理学学士学位（BSc）是三年制本科学位，使每个学生都可以发展自己在理科（理科专业）和相关科目的兴趣。学生可以灵活地将其主修科目与其他科学科目以及该大学其他学科的科目相结合。<br>微生物学是对微观尺寸的各种生物的研究，包括病毒，细菌，真菌，藻类，蠕虫和原生动物。微生物学是一门涉及微生物研究的科学，包括其在环境中的分布和作用以及它们与其他活生物体（包括人类（健康和疾病）和其他动物）的关系。对微生物的基本性质和分子结构的了解已成为分子生物学作为一门科学学科的发展以及建立微生物遗传学作为一门先进科学的主要因素。
Microorganisms are everywhere in our bodies, our food, the air, soil, and water. Because theyre everywhere, theyre involved in almost every aspect of our lives.<br>They are used in producing foods such as cheese, wine, and beer, as well as many pharmaceutical, chemical and agricultural products. They are important for soil fertility and the decomposition of materials but can cause major diseases in humans, animals and plants.<br>The harmful effects of some microorganisms link microbiology with immunology. Immunologists investigate how we can protect humans and animals from infectious diseases by using vaccines, and the role of the immune system in non-infectious diseases such as cancer.<br>An Otago graduate of Microbiology and Immunology will be limited only by their imagination.<br>Recent developments in fields such as biotechnology, aquaculture, molecular biology, microbial genetics, immunology and medicine have increased the demand for graduates with a microbiology and immunology major. The range of job opportunities continues to expand. Along with the traditional areas of teaching and research, graduates work in medical or veterinary laboratories and biotechnological and agricultural industries. Graduates are also employed as managers and advisers in government agencies.
