In recent years, zoonotic diseases that infect from animals to human beings has become a problem. Infection can occur by microorganisms such as viruses, bacteria, parasites multiply in the body. On the other hand, there exist a number of microorganisms in the environment around us. Food poisoning, dogs and cats, and the like pet of infectious diseases, pathogenic microorganisms that blood-sucking insects carry, such as mosquitoes and ticks, the human number of bacteria also in the intestinal and skin and mouth inhabit. In other words, all living creatures, including us human beings we must live while coexisting with microorganisms. The Center, we believe microorganisms and correctly Tsukiaeru, and by knowing the nature of the microorganism correctly. Therefore, we developed a correctly quickly perform technical inspection of microorganisms, we have established a system prevent the spread of infectious diseases. The Center, mammals, birds, reptiles, amphibians, fish, insects, ranging from the plant, has developed a research subject a microorganism that infects all living creatures. I think people often Leaning the question “Do not the Center for Infectious Diseases of livestock?”. Infection of all the creatures, any by such as the food chain affect the livestock, and the last will Oyobi to human beings. For this reason, we believe that it is important to study the infection of all the creatures on this earth. Of course, only the researchers and students who belong to our center because it does not have this big challenge is accomplished, I have conducted joint research with many universities and research institutes. Through the infectious disease research, we will continue to contribute to the society in which all living creatures Revitalizing. Center Mizutani Tetsuya
