Abstract
Several spotted fever group rickettsiae (SFGR) previously believed to be nonpathogenic are speculated to contribute to infections commonly misdiagnosed as Rocky Mountain spotted fever (RMSF) in the United States, but confirmation is difficult in cases with mild or absent systemic symptoms. We report an afebrile rash illness occurring in a patient 4 days after being bitten by a Rickettsia montanensis-positive Dermacentor variabilis tick. The patient's serological profile was consistent with confirmed SFGR infection.
摘要
几种先前被认为无致病性的斑点热群立克次体（SFGR）据推测在美国会导致通常被误诊为落基山斑点热（RMSF）的感染，但对于症状轻微或无全身症状的病例，确诊很困难。我们报告了一例发热性皮疹疾病，该患者在被一只感染蒙大拿立克次体的变异革蜱叮咬4天后发病。患者的血清学特征与确诊的SFGR感染一致。
