“…infection in rodents was 17.0%, lower than that in rodents from the Qinghai-Tibetan Plateau (30.1%, Yu et al, 2022a), the Shangdang Basin (37.4%, Yu et al, 2022b), the Qaidam Basin (38.6%, Rao et al, 2021), Heixiazi Island (57.7%, Li et al, 2015, Shaanxi (26.1%, An et al, 2020), Zhongtiao Mountain (49.5%, Yu et al, 2022c), Zhejiang (31.4%, Liu et al, 2010), and South China (43.5%, Ying et al, 2002, while higher than that in rodents from eastern China (8.4%, Qin et al, 2019) and Guangzhou (6.4%, Yao et al, 2022). In addition, similar detection rates to those found in the present study were observed in rodents from Guizhou (16.1%; Lu et al, 2022) and southeastern China (14.9%; Liu et al, 2022). The discrepancy might have been due to the rodent species, habitats, and arthropod vector populations (Meheretu et al, 2013).…”

“…R. norvegicus and A. agrarius are the predominant species found in residential areas and the wild, respectively, and they can also act as the hosts of Bartonella spp. In previous studies, at least seven validated Bartonella species, namely, B. elizabethae, B. grahamii, B. rattimassiliensis, B. rochalimae, B. tribocorum, B. mastomydis, and B. queenslandensis, were identified in R. norvegicus (Qin et al, 2019;An et al, 2020;Liu et al, 2022;Yao et al, 2022;Yu et al, 2022c), and six species, namely, B. fuyuanensis, B. grahamii, B. phoceensis, B. japonica, B. taylorii, and B. coopersplainsensis, were identified in A. agrarius (Li et al, 2015;Qin et al, 2019;Lu et al, 2022;Yu et al, 2022b). In the present study, eight official or candidate Bartonella species, in addition to B. vinsonii-like species, were identified in rodents.…”

Rodents are the primary natural reservoirs of Bartonella spp., and some of which are zoonotic causative agents. Hence, surveillance of Bartonella sp. infection in rodents is very important for the prevention of human bartonellosis caused by them. In this study, rodents were captured, and their spleen samples were collected for Bartonella sp. DNA detection and identification by amplifying the 16S rRNA, gltA, and ftsz genes using semi-nested polymerase chain reaction (PCR). The results indicated that Bartonella sp. DNA was detected in seven Rattus norvegicus individuals with a detection rate of 6.7% in Chengde City and bacterial DNA in 31 Apodemus agrarius individuals with a detection rate of 28.4% in Handan City. The DNA detection rate across the genders and ages of rodents was not found to be statistically significant. Furthermore, sequence analysis of the above-mentioned three genes demonstrated that at least eight Bartonella species were circulating in Hebei Province, of which three, including Bartonella rattimassiliensis, Bartonella grahamii, and Bartonella tribocorum, are human pathogens, thus suggesting the existence of a major public health risk. Overall, these results revealed the detection rate and genetic diversity of Bartonella species infection in rodents in Hebei Province, which could be potentially helpful for the prevention of bartonellosis caused by rodent-associated Bartonella species. This study highlights the urgent need for the surveillance of Bartonella infections in rodents and ectoparasites that affect both rodents and humans and can cause fever of unknown origin or endocarditis.

“…Rodents play an important role in the interspecies transmission of SFGR from, and recent surveys have shown significant diversity, prevalence, and geographic distribution of Rickettsial bacteria in rodents [37,49]. It was reported that the prevalence of SFGR were 13.95%, 16.05%, and 33.3% in southeast, southwest, and south of China, respectively [50][51][52]. However, SFGR was mostly found in the species of R. tanezumi in Henan province in our study, with a lower prevalence of 7.3%.…”

Rodents and shrews are major reservoirs of various pathogens that are related to zoonotic infectious diseases. The purpose of this study was to investigate co-infections of zoonotic pathogens in rodents and shrews trapped in four provinces of China. We sampled different rodent and shrew communities within and around human settlements in four provinces of China and characterised several important zoonotic viral, bacterial, and parasitic pathogens by PCR methods and phylogenetic analysis. A total of 864 rodents and shrews belonging to 24 and 13 species from RODENTIA and EULIPOTYPHLA orders were captured, respectively. For viral pathogens, two species of hantavirus (Hantaan orthohantavirus and Caobang orthohantavirus) were identified in 3.47% of rodents and shrews. The overall prevalence of Bartonella spp., Anaplasmataceae, Babesia spp., Leptospira spp., Spotted fever group Rickettsiae, Borrelia spp., and Coxiella burnetii were 31.25%, 8.91%, 4.17%, 3.94%, 3.59%, 3.47%, and 0.58%, respectively. Furthermore, the highest co-infection status of three pathogens was observed among Bartonella spp., Leptospira spp., and Anaplasmataceae with a co-infection rate of 0.46%. Our results suggested that species distribution and co-infections of zoonotic pathogens were prevalent in rodents and shrews, highlighting the necessity of active surveillance for zoonotic pathogens in wild mammals in wider regions.

“…Azospirillum is an aerobic or microaerophilic bacterium typically associated with plant roots and can promote plant growth by nitrogen fixation [44]. Members of the groups Paracaedibacter [45] and Ehrlichia are known as intracellular parasites [46]. The general similarity or dissimilarity between the bacterial communities was well reflected by the correlation plots of OTU abundances.…”

This metagenomics investigation of three closely adjacent sampling sites from an archaeological excavation of a pre-industrial coal mining exploration shaft provides detailed information on the composition of the local soil bacterial communities. The observed significant differences between the samples, reflected in the 16S r-RNA analyses, were consistent with the archaeologically observed situation distinguishing the coal seam, the rapidly deposited bright sediment inside an exploration shaft, and the topsoil sediment. In general, the soils were characterized by a dominance of Proteobacteria, Actinobacteria, Acidobacteria, and Archaea, whereas the coal seam was characterized by the highest proportion of Proteobacteria; the topsoil was characterized by very high proportions of Archaea—in particular, Nitrosotaleaceae—and Acidobacteria, mainly of Subgroup 2. Interestingly, the samples of the fast-deposited bright sediment showed a rank function of OTU abundances with disproportional values in the lower abundance range. This could be interpreted as a reflection of the rapid redeposition of soil material during the refilling of the exploration shaft in the composition of the soil bacterial community. This interpretation is supported by the observation of a comparatively high proportion of reads relating to bacteria known to be alkaliphilic in this soil material. In summary, these investigations confirm that metagenomic analyses of soil material from archaeological excavations can provide valuable information about the local soil bacterial communities and the historical human impacts on them.
