| molecular identification of borrelia genus in questing hard ticks from portugal: phylogenetic characterization of two novel relapsing fever-like borrelia sp. | in the last decades, several studies have reported pathogenic species of borrelia related to those that cause tick-borne relapsing fever (rf), but unexpectedly suggesting their transmission by hard ticks, known vectors of borrelia burgdorferi sensu lato (b. burgdorferi s.l.) species, rather than by soft ticks. this study was designed to update the presence of b. burgdorferi s.l. species in ticks from several districts of mainland portugal, where ixodes ricinus had been previously described. tick ... | 2016 | 26976475 |
