B.S. in Microbiology
Find new ways to prevent and treat infectious diseases to improve our understanding of one health — the interconnected health of plants, people, animals and the environment.
A bachelor’s degree in microbiology prepares you to apply systems thinking and develop solutions to protect our planet, its plant life, and its human and other inhabitants from microbial threats. This major is ideal for students pursuing careers in scientific research, medicine and veterinary care.
Why Major in Microbiology?
As a Microbiology student, you’ll join the front lines of exploring and protecting the world, while gaining a fundamental understanding of microbes and their vital importance to our everyday lives, including the plants we grow and the food we eat.
Students who major in microbiology may choose to specialize in medical microbiology, food safety, and consumer health, plant pathology and microbiology, environmental microbiology, and microbial genomics.
A degree in microbiology prepares you for careers in disease prevention and treatment. It also can serve as a springboard for graduate school. According to the U.S. Bureau of Labor Statistics, the median pay for careers related to microbiology was $85,470 per year with a faster-than-average job growth overall (2023).
There are a variety of career opportunities available to students who earn a degree in microbiology, including:
- Microbiologist: Provide expert knowledge on pathogenic and beneficial microbes for government agencies, universities, agricultural companies, food safety organizations, research institutes and international agencies.
- Researcher or research assistant: Work in the public or private sectors to advance insight, medicines, and technologies related to emerging diseases, environmental health, food safety, population health, and bioterrorism.
- Plant pathologist: Explore the critical role that disease-causing microbes, including viruses, bacteria, fungi and nematodes, play in limiting crop production.
- Clinical Microbiologist: help medical professionals diagnose, prevent and cure diseases with a focus on understanding immune systems, viruses and bacteria.
- Industrial technician: Engineer organisms and communities to optimize and improve the production of food, pharmaceuticals, fuels and many other products on a commercial scale.
- Food safety and consumer health specialist: Study the close relationship between microbes and agricultural crops and food products, and how those microbes inhabit and contaminate food.
As a microbiology student, you’ll study the power of microorganisms and the role they play in plant, human and animal health. Courses required to complete a bachelor’s degree in microbiology are subject to change, so remember to meet with your advisor regularly to review your course plan.
Microbiology students have the unique opportunity to gain fundamental and practical experience in the classroom, lab and field with courses like the following:
- Pathogenic Bacteriology: Examine key mechanisms of bacterial pathogenesis through human and veterinary pathogens.
- One Health Microbial Perspective: Use case studies to understand connections between human, animal, and environmental health.
- Antibiotics–A Biological Perspective: Explore antibiotic and anti-infective research by identifying major classes, modes of action, antibiotic resistance, biosynthesis, and industrial production of antibiotics.
- Microbial Genetics: Covers prokaryotic gene structure and function, gene transfer, DNA processes, with hands-on DNA sequence analysis, gene cloning strategies, and gene expression regulation.
- Microbial Diversity: Discover the genetic, species, phylogenetic, functional, and ecological diversity of prokaryotic and eukaryotic microorganisms.
- Environmental Microbiology: Gain a foundational understanding of environmental microbiology, covering pollutant interactions, microbial biogeochemistry, bioremediation, and recent discoveries like bacteriophage roles and ‘missing links’ in the tree of life.
- General Mycology: Explores fungal diversity, biology, and roles as pathogens, saprobes, and symbionts, with insights into fungi as eukaryotic research models and their industrial applications.
Accelerated M.S. in Microbiology
In your junior year at the University of Arizona, you may apply for admission to the accelerated master’s degree program in microbiology. This allows you to receive dual credit toward your bachelor’s and master’s degrees for selected courses completed during your senior year of undergraduate studies. The accelerated program allows you to complete your master's degree within one year of receiving your bachelor’s degree.
Applicants must meet certain academic standards, have adequate experience in the research laboratory of a microbiology faculty member who chooses to sponsor them, and complete a formal thesis project.
