Studies were conducted from April through August during 1974 and 1975 on 30 randomly selected trapping sites in Wall Doxey State Park, Holly Springs National Forest, and 1.6 km south of the park in Marshall County, Mississippi to provide information on the occurrence of ticks involved in the maintenance and transmission of spotted fever-group rickettsiae in nature. Of 365 animals (14 species) collected, 186 (51%) were parasitized by 4,169 ticks. Species of ticks collected included: Dermacentor variabilis; Amblyomma americanum; Rhipicephalus sanguineus; Haemaphysalis leporispalustris; and Ixodes texanus. Of 2,105 ticks examined, 116 (5.5%) were positive for rickettsia-like organisms.
1974年和1975年4月至8月期间，在密西西比州马歇尔县霍利斯普林斯国家森林的沃尔多西州立公园以及该公园以南1.6公里处的30个随机选定的诱捕地点进行了研究，以获取有关自然界中参与斑点热群立克次体维持和传播的蜱虫发生情况的信息。在收集的365只动物（14种）中，有186只（51%）被4169只蜱虫寄生。收集到的蜱虫种类包括：变异革蜱；美洲钝缘蜱；血红扇头蜱；野兔血蜱；以及德克萨斯硬蜱。在检查的2105只蜱虫中，有116只（5.5%）对类立克次体生物呈阳性反应。
