Variety of trypanosome species had been reported from human and animal hosts. Interestingly, their virulence to hosts is ranging from avirulent to high that cause fatal trypanosomosis. Each trypanosome species has various phenotypes in terms of host/vector-parasite relationships, such as trypanosome species with high or low host specificity, different mode of transmission namely biological transmission, mechanical transmission, and sexual transmission. In addition, some species are parasitized into host cell, while others are obligate extracellular parasite, making them formidable enemies that will use whatever means necessary to survive. Unfortunately, our current control measures to combat trypanosomoses are limited, i.e., early diagnosis followed by isolation of patients and affected animals, treatment with drugs which often cause severe adverse effects, and vector control. To improve the current situation, we are conducting development of simpler, affordable, and more accurate diagnostic methods, safe therapeutic agents, and vaccines, as well as to analyze the prevalence and risk factors of the disease.

Another research project focuses on the survival strategies of trypanosomes as parasitic organisms. Trypanosomes can survive within their mammalian hosts and vectors (often insects), which have completely different internal environments. However, mechanisms of their life-cycle development and environmental adaptation are largely unknown. Our research is particularly focused on the identification and functional analysis of developmental stage-specific surface molecules. This basic research is also being conducted in the hope that it will lead to the development of future transmission blocking vaccines and therapeutics that target the cell differentiation mechanisms of trypanosomes.

Self introduction

I am from Tokushima Pref. My hobbies are reading and art appreciation. My specialty is parasitology and protozoology. I have been developing diagnostic methods for animal trypanosomoses, conducting epidemiological surveys, and studying the molecular mechanism of life cycle development of trypanosome. I have been an OIE Reference Laboratory Expert (Surra) since June 2007 to present.
