Abstract

Ticks are primary vectors for many tick-borne pathogens (TBPs) and pose a serious threat to veterinary and public health. Information on the presence of TBPs in Chinese Milu deer (Elaphurus davidianus) is limited. In this study, a total of 102 Chinese Milu deer blood samples were examined for Anaplasma spp., Theileria spp., Babesia spp., Rickettsia spp., and Borrelia spp., and three TBPs were identified: Anaplasma phagocytophilum (48; 47.1 %), Candidatus Anaplasma boleense (47; 46.1%), and Theileria capreoli (8; 7.8 %). Genetic and phylogenetic analysis of the 16S rRNA and 18S rRNA confirmed their identity with corresponding TBPs. To our knowledge, this is the first report on Candidatus A. boleense and T. capreoli detection in Chinese Milu deer. A high prevalence of A. phagocytophilum with veterinary and medical significance was identified in endangered Chinese Milu deer, which could act as potential zoonotic reservoirs. The identification of the TBPs in Chinese Milu deer provides useful information for the prevention and control of tick-borne diseases.

首次在麋鹿中筛查蜱媒病原体

蜱是许多蜱媒病原体（TBPs）的主要传播媒介，对兽医和公共卫生构成严重威胁。有关中国麋鹿（Elaphurus davidianus）中存在蜱传病原体的信息十分有限。本研究共检测了 102 份麋鹿血液样本，以检测阿纳普拉斯马属、泰勒氏菌属、巴贝斯氏菌属、立克次体属和包柔氏菌属，并确定了三种 TBPs：噬细胞嗜血无形体（48；47.1%）、布氏无形体（47；46.1%）和毛癣菌（8；7.8%）。16S rRNA 和 18S rRNA 的遗传和系统进化分析证实了它们与相应 TBPs 的一致性。据我们所知，这是首次在中国麋鹿中检测到 A. boleense 和 T. capreoli 的报告。在濒临灭绝的中国麋鹿中发现了具有兽医和医学意义的噬菌体，而麋鹿可能是潜在的人畜共患传染源。对麋鹿中蜱虫的鉴定为预防和控制蜱传疾病提供了有用的信息。

期刊介绍： Ticks and Tick-borne Diseases is an international, peer-reviewed scientific journal. It publishes original research papers, short communications, state-of-the-art mini-reviews, letters to the editor, clinical-case studies, announcements of pertinent international meetings, and editorials. The journal covers a broad spectrum and brings together various disciplines, for example, zoology, microbiology, molecular biology, genetics, mathematical modelling, veterinary and human medicine. Multidisciplinary approaches and the use of conventional and novel methods/methodologies (in the field and in the laboratory) are crucial for deeper understanding of the natural processes and human behaviour/activities that result in human or animal diseases and in economic effects of ticks and tick-borne pathogens. Such understanding is essential for management of tick populations and tick-borne diseases in an effective and environmentally acceptable manner.
