Undergraduate Study
The department offers undergraduate study for the bachelor of science degree with a major in microbiology. For the curriculum in microbiology, see Agriculture, Curricula. In this department, principal emphasis is placed on understanding microorganisms and their interrelationships with other organisms in nature, the application of microbiology in medicine, agriculture and industry, and the study of fundamental life processes as exemplified by microorganisms. The department of microbiology also participates in an interdepartmental undergraduate minor in emerging globaldiseases (see the department of entomology for details). Some fields of microbiology, especially advanced research, may require further training. Undergraduate work in the department is designed to provide sound preparation for graduate study, training for bachelors-level employment, and admission to professional programs such as medicine, veterinary medicine and dentistry.

Graduates of the Department of Microbiology are able to recognize and appreciate the diversity and complexity of microbial life represented by procaryotes, eucaryotes, and viruses. In addition to understanding fundamental principles of microbial growth, physiology, genetics, biochemistry, and ecology, the program emphasizes the impact that the microbial world has on human, animal and plant health, as well as on industry and biotechnology. Graduates are able to design and implement experimental approaches to address specific questions. In addition, graduates are able to communicate scientifically, using a variety of media.

Graduate microbiologists find career opportunities in a wide variety of areas: in hospital and clinical laboratories; in federal, state, and local government agencies; in research and development; in dairy and food processing; in the pharmaceutical and fermentation industries.
Undergraduate programs for the major in microbiology usually include the following basic courses: 302, 310, 402, 404, 430, 440, 450 and labs. Aspects of these courses emphasize communication skills, environmental issues, problem solving, and laboratory techniques. Courses in the following areas are required as supporting work: biology, chemistry, biochemistry, genetics, mathematics and physics.

Preveterinary preparation may be accomplished through the curriculum major in this department (see College of Veterinary Medicine, Admission Requirements).
Students majoring in microbiology are eligible to apply for the Cooperative Education Program with the Agricultural Research Service. If selected, the student will obtain full-time, paid, work experience at either the National Animal Disease Center, the National Veterinary Services Laboratory, or the Soil Tilth Laboratory in Ames. Other internship opportunities also are available.

The department offers a minor in microbiology which may be earned by accumulating a minimum of 15 credits from the departmental offerings.

Majors in microbiology must take courses in written communication (Engl 104, 105; and one of 302, 309 or 314), one course in oral communication (Sp Cm 212), and must meet the College of Agriculture English proficiency requirement of C or better in these courses. Students must also meet the College of Agriculture requirements for credit in courses in ethics, and the university diversity and multicultural requirements.

Graduate Study
The department offers the degrees master of science and doctor of philosophy, and a doctoral minor to students majoring in other departments.

Graduates in the Microbiology program have a strong broad-based general knowledge of as well as advanced knowledge in a specific aspect of microbiology. Those students completing a thesis have the technical research, critical thinking, problem solving, and computer skills to design, implement, and conduct research using a variety of modern molecular tools and equipment. They are able to communicate research results effectively with scientific peer groups in both oral and written formats.

Prerequisite to graduate study is completion of coursework in general microbiology, biology, biochemistry, mathematical sciences, and physics.

The faculty also participates in the interdepartmental majors and programs in genetics, immunobiology, MCDB (molecular, cellular, and developmental biology), neuroscience, technology and social change, toxicology, and water resources (see Index).
Each graduate student must demonstrate proficiency in English composition within two semesters in residence.

Courses open for nonmajor graduate credit: 310, 330, 374, 406, 419, 420, 421, and 485.
