Inside of biology, microbiology is the discipline that deals with study of microbes or microorganisms.
It should be noted that these organisms are plausible to be observed only through the microscope. Because microbes are microscopic living organisms, that is, very small, which may be made up of a cell (unicellular), or, failing that, by minimal cellular aggregates without cellular differentiation. Meanwhile, within the latter we find eukaryotes (cells plus nucleus, such is the case of fungi) and prokaryotes (cell but without a nucleus, such as bacteria).
Microbiology is a discipline that, due to its object of study, is constantly making new discoveries and advancing in the subject. Even according to some estimates from it, only a very small percentage of the microbes on earth are known, 1%. This situation tells us that despite technological advances and the development of science, the field of study is so broad that it still has a long way to go.
As a consequence, his study is especially focused on those microorganisms that are pathogenic for humans, it is that he works side by side with specialties of medicine such as: epidemiology, pathology and immunology.
Although it is a reality that many microorganisms are linked to the development of diseases in humans, it is also worth mentioning that there are also many microorganisms that are essential for life on the planet, because simply without them it would be impossible for the human species to continue alive .
Throughout history, many scientists have contributed to the knowledge and research of the matter, including Christian Gottfried Ehrenberg, who first applied the concept of bacteria, Ferdinand Julius Cohn, who made impressive contributions to bacteriology and of course Louis Pasteur who would develop methods to preserve food for longer using microorganisms.
