In South Carolina, 1974-1980, only two matches were found between 536 Rocky Mountain spotted fever (RMSF) cases and 965 individuals who submitted ticks that tested rickettsial antigen positive. In neither case did the positive test prevent RMSF. Tick rickettsial positivity rates varied inversely with human RMSF attack rates in different geographic areas. A physician survey established it as unlikely that RMSF occurred in positive tick submitters (PTS), and that although not recommended, 34 per cent of asymptomatic PTS received prophylactic treatment. Only 18 per cent of positive ticks were engorged. Tick testing appears ineffective in preventing RMSF.
在南卡罗来纳州，1974年至1980年期间，在536例落基山斑疹热（RMSF）病例与965名提交立克次体抗原检测呈阳性蜱虫的个体之间，仅发现两例匹配情况。在这两例中，阳性检测均未能预防落基山斑疹热。不同地理区域的蜱虫立克次体阳性率与人类落基山斑疹热发病率呈负相关。一项医生调查表明，落基山斑疹热不太可能发生在蜱虫检测呈阳性的提交者（PTS）身上，并且尽管不推荐，但34%无症状的PTS接受了预防性治疗。仅18%的阳性蜱虫处于饱血状态。蜱虫检测在预防落基山斑疹热方面似乎无效。
