Electron Microscopy Of Giardia Lamblia In Human Jejunal Biopsies

Abstract

SUMMARY A description is given of the ultrastructure of Giardia lamblia found in three jejunal biopsies from children. The unique median body, vacuoles and cytoplasmic clefts of this protozoon are illustrated. No evidence of penetration of the trophozoite into the jejunal mucosa or deeper tissues is demonstrable. This work was supported in part by a Grant from the Wellcome Trust to one of the authors (S. E. H. B.).
