Transmission of a spotted fever group rickettsia by Amblyomma hebraeum (Acari: Ixodidae).
Kelly PJ, Mason PR. Kelly PJ, et al. J Med Entomol. 1991 Sep;28(5):598-600. doi: 10.1093/jmedent/28.5.598. J Med Entomol. 1991. PMID: 1941925
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 i

Almost 100% of 52 cattle tested from the southern areas of Zimbabwe were found to have antibodies reactive with Rickettsia conorii compared with less than 30% of 120 cattle from the north. Steers artificially infected with R. conorii isolated from Amblyomm

They were, however, distinguishable from other SFG ricketsiae by MIF serotyping and in the case of the most closely related serotypes, Rickettsia conorii and the Israeli SFG rickettsia, by SDS-PAGE and Western blot. PCR-RFLP failed to distinguish between the …
