The study of the great variety of living organisms that are too small for us to see without a microscope-the microbes or microorganisms. It is emerging as the key biological science. It has become an umbrella term that encompasses many disciplines of study including the study of bacteria (Bacteriology), the study of fungi (Mycology), the study of parasites (Parasitology), the study of viruses (Virology). Also this area is concerned with the physiology, biochemistry, mocecular biology, ecology, biotechnology. Microorganisms provide the models used in molecular biology for research. This research at the molecular level has provided, and continues to provide, the answers to numerous fundamental questions in quality control and assessment of food and pharmaceutical products, genetics, metabolism and cell forms and functions. The department of Microbiology started its journey from the inception of Victory Nursing College as a core subject. The department offers a four-year Bachelor of Science (Honors’) [B.Sc. (Hon’s.)] program in Microbiology at the undergraduate level under the University of Rajshahi. The course aims to give the basic and detailed knowledge and understanding of important aspects of microbiology as currently applied in food, health and medical sciences ad industry, in the environment management, in biotechnology as well as in basic and primary research. We are dedicated to provide the quality education, through both teaching and research, necessary to meet the needs of this growing field.
