The Etiology, Mode of Infection, and Specific Therapy of Weil's Disease (spirochætosis Icterohæmorrhagica)

In this communication we have summarized and in some details extended the publications on this subject which have appeared in the Japanese literature. 1 In the course of our investigations of that endemic disease of portions of Japan, which agrees clinically with Well's disease, so called, we discovered a spiroch~etal microorganism which is now believed to be the cause of the disease. In the experiments recorded in this paper, Drs. Inada, Ido, Hoki, and Ito chiefly conducted the experiments on animals, and Dr. Kaneko the pathological and anatomical observations.
