[The scientific path of a laboratory of pathomorphology and electron microscopy]

The paper shows the research directions of the staff of the laboratory of pathomorphology and electron microscopy, which cover the period from 1924 to the present time, which can be conventionally divided into 4 stages associated with the leading role of the laboratory's heads: Prof. V.G. Shtefko (1924-1945), Prof. V.I. Puzik (1945-1974), Prof. O.A. Uvarova (1974-1980), and Prof. V.V. Yerokhin (1980 up to the present time). The laboratory's researches are the productive path of phthisiomorphology. The tasks of the laboratory have been associated with the problems to be solved by the institute. This applies the morphology, pathogenesis, classification of tuberculosis, and changes in inflammatory reactions in response to the altered Mycobacterium tuberculosis and to specific and pathogenetic actions on tuberculosis. New living conditions give the laboratory's researchers new tasks that require their solution at a new technological level.
