the recent evolution of a maternally-inherited endosymbiont of ticks led to the emergence of the q fever pathogen, coxiella burnetii.q fever is a highly infectious disease with a worldwide distribution. its causative agent, the intracellular bacterium coxiella burnetii, infects a variety of vertebrate species, including humans. its evolutionary origin remains almost entirely unknown and uncertainty persists regarding the identity and lifestyle of its ancestors. a few tick species were recently found to harbor maternally-inherited coxiella-like organisms engaged in symbiotic interactions, but their relationships to the q fever ...201525978383
a new argasid tick species (acari: argasidae) associated with the rock cavy, kerodon rupestris wied-neuwied (rodentia: caviidae), in a semiarid region of brazil.the rock cavy kerodon rupestris (wied-neuwied, 1820) is a rodent species endemic to northeastern brazil. earlier studies have associated the argasid tick ornithodoros talaje (guérin-méneville, 1849) with rocky cavy; however, a recent study proposed that o. talaje is not established in brazil, where previous reports of this species were possibly misidentifications of closely related species, yet to be properly determined. here, we describe a new species of ornithodoros koch, 1844 associated with ...201627655282
ornithodoros peruvianus kohls, clifford & jones (ixodoidea: argasidae) in chile: a tentative diagnosis.three argasid tick larvae were collected on april 2, 2010, from a common vampire bat, desmodus rotundus, captured in the parque nacional pan de azúcar (26°09' s, 70°41' w), region of atacama, chile. the larvae were diagnosed as ornithodoros, and further comparative analysis showed them to be ornithodoros peruvianus kohls, clifford & jones or a species close to it. phylogenetic analysis based on 16s mitochondrial rrna gene sequences of ornithodoros species plus four argas species was carried out ...201223950013
