This is a timeline of bacteriology, attempting to describe important events in the development of the field. For the treatment of bacterial diseases, visit Timeline of antibiotics.

Big picture

Time period Development summary
17th century Experimental explorations with microorganisms is already conducted in this century.[1]
18th century Botanists and zoologists try to structure and classify the world of the invisible living organisms.[1]
1854–1920 This period is known as the "golden age of microbiology", in which standardized microbiological techniques are developed and most of the disease-causing bacteria are discovered. Louis Pasteur and Robert Koch stand out as the great scientists in the field.[2] German physician Robert Koch introduces the science of microorganisms to the medical field, identifying bacteria as the cause of infectious diseases and process of fermentation in diseases. French Scientist Louis Pasteur develops techniques to produce vaccines.
1940s The genetics of bacteriophages begin to be studied vigorously, after the development of techniques for the study of bacteriophage infection in single bacteria.[3]
1990s The first bacterium genome is sequenced.[4]


Full timeline

Year Event type Details Geographical location
2 billion BC A bacterium becomes symbiotic with the cell from which animals and plants later develop. Chromosomes from this bacterium’s mitochondria would later carry 37 genes in the human body.[5]
220 million BC Bacteria and single-celled animals and plants from this period become encased in tree resin on the northern edge of the Tethys Ocean. Scientists in 2006 study the organisms in amber of this time from a town in the Italian Dolomites. Ciliates and amoeba in the amber appear identical to modern examples.[5]
