“…In Japan, a spotted fever group (SFG) rickettsiosis was first recognized in 1984, in Tokushima Prefecture of Shikoku (5,10,12). The causative agent was isolated from the blood of a patient with febrile exanthematous illness in Kochi Prefecture of Shikoku (14,16).…”

To clarify the geographic distribution of spotted fever group (SFG) rickettsiae in Japan, small field rodents captured in endemic and nonendemic areas were screened for anti-SFG rickettsia antibodies by the immunofluorescence test. Among total 716 specimens tested, 73-75% of rodents were antibody-positive against Rickettsia japonica and/or Rickettsia montana, showing different degree of antibodypositive proportions among each species of the rodents. Interestingly, these profiles were not different in the rodents from each endemic and nonendemic areas, indicating that the SFG rickettsiae are prevailing in the wider areas where patients have not been found yet.

The polymerase chain reaction (PCR) was applied for the etiological diagnosis of spotted fever group (SFG) rickettsiosis in Japan. Nucleotide primers derived from the 17-kDa antigen gene of Rickettsia rickettsii primed a rickettsia-specific 246-base-pair product for all of the Katayama, Abe, Misaka and Kojima strains, which we had isolated previously. Moreover, we were able to detect the same product by PCR amplification from the peripheral blood of a patient in the acute stage of the illness. The PCR method is considered to be useful for rapid etiological diagnosis of SFG rickettsiosis in Japan.
