蜱和蜱传病原体对人类和动物健康构成巨大威胁。本研究旨在确定感染骆驼的蜱的患病率,并调查骆驼血液中蜱传播的病原体的存在,相关的蜱,和周围的啮齿动物作为水库。从100只被检查的骆驼中,来自吉萨省的不同地方,收集了1000只ixodid蜱;这些蜱属于三个属:Hyalomma,弱视,还有Rhipicephalus.Hyalomma属由四个物种代表,口蹄疫是最普遍的物种(55.4%),其次是出土风琴(22%),风孔炎(11.6%)和风孔炎(2.8%)。Amblyomma属由两个物种代表,双球(2.8%)和双球(2.7%),虽然根皮法菌只代表一个物种,胸甲(2.7%)。滴答,骆驼血,和啮齿动物(总数为100只棕色大鼠)筛选蜱传播的病原体(伯氏疏螺旋体,miyamotoiBorreliamiyamotoi,巴贝西亚。,和伯氏柯西氏菌)使用PCR。骆驼血被发现感染了伯氏疏螺旋体(66.6%),miyamotoi疏螺旋体(55%),和Babesiasp.(11.6%)。在所有收集的蜱中都检测到了柯西氏菌DNA,但在骆驼或啮齿动物的血液中未检测到。在12.5%的H.impeltatum中检测到miyamotoi,55%的骆驼和6%的啮齿动物,这可能表明拟传播B.miyamotoi的风险,蜱传复发性发热的药剂.
Ticks and tick-borne pathogens pose a great threat to human and animal health. The present study aimed to determine the prevalence of ticks that infest camels and investigate the presence of tick-borne pathogens in the blood of camels, associated ticks, and surrounding
rodents as reservoirs. From 100 inspected camels, from different localities in the Giza governorate, 1000 ixodid ticks were collected; these ticks belonged to three genera: Hyalomma, Amblyomma, and Rhipicephalus. The genus Hyalomma was represented by four species, Hyalomma dromedarii was the most prevalent species (55.4%), followed by Hyalomma excavatum (22%), Hyalomma impeltatum (11.6%) and Hyalomma rufipes (2.8%). The genus Amblyomma was represented by two species, Amblyomma gemma (2.8%) and Amblyomma marmoreum (2.7%), while the genus Rhipicephalus was represented by only one species, Rhipicephalus pulchellus (2.7%). Ticks, camel blood, and
rodents (total number 100 brown rats) are screened for tick-borne pathogens (Borrelia burgdorferi, Borrelia miyamotoi, Babesia sp., and Coxiella burnetii) using PCR. Camel blood was found to be infected with Borrelia burgdorferi (66.6%), Borrelia miyamotoi (55%), and Babesia sp. (11.6%). Coxiella burnetii DNA was detected in all the collected ticks but was not detected in the blood of camels or
rodents. Borrelia miyamotoi was detected in 12.5% of H. impeltatum, 55% of Camels, and 6% of the
rodents, which may indicate a proposed risk of dispersal of B. miyamotoi, the agent of tick-borne relapsing fever.
