Research Themes
Analysis of intra-species diversity in intestinal protozoan parasites using molecular taxonomy
Reveal the intra-species diversity within the population of each intestinal protozoan parasite from an evolutionary viewpoint to construct a novel prevention approach using selection pressures against the spread of drug-resistant parasites.
Epidemiologic analysis regarding parasitic burdens in endemic areas
To maintain the international co-operational relationships with partners in endemic tropical countries, and to fight against expected pandemics of protozoal infectious diseases, several field works in those areas are ongoing.
