() ticks are the only known vectors of , an agent of tick-borne relapsing fever (TBRF) borreliosis. Rodents serve as principal natural reservoirs for . Our research objective was to detect TBRF and other zoonotic bacterial infections in ticks and in house mice , an invasive species currently expanding in rural northern Senegal. Real-time and conventional PCR were utilized for detecting and other bacterial taxa. The analyses were performed on 253 specimens of . and 150 samples of brain and spleen tissue from rodents. was found in one tick and 18 samples, with prevalences of 0.39 percent and 12 percent, respectively, as well as sp. in one . Further, we were able to detect the presence of a potentially infectious novel species belonging to the Anaplasmataceae family for the first time in ticks. More attention should be paid to the house mouse and ticks, as they can be potential hosts for novel species of pathogenic bacteria in humans.
()蜱虫是已知的唯一传播回归热疏螺旋体的媒介,回归热疏螺旋体是蜱传回归热(TBRF)疏螺旋体病的病原体。啮齿动物是回归热疏螺旋体的主要自然宿主。我们的研究目标是在蜱虫和家鼠中检测蜱传回归热疏螺旋体及其他人畜共患细菌感染,家鼠是一种目前正在塞内加尔北部农村地区扩散的入侵物种。利用实时荧光定量PCR和常规PCR检测回归热疏螺旋体及其他细菌类群。对253份蜱虫标本以及150份来自啮齿动物的脑和脾组织样本进行了分析。在1只蜱虫和18份家鼠样本中发现了回归热疏螺旋体,其患病率分别为0.39%和12%,并且在1只蜱虫中还发现了某种未明确的疏螺旋体。此外,我们首次在蜱虫中检测到了一种属于无形体科的具有潜在传染性的新物种。应更多关注家鼠和蜱虫,因为它们可能是人类致病性细菌新物种的潜在宿主。
