Rickettsial zoonotic diseases, in particular scrub typhus, murine typhus, and tick typhus, are caused by Orientia tsutsugamushi, Rickettsia typhi, and Rickettsia honei infections. Rickettsiae exposure is typically related to a rodent host in various habitats of marginal regions, including between rural areas and communities such as the Salaya suburb. This allows the oriental house rat (OHR), a highly adaptive species, to live in close proximity to the community and possibly introduce rickettsial diseases. To understand rickettsial exposure in the OHR from different habitats, knowledge of disease exposure can serve as baseline information for disease management and prevention. A total of 185 OHRs from three unrelated habitats were assessed using a standard indirect immunofluorescence assay (IFA) for specific antibody reaction to O. tsutsugamushi, R. typhi, and R. honei. The presence of antibody in the OHR to rickettsiae, either scrub or murine typhus, was associated with the habitat, whereas tick typhus had general exposure. This finding shows the OHR to be a potential reservoir host for rickettsial diseases along the borders of geographic regions in the suburban environment.

立克次体人畜共患病，特别是灌木斑疹伤寒，鼠类斑疹伤寒和tick虫病，是由Or虫东方虫，斑疹伤寒立克次氏体和本氏立克次体引起的感染。立克次体的暴露通常与边缘地区的各种栖息地中的啮齿动物寄主有关，包括在农村地区和Salaya郊区等社区之间。这使高度适应的物种东方家鼠（OHR）可以在社区附近生活，并可能引入立克次氏病。为了了解OHR来自不同栖息地的rick病暴露，对疾病暴露的了解可以作为疾病管理和预防的基准信息。使用特异性抗体反应的标准间接免疫荧光试验（IFA）来自三个不相关的栖息地总共185个OHRs进行了评估恙虫病东方体，R.伤寒沙门氏菌，和R. honei。OHR中针对立克次体（灌木或鼠类斑疹伤寒）的抗体的存在与栖息地有关，而壁虱斑疹伤寒则普遍存在。这一发现表明，OHR可能是郊区环境中沿地理区域边界的病的潜在宿主。
