The Department of Immunology and Medical Microbiology offers programs leading to the Master of -Science and Doctor of Philosophy degrees in the medical sciences, with specialization in immunology and microbiology. Specific areas of specialization include infectious diseases, cellular and humoral immunity, immuno- chemistry, molecular genetics, parasitology, dental microbiology, and bacterial and animal virology. The undergraduate preparation for graduate study should be wide in scope and should include general biology, physics, chemistry (two to three years, including organic and physical chemistry), and preferably statistics, calculus, genetics, and bacteriology. A bachelor's degree in bacteriology or microbiology is not required. In graduate school the student will at first obtain a general background in microbiology as preparation for research and teaching. The remaining course work should be arranged according to the student's interests and com- petence. Through individual planning of course work, research, and teaching, the graduate student is offered an educational atmosphere to help him develop certain skills and gain intellectual independence and initiative.
