Microbiologists are scientists who study microorganisms, which are tiny living organisms that can only be seen under a microscope. These include bacteria, viruses, fungi, and protozoa. Their work helps us understand how these organisms affect our health, the environment, and various industries, such as food production and pharmaceuticals. In laboratories, microbiologists conduct experiments to identify and classify microorganisms, investigate their properties, and explore their roles in disease and ecology. They may also develop new methods for controlling harmful microbes or harnessing beneficial ones, contributing to advancements in medicine, agriculture, and biotechnology.
