Abstract:

Rickettsia prowazekii, the etiologic agent for epidemic typhus, and Borrelia recurrentis, the etiologic agent of relapsing fever, both utilize the same vector, the human body louse (Pediculus humanus), to transmit human disease. We have developed an assay to detect both bacterial pathogens in a single tube utilizing real-time PCR. Assays for both agents are specific. The R. prowazekii and B. recurrentis assays do not detect nucleic acid from R. typhi, R. canada, or any of eight spotted fever rickettsiae. In addition they did not react with Neorickettsia risticii, N. sennetsu, Franciscella persica, Bartonella quintana, Legionella pneumophila, Proteus mirabilis, Salmonella enterica, Escherichia coli, and Staphylococcus aureus. Moreover, the B. recurrentis assay did not detect B. duttonii, B. coriaceae, B. afzelii, B. garinii, B. hermsii, or B. burgdorferi nucleic acid. Both assays detected repeatedly only R. prowazekii or B. recurrentis either when tested alone or together in one test tube.
