Laboratory Diagnosis of Amoebiasis: Stool Microscopy
A clinical case of intestinal amoebiasis in a child: detection of Entamoeba histolytica trophozoites in a native stool smear and a Romanowsky-stained smear.
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.
