| Research Abstract |
Forty one blood, 29 spleen, and 475 flea samples were taken from a total of 66 red squirrels in Tokachi region, Hokkaido. No rickettsial agent were detected from blood and spleen samples, however, 69 (20.2%) of 342 flea samples of which tick species were identified were positive for Rickettsiaspecies. Partial sequences of 4 genes of detected rickettsiae were determined, which were close to Rickettsiafelis. Fifteen fleas were used for isolation of rickettsiae, and rickettsial agent was successfully isolated from one flea.
