Microbiology is the science in charge of the study and analysis of microorganisms, tiny living beings not visible to the human eye also known as microbes. He is dedicated to studying organisms that are only visible through the microscope: prokaryotic organisms and simple eukaryotes. All microscopic living beings are considered microbes, these can be constituted by a single cell (unicellular), as well as small cell aggregates formed by equivalent cells (without cell differentiation); these can be eukaryotes (cells that possess nuclear envelope) such as fungi and protists; and prokaryotes (cells without nuclear envelope) such as bacteria. However, traditional microbiology has especially dealt with pathogenic microorganisms between bacteria, viruses and fungi, leaving other microorganisms in the hands of parasitology and other categories of biology.
