Clinical cases
Cytological Diagnosis of Nocardiosis in a Cat
A clinical case of suspected nocardiosis in a cat: cytology of a mediastinal granuloma, Romanowsky negative staining, and bacterial acid-fastness.
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.
