Sand flies are the only accepted biological vectors of Leishmania parasites. However, secondary modes of transmission have been extensively discussed and speculated about in recent years. In particular, the hypothesis of ticks as vectors of Leishmania infantum was studied in the 20th century and today is being revisited using modern molecular biology techniques. Recent studies have shed new light on the discussion, but have also led to misleading conclusions on the role of ticks as Leishmania vectors. In this article, the role of brown dog ticks, Rhipicephalus sanguineus, as vectors of L. infantum is discussed, and the need for further research to better understand their participation in the epidemiology of leishmaniasis is advocated.
沙蝇是唯一被认可的利什曼原虫寄生虫的生物传播媒介。然而，近年来，人们广泛讨论和推测了次要的传播方式。特别是，在 20 世纪，人们研究了蜱作为利什曼原虫婴儿利什曼虫传播媒介的假说，而如今，这一假说正在利用现代分子生物学技术重新进行研究。最近的研究为这一讨论提供了新的视角，但也导致了对蜱作为利什曼原虫传播媒介的作用的误导性结论。在本文中，讨论了棕色犬蜱，即 Rhipicephalus sanguineus，作为利什曼原虫婴儿利什曼虫传播媒介的作用，并提倡进行进一步的研究，以更好地了解它们在利什曼病流行病学中的参与。
