蜱是是自然界吸血媒介中仅次于蚊虫的第二大传播媒介,在叮咬人畜吸血的过程中传播多种病原体,引发蜱媒传染病。蜱的共生微生物种类繁多,包括细菌、真菌等,不仅影响蜱的营养、繁殖和代谢,对病原体的存活、定殖及蜱的传病能力也起着决定性作用。血餐是蜱的唯一营养来源,也是影响其共生细菌变化的主要因素。不同来源的血餐、以及血餐的消化程度等均可影响蜱的共生细菌组成和多样性。本文总结了血餐对蜱类共生细菌多样性的影响,以期为利用共生细菌开展蜱媒病的防控积累资料。
Tick is the second largest transmission medium in the blood-sucking media in the world, second only to mosquitoes. It spreads a variety of pathogens during the bite of blood-sucking animals and causes tick-borne diseases. Toxoplasma symbiotic microorganisms, including bacteria, fungi, etc., not only affect the nutrition, reproduction and metabolism of ticks, but also play a decisive role in the survival of pathogens, colonization and the transmission of ticks. Blood meal is the only source of ticks nutrition, but also affect the symbiotic bacterial changes in the main factors. Different sources of blood meal, as well as the degree of digestion of blood meal and so on can affect the commensal bacterial composition and diversity of ticks. This paper summarizes the impact of blood meal on the diversity of tick symbiotic bacteria in order to carry out the prevention and control of tick-borne diseases using symbiotic bacteria.
