What is a microbiologist?
Quick Answer
A microbiologist is a scientist who studies microorganisms such as bacteria, viruses, fungi, and protozoa. They work in medicine, food safety, ecology, and biotechnology.
The Full Story
Microbiologists investigate microscopic life and the ways it interacts with humans, animals, plants, and environments. Some study disease-causing microbes in hospitals and public health labs, while others focus on fermentation, soil ecology, ocean microbes, or industrial uses of bacteria and fungi. The field became especially important after the work of scientists such as Louis Pasteur and Robert Koch in the 19th century. Modern microbiology combines microscopy, culture methods, and DNA sequencing.
