We detected Rickettsia parkeri in 20%-33% of Amblyomma maculatum ticks sampled in North Carolina. Results highlight the high frequencies of R. parkeri-infected ticks in the state with the highest annual incidence of Rocky Mountain spotted fever. Epidemiologic studies are needed to definitively link R. parkeri to cases of spotted fever rickettsiosis.
我们在北卡罗来纳州采集的 20%-33%的孤星蜱中检测到了帕克氏立克次体。这些结果突出表明,在该州,帕克氏立克次体感染的孤星蜱出现的频率很高,而该州正是落矶山斑点热的年发病率最高的州。需要开展流行病学研究来明确将帕克氏立克次体与斑点热立克次体病病例联系起来。
