detection of rickettsia spp. and anaplasma phagocytophilum in ixodes ricinus ticks in a region of middle germany (thuringia).rickettsia spp. and anaplasma spp. are regarded as potentially emerging tick-borne pathogens, but so far data on prevalence rates in questing ticks and reports on human diseases in several parts of europe are rarely available. in this study, 430 nymphs and 570 adult ixodes (i.) ricinus ticks were collected from a frequently visited forest region of thuringia (zeitzgrund, near stadtroda) in 2006 (n=506) and 2007 (n=494). individual ticks were investigated for a part of the citrate synthase gene ( ...201021771511
prevalence of granulocytic ehrlichiae in ixodes ricinus ticks in middle germany (thuringia) detected by pcr and sequencing of a 16s ribosomal dna fragment.a total of 305 ixodes ricinus ticks (243 nymphs and 62 adults) were collected from three different regions of thuringia in middle germany which are known to be endemic for borrelia burgdorferi. our aim was to investigate the carrier rate of ticks for granulocytic ehrlichia species. the presence of ehrlichial 16s ribosomal dna was investigated by polymerase chain reaction. using primers specific for the ehrlichia phagocytophila group pcr fragments of 151 bp and 943 bp, respectively, were produced ...200212076817
prevalence of four species of borrelia burgdorferi sensu lato and coinfection with anaplasma phagocytophila in ixodes ricinus ticks in central germany.a total of 305 ixodes ricinus ticks collected from three areas of thuringia in central germany were investigated for infection with borrelia burgdorferi sensu lato species and anaplasma phagocytophila. overall, 11.1% were infected with borrelia burgdorferi and 2.3% with anaplasma phagocytophila. adult ticks showed a significantly higher rate of infection with both borreliae and anaplasma phagocytophila. borrelia garinii (55.9%) was detected most frequently, followed by borrelia burgdorferi sensu ...200312783276
