The programme comprises the two complementary fields of cell biology and virology, covering a wide range of interactions between cellular structures and intracellular pathogens (viruses, viroids, mycoplasmas, rickettsiae, chlamydiae). The Instruction takes place in the specialised laboratories of cell biology and virology, microbiology and biochemistry at NBU and also at other scientific and medical units to provide an extensive study of eukaryotic and prokaryotic pathogens, host cells and tumour cells. The students get familiar with biological processes and phenomena at the organismal, tissue, cellular, subcellular and molecular levels using modern physicochemical, biochemical, biophysical, genetic, microbiological, virological and physiological methods, thus mastering their up-to-date interdisciplinary molecular biology knowledge. They focus on cell biology, biochemistry, genetics, molecular genetics, microbiology, virology, molecular virology, molecular immunology, biophysics, plant physiology, animal and human physiology, necessary and crucial for solving current problems such as the control and treatment of dangerous viral infections and cancers.
