斑点热组立克次体感染是一个世界性的健康问题,以持续高烧为特征,头痛,和人类的皮疹,家畜,和野生动物。迄今为止,硬蜱中立克次体物种的发生尚未得到彻底研究,特别是在哈萨克斯坦东部和南部。共有1,245只成年蜱,包括734个皮肤边缘,219Hyalommascupense,144亚洲风琴,84Hyalommamarginatum,48根皮孢,和16个赤霉病,从东哈萨克斯坦收集,Abay,Jetsu,阿拉木图,Jambyl,南哈萨克斯坦和哈萨克斯坦的Qyzylorda州,用于使用分子方法筛选立克次体药物。立克次体劳尔蒂,立克次体Slovaca,通过测序鉴定了立克次体和黑龙江立克次体,31.5%(392/1245)的蜱携带立克次体。自然景观的差异解释了收集的蜱的多样性,并扩大了我们对立克次体物种及其在哈萨克斯坦的地理分布的了解。据我们所知,这项研究报告了哈萨克斯坦黑龙的首次发现。
Infections with spotted fever group rickettsiae represent a worldwide health problem, characterized by persistent high fever, headache, and rash in humans, domestic animals, and wildlife. To date, the occurrence of Rickettsia species in hard ticks has not been thoroughly studied, especially in eastern and southern Kazakhstan. A total of 1,245 adult ticks, comprising 734 Dermacentor marginatus, 219 Hyalomma scupense, 144 Hyalomma asiaticum, 84 Hyalomma marginatum, 48 Rhipicephalus turanicus, and 16 Haemaphysalis erinacei, collected from East Kazakhstan, Abay, Jetsu, Almaty, Jambyl, South Kazakhstan and Qyzylorda oblasts of Kazakhstan, were used to screen rickettsial agents using molecular methods. Rickettsia raoultii, Rickettsia slovaca, Rickettsia aeschlimannii and Rickettsia heilongjiangensis were identified using sequencing, and 31.5% (392/1245) of ticks carried rickettsial agents. The difference in the natural landscapes explains the variety of the collected ticks and expands our knowledge of Rickettsia species and their geographical distribution in Kazakhstan. To the best of our knowledge, this study reports the first finding of R. heilongjiangensis in Kazakhstan.
