Acad. Stephan Angeloff The foundation of the Institute of Microbiology realized the necessity for a formation of a research center with national importance, which to carry out contemporary investigations in rapidly developing and prosperous branches of microbiological science. The initial period in the development of the Institute (1947 - 1962) was connected with the studies of the actual after the Second World War infectious pathology of domestic animals and humans. The achievements in the study of the etiology and the development of diagnostic methods and immunoprophylactic preparations for different infections were significant. Investigations in the field of infectious immunology was set by Prof. Vladimir Markov, Member of BAS. Industrial microbiology started with the studies of Prof. Ignat Emanuilov, Member of BAS, on the microbiology of milk and dairy products, biochemistry and physiology of lactic acid bacteria and the application of bacterial enzymes (proteinases) in cheesemaking. Along with bacteria as producers of biologically active substances filamentous fungi were investigated. In the field of microbial morphology since 1964 electron microscope studies of bacteria, filamentous fungi, yeasts and cells of the immune system of the macroorganism were performed. The investigations in the field of microbial biochemistry after 1973 aimed the elucidation at modern biochemical level of the main peculiarities in the physiology and biosynthetic capabilities of the microbial cells: various enzymes, proteinase and nuclease inhibitors, microbiological transformation of steroids, protein-lipid interactions in bacterial membrane. Systemic investigations carried out by Prof. Simeon Galabov and his collaborators on the relationship between antigenic structure and biological properties of bacterial endotoxins resulting in development of diagnostic kits and vaccines, as well as data on interferon-inducing activity. The research work in the field of microbial genetics was connected with the problem of prophage interference, genetic transfer in Bacillus thuringiensis and Streptococci from group A, hybridization of Actinomyces sp. in order to increase their productivity, construction of gene maps of Streptomycetes - producers of antibiotics, molecular identification of microorganisms by the use of PCR, as well as genomic differentiation by M13 DNA fingerprinting and ribotyping. The Institute of Microbiology has always played a leading role in applied microbiology. Microbial producers of a wide spectrum of biologically active substances were isolated: enzymes, aminoacids proteins, carotinoids, and various antibiotics with different spectrum of activity were isolated. Physiology and biochemistry of microbial producers, including extremophilic bacteria as well as the properties of the synthesized products were studied. A wide spectrum of methods for immobilization of enzymes and microbial cells, producers of biologically active substances, were elaborated. The investigations in infectious bacteriology after 1962 were pointed on the changes provoked in the pathogen during the course of infectious and immunizatory process. Later, studies were focused on the factors and mechanisms of bacterial virulence and bacteriahost interactions. At the beginning of 60th years started investigations in the field of the experimental chemotherapy of viral infections. Systemic studies on the creation and characterization of some new effective antivirals, on the combined effects of viral inhibitors and their mechanisms of action. Iinvestigations on cell immunity and L-forms of bacteria and a widespectrum immunopharmacological screening was performed aiming the selection of new active substances. MISSION The Stephan Angeloff Institute of Microbiology, Bulgarian Academy of Sciences (BAS) is national research center in microbiological sciences. It is one of the leading institutes in the field of microbiology for South-Eastern Europe. By its wide research area the Institute is unique among the other institutes from the Pasteur family. The institute is recognized in Europe and worldwide for its modern research tendencies. Ever since its foundation 60 years ago, the Institute’s strategic lines have been: (1) investigations on problems implicated in public health and biotechnology; (2) teaching activities and training of PhD students. In 2004 the Institute of microbiology was associated with Institut Pasteur, Paris and a member of the International Network of Pasteur Institutes (INPI). This is a great recognition of the activities of our institute by this world centre of microbiology and molecular biology, a leader in the struggle against infectious diseases.
