When I was a Post-doc, I mainly worked for detection and/or isolation of pathogens, including Rickettsia, Ehrlichia, Anaplasma and Bartonella, in blood-sucking arthropods such as ticks, fleas, and keds, and their host animals. In Obihiro University of Agriculture and Veterinary Medicine, I am studying the detection of tick-borne pathogens from dogs and ticks (Fig. 1) on them, the detection and separation of rickettsia and bartonella from Hokkaido squirrels and its parasitic flea (Fig. 2 and 3). Recently, I am collecting blood-sucking arthropods on raccoons, and searching for pathogens in raccoons and these arthropods.
These surveys show what kind of / how much pathogens exist in the living environment of dogs, cats, and humans, and risks of infection of these pathogens to dogs, cats and humans, which can contribute to protecting animal and human health.
