"Microbiology is the scientific study of microorganisms, those being of unicellular (single-celled), multicellular (consisting of complex cells), or acellular (lacking cells)." - "Microbiology (from Ancient Greek μῑκρος (mīkros) 'small', βίος (bíos) 'life', and -λογία (-logía) 'study of') is the scientific study of microorganisms..."

"Microbiology encompasses numerous sub-disciplines including virology, bacteriology, protistology, mycology, immunology, and parasitology."
"Eukaryotic microorganisms possess membrane-bound organelles and include fungi and protists, whereas prokaryotic organisms—all of which are microorganisms—are conventionally classified as lacking membrane-bound organelles and include Bacteria and Archaea."
"Microbiologists traditionally relied on culture, staining, and microscopy for the isolation and identification of microorganisms."
"However, less than 1% of the microorganisms present in common environments can be cultured in isolation using current means."
"With the emergence of biotechnology, Microbiologists currently rely on molecular biology tools such as DNA sequence-based identification, for example, the 16S rRNA gene sequence used for bacterial identification."
"Viruses have been variably classified as organisms, as they have been considered either as very simple microorganisms or very complex molecules."
"Prions, never considered as microorganisms, have been investigated by virologists, however, as the clinical effects traced to them were originally presumed due to chronic viral infections, virologists took a search—discovering 'infectious proteins'."
"The existence of microorganisms was predicted many centuries before they were first observed, for example by the Jains in India and by Marcus Terentius Varro in ancient Rome."
"The first recorded microscope observation was of the fruiting bodies of molds, by Robert Hooke in 1666."
"But the Jesuit priest Athanasius Kircher was likely the first to see microbes, which he mentioned observing in milk and putrid material."
"Antonie van Leeuwenhoek is considered a father of microbiology as he observed and experimented with microscopic organisms in the 1670s."
"Scientific microbiology developed in the 19th century through the work of Louis Pasteur."
"In medical microbiology, Robert Koch made significant contributions."
"'μῑκρος' (mīkros)" translates to "small" in Ancient Greek, as used in the term "microbiology."
"Virology is one of the sub-disciplines of microbiology that focuses on the study of viruses."
"Prokaryotic organisms—all of which are microorganisms—are conventionally classified as lacking membrane-bound organelles and include Bacteria and Archaea."
"Microbiologists rely on molecular biology tools such as DNA sequence-based identification, for example, the 16S rRNA gene sequence used for bacterial identification."
