Abstract

The addition of cholesterol to a liquid medium containing bovine serum albumin (BSA) fraction V or acetone-delipidized BSA fraction V instead of serum stimulated the growth of , a serum-requiring spirochaete associated with swine dysentery. As little as 1·25 g cholesterol ml increased viable counts about 1000-fold. Sitosterol and cholestanol, but not pregnenalone, cholestenone or stigmasterol, produced a growth response comparable to that of cholesterol. The results suggest that requires a sterol for growth.
