The work records of professor Mihai Ciucă (found in the archives of the Department of Microbiology) give us an insight into his scientific thoughts and practical activity. These documents speak of his dedication to the problem of the bacteriophage started in Jules Bordet's laboratory of the Pasteur Institute in Brussels, in 1920 and continued until 1969, the year in which he died. Since the discovery of the phenomenon of lysogeny, called the Bordet-Ciucă phenomenon, the professor initiated a wide range of research themes on the bacteriophage, guiding and promoting the work of a great number of specialists in the National Center, founded in 1949.
