A microbiologist is a scientist who studies organisms called microbes. Microbes can take the form of bacteria, viruses, or fungi. The microbiologist is trained to study these microbes in depth. He or she must be familiar with the microbes' environments, how they live, and the effect they have on the world around them.

As microbes are diverse, microbiologists tend to have their own specific area of study. often focused on a specific type of microbe. Microbiologists who study only bacteria are called bacteriologists. Those who study viruses are known as virologists.

One of the main research aims of the microbiologist is to find out how microbes affect the world around them. Certain types of microbes are harmful to humans, and a microbiologist may study the reasons for this, along with ways to prevent infection in humans. An immunologist studies how the body defends itself against certain microbes.

Throughout history, many fatal diseases have been eradicated thanks to the help of the microbiologist. By learning how microbes exist, reproduce, and attack humans, it is easier to stop them. Many microbes are capable of causing new diseases, as the environment is constantly changing. Epidemiologists are trained to study outbreaks of disease and to determine their causes and how they can be prevented in the future.

The microbiologist is mainly based in the laboratory, where he or she may work in many specialized areas. Microbiologists can be concerned with medicine, healthcare, or the food industry. Other areas of study include agriculture and healthcare. The military also employs microbiologists. Biological warfare development and defense is a controversial field employed by many governments around the world.

The day-to-day work of the microbiologist is often varied. A wide variety of tests are used when researching microbes. As well as testing pure culture samples, the microbiologist must also work with highly sophisticated computer software when undertaking research. This software is used to track the development of the microbes. It is also used to calculate and theorize on the growth and development of specific microbes in the environment.

Microbiology is a very important branch of science. The microbiologist tests the food that we eat and makes the medicine we take when ill. Microbiologists help prevent nations from being wiped out by disease and make sure that washing powder is safe for human skin. It takes years of dedicated training to become a microbiologist, and up to date research and learning are essential. Governments spend billions of dollars each year to ensure that their vital microbiology divisions are second to none.
