Amblyomma hebraeum, a cattle tick common in southern Africa, was demonstrated to be capable of maintaining an infection with an unclassified spotted fever group rickettsia both transtadially and transovarially. All feeding stages of the tick transmitted the infection to rabbits. The rickettsia was isolated and found to be serotypically distinct from three strains of Rickettsia conorii by microimmunofluorescence. Rabbit serum titers were found to be higher with indirect fluorescent antibody (IFA) tests using the Amblyomma isolate than with those using a commercially available IFA test for R. conorii.
希伯来花蜱是一种在非洲南部常见的牛蜱，已证明它能够经变态期和经卵期传播一种未分类的斑点热群立克次氏体感染。蜱的所有取食阶段都能将感染传播给兔子。该立克次氏体被分离出来，通过微量免疫荧光法发现其血清型与三株康氏立克次氏体不同。使用希伯来花蜱分离株进行间接荧光抗体（IFA）检测时，兔子血清滴度高于使用市售的康氏立克次氏体IFA检测时的血清滴度。
