Kitasato+Shibasaburō

 **Kitasato Shibasaburō** (January 29, 1853- June 13, 1931):

Shibasaburō was a Japanese physician and bacteriologist. He is most acclaimed for being the co-discoverer of the bubonic plague’s infectious agent. He, alongside Alexandre Yersin, discovered the agent on a federally-financed expedition, in Hong Kong in 1894. Kitasato was born in the Higo Province of Japan; he was later educated at Kumamoto Medical School, as well as at Tokyo's Imperial University. After completing his studies at these two schools, Shibasaburo travelled to the Univerisity of Berlin to study under the famous Dr. Roberth Koch. His time there, spanning 1886-1891 would include several startling discoveries and developments. In 1889, he was the first person to grow pure, cultured tetanus bacillus, and then, in 1890, he worked with Emil von Behring to create a serum therapy for tetanus using this pure culture. He was also heavily involved in developing antitoxins for anthrax, as well as diphtheria. Kitasato, along with his colleagues at Berlin, demonstrated the great advances that his new antitoxins provided in preventing disease, as they each produced a passive immunity to tetanus in an animal, even after having tetanus-infected blood passed through their circulatory system. After completing his work in Berlin, Shibasaburo returned to Japan in 1891. Once there, he founded the Institute for Study of Infectious Diseases, along with his co-founder and provider. Soon after the creation, he was able to demonstrate how dead cultures of bacteria and disease can be used to help create and improve vaccinations. [1]
