seroprevalence of seven pathogens transmitted by the ixodes ricinus tick in forestry workers in order to assess the level of occupational exposure to the main pathogens transmitted by the ixodes ricinus tick, a seroprevalence study was performed on serum samples collected in 2003 from 2975 forestry workers of northeastern france. the global seroprevalence estimated for the seven pathogens studied was 14.1% (419/2975) for borrelia burgdorferi sl, 5.7% (164/2908) for francisella tularensis, 2.3% (68/2941) for tick-borne encephalitis virus, 1.7% (50/2908) for anaplasma phagocytophilum and ...201627237545
prevalence of borrelia burgdorferi sensu lato and anaplasmataceae members in ixodes ricinus ticks in alsace, a focus of lyme borreliosis endemicity in france.due to the high lyme borreliosis incidence in alsace, in northeastern france, we investigated in 2003-2004 three cantons in this region in order to determine the density of ixodes ricinus ticks infected by borrelia burgdorferi sensu lato and anaplasmataceae. the peak density of nymphs infected by b. burgdorferi sensu lato at munster and guebwiller, where the disease incidence was high, was among the highest reported in europe (105 and 114 per 100 m(2), respectively). in contrast, the peak densit ...200616598024
