We recently diagnosed rickettsial spotted fever in four patients from the south-eastern coastal region of South Australia near Adelaide, an area not known to be endemic for this infection. All infections were acquired within the geographic range of Aponomma hydrosauri, the tick vector of Rickettsia honei. Infection by R. honei was confirmed in two patients. This extension of the known geographic range of R. honei infection may be explained, in part, by alterations in host-parasite ecology.
我们最近在南澳大利亚州阿德莱德附近东南沿海地区的四名患者中诊断出立克次体斑疹热，该地区并非已知的这种感染的地方性流行区。所有感染均在水龙硬蜱（Rickettsia honei的蜱传播媒介）的地理范围内获得。两名患者确诊感染了霍氏立克次体。霍氏立克次体感染已知地理范围的这种扩展，部分原因可能是宿主 - 寄生虫生态的改变。
