Abstract
Bile salts and fatty acids stimulated differentiation of cultured Giardia lamblia trophozoites into water-resistant cysts at the slightly alkaline pH of the small intestinal lumen. Maximum encystation occurred at pH 7.8. Thus, specific small-intestinal factors may influence encystation in vivo as well as in vitro.
