| Research Abstract |
This study revealed that as a rickettsia showing the pathogenicity to humans, Rickettsia felis DNA was detected from cat fleas(0.6%) and flea feces (8.2%) collected from cats for the first time in Japan. Furthermore, R. typhi DNA was also detected from a cat flea (0.3%) derived from a cat. R. monacensis DNA was also detected from ticks (2.1%) on dogs. Furthermore, DNA of genus Bartonella, which is a causative agent of the cat scratch disease was detected for the first time in Japan from cat fleas and their feces. Besides, DNA of genus Rickettsia and Bartonella which were different from any known species and have been unidentified for their pathogenicity were also detected in this study. It will be necessary to examine the actual situation of the infected person with these Rickettsia or Bartonella in near future.
