ABSTRACT
In 1884, V.Ya. Danilewsky, a professor of Kharkov University, published a small article ‘About Blood Parasites (Haematozoa)’ in the Russian Medicine journal which marked a qualitatively new stage in the development of protozoology. V.Ya. Danilewsky validated the main concepts of his doctrine about the comparative parasitology of the blood in a series of papers published between 1884 and 1896 in Russian, French, and German journals, making a contribution to the solution of some fundamental problems of general biology and medicine, and primarily the problem of malaria. †
