Kiyoshi Shiga

Kiyoshi Shiga was a Japanese physician and bacteriologist.

Shiga was born in Sendai, Miyagi Prefecture, though his original family name was Sat. He graduated from the Medical School of Tokyo Imperial University in 1896 and went to work at the Institute for the Study of Infectious Diseases under Dr. Kitasato Shibasabur. Shiga became famous for the discovery of Shigella dysenteriae, the bacillus causing dysentery, in 1897, during a severe epidemic in which more than 90,000 cases were reported, with a mortality rate approaching 30. The bacterium Shigella was thus named after him, as well as the shiga toxin, which is produced by the bacterium.
