Why is it important to study microorganisms?

Microbes are vitally important to all life on Earth. As versatile organisms, they play a major role in various biochemical processes such as biodegradation, biodeterioration, climate change, food spoilage, epidemiology and biotechnology.

How do you study microorganisms?

The principal way a microbiologist studies microorganisms is by observing them through a microscope. A microscope is a device that enlarges objects using a process called magnification. The simplest form of a microscope is a magnifying glass consisting of a single lens.

Virologists study viruses that affect humans, animals, insects, bacteria, fungi and plants, in community, clinical, agricultural and natural environments.

Why do biologist study viruses?

By studying viruses, we can learn about the biology of host cells and organisms, develop strategies against viral disease and manipulate viruses for our own purposes. Some viruses are only a single self-replicating gene, while others can encode almost a thousand proteins and be the size of a bacterium.

Is a virologist a biologist?

Virologists are medical doctors that oversee the diagnosis, management and prevention of infection. They’re also scientists, who may drive research on various aspects of viruses. A virologist may be both a scientist and a physician.
