microorganism : an organism (such as a bacterium or protozoan) of microscopic or ultramicroscopic size — Webster See also OneLook
Microorganism, or microbe, is a microscopic organism, which may be single-celled or multicellular. Microorganisms include all unicellular organisms and so are extremely diverse. Of the three domains of life identified by Carl Woese, all of the Archaea and Bacteria are microorganisms. These were previously grouped together in the two domain system as Prokaryotes, the other being the Eukaryotes. The third domain Eukaryota includes all multicellular organisms and many unicellular protists and protozoans. Some protists are related to animals and some to green plants. Many of the multicellular organisms are microscopic, namely micro-animals, some fungi and some algae, but these are not discussed here. They live in almost every habitat from the poles to the equator, deserts, geysers, rocks and the deep sea. Some are adapted to extremes such as very hot or very cold conditions, others to high pressure and a few such as Deinococcus radiodurans to high radiation environments. Microorganisms also make up the microbiota found in and on all multicellular organisms. — Wikipedia

Microbiology is the scientific study of microorganisms, those being unicellular (single cell), multicellular (cell colony), or acellular (lacking cells). 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. However, less than 1% of the microorganisms present in common environments can be cultured in isolation using current means. Microbiologists often rely on molecular biology tools such as DNA sequence based identification, for example the 16S rRNA gene sequence used for bacteria identification. — Wikipedia

Antibiotic resistance is a global health threat. In 2019 alone, an estimated 1.3 million deaths were attributed to antibiotic resistant bacterial infections worldwide. Looking to contribute a solution to this growing problem, researchers at Baylor College of Medicine have been studying the process that drives antibiotic resistance at the molecular level.

Microorganisms are important contributors to the deep-sea sulfur cycle. However, in-situ detection of deep-sea microorganisms faces great challenges due to the extreme complexity of the deep-sea environment, the difficulty of sampling, isolation and cultivation of microorganisms, and the lack of near real-time nondestructive monitoring methods for microbial sulfur metabolism.

In medical research and diagnostics, the microbiome, i.e. the microbial colonization of the intestine, is increasingly gaining attention. A stool sample can be used to precisely analyze the complex microbial ecosystem of the gut. There are basically two methods for this: traditional cultivation on plates with specific culture media or the quite expensive DNA analysis of the stool sample.

A subset of white blood cells, known as myeloid cells, can harbor HIV in people who have been virally suppressed for years on antiretroviral therapy, according to findings from a small study supported by the National Institutes of Health.

Life comes in all shapes in sizes, but some sizes are more popular than others, new research has found. A survey of body sizes of all Earth's living organisms has uncovered an unexpected pattern. Contrary to what current theories can explain, our planet's biomass -- the material that makes up all living organisms -- is concentrated in organisms at either end of the size spectrum.
