Hedgehogs are small mammals. They are potential reservoirs of various zoonotic agents. This study was conducted in Bouira, a north-central region of Algeria. A total of 21 Atelerix algirus corpses were picked up on roadsides and gardens. Hedgehog kidneys, spleens and ectoparasites were collected. Twelve hedgehogs were infested with ectoparasites, including Archaeopsylla erinacei, Rhipicephalus sanguineus s.l. and Haemaphysalis erinacei. Hedgehog organs and randomly selected arthropods were screened for microorganisms using molecular methods. Coxiella burnetii was detected in kidneys, spleens, A. erinacei, Hae. erinacei and Rh. sanguineus s.l. Leptospira interrogans was detected in kidneys. Rickettsia felis and Rickettsia massiliae were detected respectively in A. erinacei and in Rh. sanguineus s.l. DNA of an uncultivated Rickettsia spp. was found in Hae. erinacei. Wolbachia spp. DNA was detected in fleas. The DNA of potential new Bartonella and Ehrlichia species were found respectively in fleas and ticks. This study highlights the presence of DNA from a broad range of microorganisms in hedgehogs and their ectoparasites that may be responsible for zoonoses in Algeria.
刺猬是小型哺乳动物,它们可能是多种人畜共患病原体的储存宿主。本研究在阿尔及利亚中北部的布维拉进行。共从路边和花园中收集了 21 只 Atelerix algirus 尸体。采集了刺猬的肾脏、脾脏和外寄生虫。其中 12 只刺猬被外寄生虫寄生,包括 Archaeopsylla erinacei、Rhipicephalus sanguineus s.l. 和 Haemaphysalis erinacei。使用分子方法对刺猬器官和随机选择的节肢动物进行了微生物筛查。在肾脏、脾脏、A. erinacei、Hae. erinacei 和 Rh. sanguineus s.l. 中检测到了柯克斯体。在肾脏中检测到了钩端螺旋体。在 A. erinacei 和 Rh. sanguineus s.l. 中分别检测到了无形体和马赛利亚无形体。在 Hae. erinacei 中发现了一种未培养的无形体 spp.DNA。在跳蚤中检测到了沃尔巴克氏体 spp.DNA。在跳蚤和蜱中分别发现了潜在的新巴尔通体和埃立克体属的 DNA。本研究强调了阿尔及利亚刺猬及其外寄生虫中存在多种微生物的 DNA,这些 DNA 可能是导致人畜共患病的原因。
