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

  • Something old, something new in the ocean's blue
    on November 13, 2019 at 8:30 pm

    Microbiologists have discovered a new metabolic process in the ocean. Ranging from molecular structures of individual genes and detection of their global distribution, their results give insight into the pathway process and its degradation products and thus provide valuable information for future calculations of the ocean`s carbon dioxide balance.

  • Chitin-binding proteins override host plant's...
    on November 13, 2019 at 5:48 pm

    A recent article studies chitin-binding proteins from a soilborne fungus (Verticillium nonalfalfae) that causes vascular wilt in plants. This fungus binds a particular protein (VnaChtBP) to chitin in order to abolish the host plant's chitin-triggered burst of reactive oxygen species and shield the fungus from being digested by the plant.

  • 'Give me the calcium!' Tulane virus takes over...
    on November 13, 2019 at 4:19 pm

    Researchers uncover the first piece of functional evidence suggesting that Tulane virus and human norovirus use viroporins to control cellular calcium signaling.

  • Insulin can increase mosquitoes' immunity to West...
    on November 13, 2019 at 3:18 pm

    A discovery has the potential to inhibit the spread of West Nile virus as well as Zika and dengue viruses. The researchers demonstrated that mammalian insulin activated an antiviral immunity pathway in mosquitoes, increasing the insects' ability to suppress the viruses. Since mosquito bites are the most common way humans are infected with West Nile, stopping the virus among the insects would protect human health.

    on November 12, 2019 at 7:29 pm

    Scientists have revealed how common respiratory bugs that cause serious infections in people with cystic fibrosis interact together, according to a new study.

    on November 14, 2019 at 4:00 pm

    In an effort to reverse the decline in the health of the world's oceans, the United Nations (UN) has declared 2021 to 2030 to be the Decade of Ocean Science for Sustainable Development. One key requirement for the scientific initiative is data on existing global ocean conditions. An important trove of data is already available thanks to the Tara Oceans expedition, an international, interdisciplinary enterprise that collected 35,000 samples from all the world's oceans between 2009 and 2013. The […]

    on November 14, 2019 at 1:43 pm

    An unexpected discovery about fertilization from the University of Virginia School of Medicine reveals new insights on how sperm and egg fuse and could have major implications for couples battling infertility—and may lead to a future male contraceptive.

  • Something old, something new in the ocean's blue
    on November 13, 2019 at 6:01 pm

    Charles Darwin suspected something in the "clear blue water" of the ocean that was even smaller than the protozoa he could see under the microscope. "Today we know that every liter of ocean water is swarming with hundreds of millions of microorganisms," explains marine researcher Rudolf Amann, Director at the Max Planck Institute for Marine Microbiology in Bremen. His colleague Tobias Erb from the sister institute of terrestrial Microbiology in Marburg adds: "Although only micrometers in size, […]

    on November 13, 2019 at 5:16 pm

    Some gastrointestinal viruses need calcium. They need calcium ions to carry out several essential aspects of viral life, such as entry into host cells, genome replication and building new viruses to invade other cells. The cells invaded by viruses also use calcium. They use it as signals to regulate many of the cells' own processes, but viruses can takeover cellular calcium signaling to satisfy their own needs.

  • Unknown virus discovered in humans
    on November 13, 2019 at 12:29 pm

    An international team based in Austria has unearthed a previously unknown type of virus in samples of human bodily fluids. The researchers were looking for viruses that infect bacteria, known as bacteriophages, with an emphasis on those that attack the Escherichia coli (E. coli) bacterium found in the human gut. The team identified a total of 43 bacteriophages in samples of human bodily fluids, particularly in blood samples. The discovery of such phages in the human body is especially […]
