Morphology of Giardia duodenalis Trophozoite: Anatomy
Anatomical structure of Giardia duodenalis trophozoite: nuclei, adhesive disc, flagella, and median bodies. Morphological markers of Giardia in the laboratory.
Articles
Blood and bone marrow morphology, clinical cases and diagnostic algorithms. Most of the library is in Russian; the English section is growing.
Most of our material is written in Russian — that is the working language of the community. A few pieces exist in English; the rest of the library is one click away and the photographs need no translation.
