What is the study of microorganisms called?

The study of microorganisms is called microbiology. This branch of science focuses specifically on the various types of microorganisms, including bacteria, viruses, fungi, and protozoa, along with their interactions with humans, animals, plants, and the environment. Microbiologists study the characteristics, behaviors, and effects of these organisms, which can be crucial for various fields such as medicine, agriculture, and environmental science.

In contrast, biochemistry deals with the chemical processes and substances that occur within living organisms, while immunology focuses on the immune system and how it protects against pathogens. Pathology, on the other hand, involves the study of diseases, their causes, and their effects on the body, but it does not specifically center on microorganisms themselves. Understanding microbiology is essential for many roles in healthcare and laboratory settings, particularly in controlling infections and ensuring sterile environments.
