Abstract

Background: Anaplasma spp. and Ehrlichia spp. are amongst the most important tick-transmitted bacteria that can cause zoonotic disease in various hosts including ruminants and humans.

Methods: In this study, 16srRNA, EE, and dsb sequences were respectively used to screen Anaplasmataceae family, Anaplasma spp., and Ehrlichia spp. in tick samples (n= 100) collected from 100 domestic ruminants including 50 sheep and 50 cattle in Jiroft City, southeast of Iran, between June and August 2021.

Results: two genera were predominant among the ticks including Hyalomma spp. (64%; 43% from sheep and 21% from cattle) and Rhipicephalus spp. (36%; 22% from cattle and 14% from sheep); all ticks were adult and 73% of them were male. DNA of Anaplasmataceae was detected in 17% (17/100) of the ticks collected from cattle (18%; 9/50) and sheep (16%; 8/50). Anaplasma spp. was not found in the samples, but two ticks were positive for Ehrlichia spp.; all were positive for Ehrlichia spp. belonged to the cattle (4%; 2/50).

Conclusion: This study shows that Anaplasmataceae strains are circulating via ticks among domestic ruminants in the study area, emphasizing the need for effective tick control strategies by livestock farmers, health, and veterinary authorities. Surveillance, molecular characterization and further sequencing-based studies are crucial for informed control and prevention efforts.

伊朗吉洛夫特市羊、牛蜱无原体科、无原体和埃利希体流行情况的快照研究。

背景：无原体和埃利希氏体是最重要的蜱传播细菌，可引起包括反刍动物和人类在内的各种宿主的人畜共患疾病。方法：本研究于2021年6 - 8月在伊朗东南部吉洛夫特市采集100只家养反刍动物（包括50只羊和50头牛）蜱虫样本，分别采用16srRNA、EE和dsb序列对蜱虫进行无形体科、无形体种和埃利希体种进行筛选。结果：蜱类以2属为主，其中透明蝇属占64%；43%来自绵羊，21%来自牛)和鼻头虫(36%；22%来自牛，14%来自羊)；所有蜱均为成虫，其中73%为雄蜱。从牛采集的蜱中，有17%（17/100）检出无浆虫科的DNA (18%；9/50)和羊(16%；8/50)。标本未检出无原体，但2只蜱检出埃利希体；所有病例均为埃利希氏体阳性。2/50)。结论：本研究表明无虫科菌株通过蜱在研究区家养反刍动物中传播，强调畜牧农民、卫生和兽医部门需要采取有效的蜱虫控制策略。监测、分子表征和进一步基于测序的研究对于知情控制和预防工作至关重要。
