Hippoboscid flies (Diptera: Hippoboscidae), commonly known as keds or louse flies, have been for long time overlooked by the scientific community, and their vector role of infectious agents to humans and domestic animals has been scantly investigated. This is partly due to the fact that the host range for most species is primarily restricted to wildlife, being rarely reported on domestic animals and humans. This led to a scarce scientific knowledge about their biology, ecology, behaviour, epidemiology as well as vector competence. However, the life history of some hippoboscid species, e.g., Melophagus ovinus, Lipoptena cervi and Hippobosca equina, suggests that these ectoparasites are important candidates to vector infectious disease agents (e.g., Rickettsia spp., Borrelia spp., Bartonella spp.; Anaplasma phagocytophilum, Theileria ovis). Indeed, the peculiar biological and behavioural traits (i.e., obligatory blood sucking and reproductive physiology) of many ked species make them a suitable pabulum for pathogen's multiplication and for their transmission to receptive hosts. Therefore, studies focusing on the ked bio-ecological aspects as well as on their vector role are advocated along with the control of keds affecting different animal species. This review discusses current information on keds, highlighting their importance as vectors of pathogens of medical and veterinary concern to all animal species, with a special focus on mammals.

Keds,神秘的苍蝇及其作为病原体的媒介。

长期被科学界忽视的通常称为科克斯蝇或虱子蝇的沙棘蝇(Diptera:Hippoboscidae),并且已经很少研究了传染原在人类和家畜中的媒介作用。部分原因是大多数物种的寄主范围主要限于野生动植物,很少有家畜和人类报道。这导致对其生物学,生态学,行为,流行病学以及媒介能力的科学知识匮乏。但是,某些河马类物种的生活史,例如卵圆叶兔,子宫颈鳞翅目和马鞭草,表明这些体外寄生虫是传染病媒介的重要候选物(例如,立克次氏菌,伯氏疏螺旋体,巴尔通体属;嗜酸细胞吞噬细胞,Theileria ovis)。确实,许多ked物种的独特的生物学和行为特征(即,必须吸血和生殖生理)使它们成为病原体繁殖和向病原体传播的合适宝库。因此,提倡着眼于ked生物生态学方面及其载体作用的研究,以及对影响不同动物物种的ked的控制。这篇评论讨论了关于keds的最新信息,强调了它们作为所有动物物种的医学和兽医关注病原体的载体的重要性,特别关注哺乳动物。提倡着重研究科德生物生态方面及其载体作用的研究,以及控制影响不同动物物种的科德。这篇评论讨论了关于keds的最新信息,强调了它们作为所有动物物种的医学和兽医关注病原体的载体的重要性,特别关注哺乳动物。提倡着重研究科德生物生态方面及其载体作用的研究,以及控制影响不同动物物种的科德。这篇评论讨论了关于keds的最新信息,强调了它们作为所有动物物种的医学和兽医关注病原体的载体的重要性,特别关注哺乳动物。
