Encyclopedia

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. A December 2017 report stated that 3.45-billion-year-old Australian rocks once contained microorganisms, the earliest direct evidence of life on Earth. — Wikipedia

Science

Microbiology is the study of microorganisms, those being unicellular (single cell), multicellular (cell colony), or acellular (lacking cells). Microbiology encompasses numerous sub-disciplines including virology, parasitology, mycology and bacteriology.

Eukaryotic microorganisms possess membrane-bound cell organelles and include fungi and protists, whereas prokaryotic organisms—all of which are microorganisms—are conventionally classified as lacking membrane-bound organelles and include eubacteria and archaebacteria. 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 16s rRNA gene sequence used for bacteria identification. — Wikipedia

  • Shedding light on darker parts of our genetic...
    on July 19, 2019 at 2:21 pm

    More than half of our genome consists of transposons, DNA sequences that are reminiscent of ancient, extinct viruses. Transposons are normally silenced by a process known as DNA methylation, but their activation can lead to serious diseases. Very little is known about transposons but researchers in an international collaboration project have now succeeded for the first time in studying what happens when DNA methylation is lost in human cells. These findings provide new insight into […]

  • Waking up sleeping bacteria to fight infections
    on July 18, 2019 at 3:25 pm

    Researchers have identified a mechanism of how sleepy bacteria wake up. This finding is important, as sleepy cells are often responsible for the stubbornness of chronic infections. Findings reveal new perspectives on how to treat chronic infections, for example by forcing bacteria to wake up. […]

    on July 18, 2019 at 3:24 pm

    Scientists have confirmed that viruses can kill marine algae called diatoms and that diatom die-offs near the ocean surface may provide nutrients and organic matter for recycling by other algae, according to a new study. […]

    on July 18, 2019 at 3:24 pm

    Researchers have identified how differences in the genetic sequence of the two main strains of the cancer-associated Epstein-Barr virus (EBV) can alter the way the virus behaves when it infects white blood cells. […]

  • Waking up sleeping bacteria to fight infections
    on July 18, 2019 at 5:29 pm

    Researchers in the group of Jan Michiels (VIB-KU Leuven Center for Microbiology) identified a mechanism of how sleepy bacteria wake up. This finding is important, as sleepy cells are often responsible for the stubbornness of chronic infections. Findings published in Molecular Cell reveal new perspectives on how to treat chronic infections, for example by forcing bacteria to wake up. […]

  • Plant viruses may be reshaping our world
    on July 17, 2019 at 6:29 pm

    The community of viruses is staggeringly vast. Occupying every conceivable biological niche, from searing undersea vents to frigid tundra, these enigmatic invaders, hovering between inert matter and life, circumnavigate the globe in the hundreds of trillions. They are the most abundant life forms on earth. […]

    on July 17, 2019 at 6:00 pm

    Skin tests that can distinguish between cattle that are infected with tuberculosis (TB) and those that have been vaccinated against the disease have been created by an international team of scientists. The traditional TB tuberculin skin test shows a positive result for cows that have the disease as well as those that have been vaccinated against the disease. By distinguishing between these two groups, the new tests will facilitate the implementation of vaccination programs that could […]

    on July 17, 2019 at 5:24 pm

    It's a case of grand larceny that could lead to new fuels and cleanup chemicals. Ten species of red algae stole about 1 percent of their genes from bacteria to cope with toxic metals and salt stress in hot springs, according to a study in the journal eLife. […]
