Casimir Davaine (March 19, 1812 – 14 October 1882) was a French physician known for his work in the field of microbiology. He was a native of Saint-Amand-les-Eaux, department of Nord. In 1850, Davaine along with French pathologist Pierre François Olive Rayer (1793–1867), discovered a certain microorganism in the blood of diseased and dying sheep. In the diseased blood, Rayer and Davaine observed the bacillus that is known today as ''Bacillus anthracis'', the causative bacterium of anthrax. Soon afterwards, Rayer published an essay on anthrax, thus providing the first comprehensive description of ''Bacillus anthracis''. In 1863 Davaine demonstrated that the anthrax bacillus could be directly transmitted from one animal to another. He was able to identify the causative organism, but was unaware of its true etiology. Later, German microbiologist Robert Koch researched the etiology of ''Bacillus anthracis'', and discovered its ability to produce "resting spores" that could stay alive in the soil for a long period of time to serve as a future source of infection.〔(Robert Koch ) by Thomas D. Brock〕 Casimir Davaine is also credited for pioneer work in the study of septicemia (blood poisoning). ==References== *Nancy Tomes ''The Gospel of Germs: Men, Women, and the Microbe in American Life'' * * * * 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Casimir Davaine」の詳細全文を読む スポンサード リンク
