| Research Abstract |
Dogs and ticks infected with dogs in Hokkaido were examined for Rickettsia species using PCR and IFA. The rickettsial agent was detected by PCR in one canine blood sample, and the sequence analysis of the PCR product showed that the obtained sequence was closely related to R. felis. Serological survey showed that 8.9% of dogs had high serum titer to Rickettsia species, which revealed that large number of dogs in Hokkaido was exposed to rickettsial agents. Twenty-four percent of ticks infested with dogs harbored rickettsial agents, which suggested that dogs may bring rickettsial agents in ticks to the human environment.
Rickettsia species closely related to the rickettsial agent detected in dog was also detected in the flea infested with the squirrel, Sciurus vulgaris orientis, which may suggest that the flea has some role in transmission of rickettsiae to dogs.
