What is the job of a Microbiologist?



The microbiologist is a scientist who studies living microorganisms (viruses, bacteria, fungi, etc.). He can practice in multiple sectors of activity. Observation and research are at the heart of the microbiologist’s job.

In addition, a microbiologist is a doctor who, using a conventional or electron microscope, studies microbiological processes.

In microbiology, there are several branches namely bacteriology, mycology, phycology, parasitology, virology, etc.

The microbiologist analyzes the functioning of living organisms of microscopic size and also studies their interactions with the environment.

He often specializes in one area.

Bacteriologist or virologist seeks to identify bacteria or viruses causing diseases. It also isolates the micro-organisms already identified to reduce their harmful effects and participates in the development of vaccines and antibiotics.
