Spirochaetosis in Man. Reenrrent fever (Fehris reciirrens) is 

 known as a spirochetosis and is caused by the Spirochaete recurrentis 

 s. Obermeierei discovered by Obermeier (1868). The affection is mani- 

 fested by severe febrile attacks lasting from 3 to 12 days, and recurring 

 after 2 "to 11 days. In most cases lasting recovery results after several 

 febrile attacks. The natural transmission appears to result through 

 the agency of blood-sucking arthropodes, possibly also by insects and 

 lice. According to the most recent observations of Iversen in Russia 

 the disease may be cured quickly and permanently with Ehrlich's 

 Amidoarsenobenzol. 



A similar affection in the tropics, the African recurrent fever, or 

 "tick fever," is produced by the Spirochaete Duttoni (according to 

 Koch identical with the above), and is transmitted to healthy man by 

 a tick (Arnithodor.us mouliata). (Schilling, Mense's Hand!), d. Tropen- 

 krankheiten, 1906, III, 668.) 



Since the discovery by Schaudinn of tine spirochaetes (Sp. pallida, 

 Treponema pallidum) in the syphilitic organs, syphilis is also con- 

 sidered as a spirochetosis. This view has received material support by 

 the splendid results of Ehrlich's chemotherapy. Besides a spirochete 

 (Sp. pertenuis) was found by Castellani, as a prol)able cause of the 

 disease in Framboesia tropica, a skin affection of the tropics which 

 clinically resembles syphilis. (A. f. Schiffs- u. Tr.openhyg., 1907, Xl, 22.)
