Microbiology Case: Sputum Culture in Pneumonia
A clinical microbiology case: sputum from a patient with severe pneumonia was examined. Identify the pathogen based on growth on BCYE agar and colony microscopy.
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.
