For the first time in the world literature, the presented study describes oral-anal contact between two sympatric and ticks, which are the vectors of many pathogens in Europe. Among the specimens collected in nature, an male was found with the hypostome and chelicerae inserted in the anal aperture of a female. Given the biological and physiological traits of both species and microorganisms colonising these arthropods, it seems that the interspecific oral-anal contacts between ticks may be an unknown alternative route of transmission of pathogenic and symbiotic microorganisms present in ticks' alimentary tract, faeces, body surface, and in the haemolymph and organs, taking place when the male's mouthparts are inserted into the female's body. The authors suggest that interspecific contacts between ticks in natural conditions can contribute to the spread of some icroorganisms among different tick species and their hosts..
在世界文献中，本研究首次描述了两种同域蜱之间的口肛接触，这两种蜱是欧洲许多病原体的传播媒介。在自然界采集的标本中，发现一只雄性蜱的口下板和螯肢插入了一只雌性蜱的肛门孔。考虑到这两种蜱的生物学和生理特征以及定殖于这些节肢动物的微生物，当雄性蜱的口器插入雌性蜱的体内时，蜱之间的种间口肛接触似乎可能是蜱消化道、粪便、体表、血淋巴和器官中存在的致病和共生微生物的一种未知的传播途径。作者认为，自然条件下蜱之间的种间接触可能有助于某些微生物在不同蜱种及其宿主之间传播。
