“…Even in places as distant as Japan, the prevalence of antibodies against SFGR in mice (mainly wood mice) is high (Morita et al 1990, Okabayashi et al 1996. In California too, a seroprevalence for SFGR of 14% has been reported for rodents (Adjemian et al 2008).…”

Limited information is available on the presence of rickettsial infection in humans and animal reservoirs in Spain. Exposure to spotted fever group rickettsia in healthy humans and in farm and wild animals in the Province of Burgos, Spain, was examined by serological methods. Rickettsial DNA was also sought by PCR in animal samples. Of 102 human serum samples examined by indirect immunofluorescence assays (IFA), 5.88% were positive for antibodies against Rickettsia conorii (titers 1/128-1/512). Significant differences were detected in human seroprevalence with respect to age. In further IFAs, 102 out of 375 (27.2%) serum samples from the wild animals reacted with R. conorii antigens (titers 1/64-1/1024); 32 out of 281 (11.38%) samples from farm animals were also positive for R. conorii (titers 1/64-1/2048). The prevalence detected among total wild animals was significantly higher than among total farm animals. No rickettsial DNA was found by PCR in any farm or wild animal sample.

“…Each of the entrapped animals was anesthetized, bled and 100 µl of blood was collected using blood-sampling filter paper (Toyo Roshi, Tokyo, Japan). The filter paper was then dried in air and stored at room temperature [7]. For PCR analysis, the paper-absorbed blood was eluted in 600 µl of phosphatebuffered saline (pH.…”

ABSTRACT. The first case of human babesiosis was reported in Japan. The epidemiology of this disease in Japanese nature remains unclear. In this study, 97 common field mice captured in Hokkaido, Japan, were examined. Blood specimens absorbed onto filter papers were eluted and tested by nested PCR using specific primers for the B. microti nuclear small subunit rRNA genome. Twenty-three percent (11/47) of Apodemus speciosus and four percent (2/50) of Clethrionomys rufocanus were positive. The 159-bp primary sequences of PCR products tested exhibited 97.5% and 96.8% homology with those of the human isolate in Japan and of U.S. strains of B. microti, respectively. KEY WORDS: Babesia microti, filter paper, rodent.
