. Hygiene and One Health measures should be implemented in urban streets and food stores to reduce the possible direct and indirect transmission of these rodent-related pathogens.
[病原体名称1]属、[病原体名称2]属和[病原体名称3]是人和动物中常见的人畜共患病原体。尽管啮齿动物是生态系统的重要组成部分,也是这些病原体的常见宿主,但对于这些病原体在野生啮齿动物中的分布、遗传多样性和人畜共患病潜力知之甚少。从中国三个省份的11种野生啮齿动物中总共收集了442份粪便样本,并通过聚合酶链反应(PCR)和DNA测序对这些病原体进行分析。[病原体名称1]属、[病原体名称2]属和[病原体名称3]的感染率分别为19.9%(88/442)、19.8%(75/378)和12.2%(54/442)。总共鉴定出23种已知的[病原体名称4]物种/基因型,它们的分布在不同采样地点或啮齿动物物种之间有所不同。对人畜共患的[病原体名称4]物种进行亚型分析,在[病原体名称4]中鉴定出两个新的亚型家族XVe和XVf,在[病原体名称5]中鉴定出亚型家族XIIh和一个新的亚型家族XIIj,在[病原体名称6]中鉴定出亚型家族IId。鉴定出三种[病原体名称7]物种,包括[病原体名称7]物种1(n = 57)、[病原体名称7]物种2(n = 15)和[病原体名称7]物种3(n = 3),在广东市区的褐家鼠中鉴定出[病原体名称7]组合A和G。此外,鉴定出13种[病原体名称8]基因型,包括8种已知的和5种新的基因型,属于第1、2、10、14和15组。在人畜共患的第1组中的9种基因型中,常见的人类致病基因型D、IV型、PigEbITS7和Peru8仅在广东市区的褐家鼠和小田鼠中检测到。在本研究中,观察到野生啮齿动物中[病原体名称1]属、[病原体名称2]属和[病原体名称8]基因型之间存在明显的宿主适应性和地理差异。此外,这里常见的人畜共患的[病原体名称4]物种和[病原体名称8]基因型表明这些病原体在野生啮齿动物中,尤其是在市区的褐家鼠中具有很高的人畜共患病潜力。应在城市街道和食品商店实施卫生和“同一健康”措施,以减少这些与啮齿动物相关的病原体可能的直接和间接传播。
