the prevalence of borrelia burgdorferi sensu lato in ixodes persulcatus and i. ricinus ticks in the zone of their sympatry.a total of 7210 unfed adult ixodes persulcatus schulze, 1930 and i. ricinus (l., 1758) ticks were collected from the vegetation by flagging in 35 study sites located in the zone of their sympatry (mainly in leningrad region, russia). borrelia infection in ticks was estimated by the dark-field microscopic analysis of gut contents in standard vital preparations at a magnification of x600. no correlation was revealed between the series of parameters characterising the abundance of each tick species ...200111266136
