No anthracocidines are found in the serum of clinically healthy men and women in their menstrual interval. The serum of clinically healthy women contains bactericidal elements against anthrax bacilli during menstruation, disappearing after 14 days. The blood of the umbilical vein of newborn contains bactericidines against anthrax and typhus bacilli. Sera of clinically sick persons contain copious amounts of anthracocidines in febrile, acute and chronic infectious diseases in infectious diseases without fever chronic tuberculosis, syphilis, rheumatism in diseases of the blood in chronic diseases with organic changes, such as hepatic afflictions, cardiac and vascular diseases and chronic renal affections in serious injuries and operations with extensive scarifying processes. Therapy may increase the formation of anthracocidines, but excessively large doses may also cause them to disappear. The coincidence of different, severe organic diseases seems to have the same effect. Fifty sera killed both anthrax and typhus bacilli.
