摘要
立克次体病(表1)正在全世界出现。沉寂了数十年后,毁灭性的斑疹伤寒(普氏立克次体)大流行再次出现,并且斑疹热在旅行者中越来越多地被确认。至少已确认了6种新的立克次体斑疹热(瑞士立克次体,帕氏立克次体,猫立克次体,斯洛伐克立克次体,黑龙江立克次体和aeschlamanni立克次体)。立克次体病经节肢动物媒介传播。主要的感染宿主是人类(普氏立克次体)和小型哺乳动物(斑疹伤寒立克次体和斑疹热组)。
Rickettsial diseases (Figure 1) are emerging worldwide. Following decades of quieseence, devastating epidemics of typhus fever (Rickellsia prowazekii) have reappeared, and spotted fevers are increasingly recognized in travellers. At least six new rickettsial spotted fevers (R.helvetica, R.parkeri, R felis, R. slovaca R. heilongjiangensis and R.aeschlamannii) have been characterized.
