Ehrlichioses, caused by species, are tick-borne diseases (TBDs) that affect animals and humans worldwide. This study aimed to investigate the molecular occurrence of spp. in 530 animals (155 Dromedary camels, 199 goats, 131 cattle, and 45 sheep) in the Benadir and Lower Shabelle regions of Somalia. Blood DNA samples were tested for PCR targeting and genes of spp. and and genes of . The obtained sequences were submitted for phylogenetic analyses. spp. were detected in 26.4% (140/530) of animals by -PCR, with the highest prevalence in dromedary camels (54.8%), followed by cattle (29.8%), goats (7.0%), and sheep (4.4%). Dromedary camels, cattle, and goats had significantly higher infection odds compared to sheep ( < 0.05). Among -PCR-positive samples, 76.9% (30/39) of cattle tested -positive, while other species were negative. was detected in 13.7% (18/131) of cattle by -PCR, but none were positive for the gene. Phylogenetic analysis confirmed in camels, sheep, and goats and in cattle, marking the first molecular evidence of in dromedary camels, sheep, and goats globally, and in cattle from Somalia. These findings emphasize the need for further research on its economic and public health impact.
埃立克体病由相关物种引起,是一种影响全球动物和人类的蜱传疾病(TBDs)。本研究旨在调查索马里贝纳迪尔和下谢贝利地区530只动物(155峰单峰骆驼、199只山羊、131头牛和45只绵羊)中相关物种的分子存在情况。对血液DNA样本进行聚合酶链反应(PCR)检测,靶向相关物种的特定基因以及其他相关基因。将获得的序列提交进行系统发育分析。通过特定PCR检测,在26.4%(140/530)的动物中检测到相关物种,单峰骆驼中的患病率最高(54.8%),其次是牛(29.8%)、山羊(7.0%)和绵羊(4.4%)。与绵羊相比,单峰骆驼、牛和山羊的感染几率显著更高(P<0.05)。在特定PCR阳性样本中,76.9%(30/39)的牛检测出另一种相关检测呈阳性,而其他物种为阴性。通过另一种PCR在13.7%(18/131)的牛中检测到某物种,但该基因均无阳性。系统发育分析在骆驼、绵羊和山羊中确认了一种情况,在牛中确认了另一种情况,这标志着全球单峰骆驼、绵羊和山羊中该情况的首个分子证据,以及索马里牛中另一种情况的首个分子证据。这些发现强调了对其经济和公共卫生影响进行进一步研究的必要性。
