[Methodologic basis for studying the morphology of infectious processes].

The present survey emphasizes the need for further study of pathological anatomy of infectious diseases. Particular attention should be given to the dynamics of development and causes of morphological alterations. Such investigations aimed at shedding a new light on the pathogenesis of infectious diseases, should elucidate biological properties of the causative agent and special features of reactive processes occuring in the diseased organism. They must be multi-disciplinary in character and include the efforts of physicians, microbiologists and other experts. Some investigations are critically surveyed, some methodological problems are discussed.
