Abstract:
This study aims to provide information on the occurrence of spotted fever rickettsiae in Ixodes ricinus ticks in southern Germany. A total of 2,141 I. ricinus ticks was collected in Bavaria. Pools of 5-10 ticks were studied by a PCR targeting the rickettsial citrate synthase gene gltA. The average prevalence rate was 12% (257 of 2,141). Sequencing data exclusively identified Rickettsia helvetica DNA. Results and other data demonstrate the possible role of R. helvetica in I. ricinus as a source of human infections in southern Germany.
