Microbiology

is the science in charge of the study and analysis of microorganisms, tiny living things not visible to the human eye, also known as microbes.

He is dedicated to studying organisms that are only visible through the microscope: prokaryotic and simple eukaryotic organisms.

Bacteriology (later a subdiscipline of microbiology) is considered founded by the botanist Ferdinand Cohn (1828-1898). Cohn was also the first to formulate a scheme for the taxonomic classification of bacteria.

He became famous for discovering the tuberculosis bacillus in (1882) (presents his findings on March 24, 1882) as well as the cholera bacillus in (1883) and for the development of Koch's postulates. He received the Nobel Prize in Medicine in 1905. He is considered the founder of bacteriology.

Bacteriology: Study of prokaryotes (bacteria, archaea). It also covers the study of mycobacteria (mycobacteriology).
Virology: Study of viruses.
Mycology: Study of fungi.
Protozoology: Study of protozoa.
Micropaleontology: Study of microfossils.
Palynology: Study of pollen and spores.
Phycology: Also called algology, it is the study of algae and microalgae.

Hooke discovered the cells by observing a cork slide under the microscope, realizing that it was made up of small polyhedral cavities that resembled the cells of a honeycomb.

Van Leeuwenhoek is credited with discoveries of protozoa, bacteria, the cell's vacuole, and, according to some experts, sperm, which he called "animalcules."

Louis Pasteur was a French chemist and bacteriologist born on December 27, 1822, with important contributions to science, especially in microbiology. His main contributions were: pasteurization, development of the vaccine, fermentation and the vaccine against rabies, among others.
