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

  • To survive asteroid impact, algae learned to hunt
    on October 30, 2020 at 6:21 pm

    Tiny, seemingly harmless ocean plants survived the darkness of the asteroid strike that killed the dinosaurs by learning a ghoulish behavior -- eating other living creatures.

  • High-sugar diet can damage the gut, intensifying...
    on October 29, 2020 at 6:20 pm

    Mice fed diets high in sugar developed worse colitis, a type of inflammatory bowel disease (IBD), and researchers examining their large intestines found more of the bacteria that can damage the gut's protective mucus layer.

  • Face mask aims to deactivate virus to protect...
    on October 29, 2020 at 6:20 pm

    Researchers have developed a face mask with an embedded antiviral layer that sanitizes the wearer's respiratory droplets to make them less infectious to others.

  • How the immune system deals with the gut's...
    on October 29, 2020 at 3:58 pm

    New research suggests that our immune system may play an active role in shaping the digestive-tract flora, which is tightly linked to health and disease.

  • Learning the language of sugars
    on October 28, 2020 at 5:40 pm

    We're told not to eat too much sugar, but in reality, all of our cells are covered in sugar molecules called glycans. Glycans regulate many important processes including infection by bacteria and viruses, but little is known about them because their structures are highly complex. A team has now created a new suite of deep learning and bioinformatics tools that enable the comprehensive study of glycan sequences, providing insights into their functions and improving our understanding of […]

    on October 30, 2020 at 4:10 am

    Decaying jellyfish blooms fuel the rapid growth of just a few strains of seawater bacteria, effectively keeping this organic material within the water column food web, reveals a new study published in Frontiers in Microbiology. This research furthers our understanding of how marine ecosystems are impacted by jellyfish blooms, which have been observed to be happening on a more frequent basis.

    on October 28, 2020 at 3:00 pm

    A team of infectious disease researchers has developed a new method to identify virulence genes in Streptococcus pneumoniae, the leading cause of bacterial pneumonia. Using this technique in a mouse model of pneumonia, they were able to gain new insights into the progression of the disease and its interaction with the flu virus.

    Corals that appear healthy are more prone to getting sick when they're home to too many parasitic bacteria, new research at Oregon State University shows.

  • The sweet spot of flagellar assembly
    on October 27, 2020 at 3:36 pm

    To build the machinery that enables bacteria to swim, over 50 proteins have to be assembled according to a logical and well-defined order to form the flagellum, the cellular equivalent of an offshore engine of a boat. To be functional, the flagellum is assembled piece by piece, ending with the helix called flagellar filament, composed of six different subunits called flagellins. Microbiologists from the University of Geneva (UNIGE) have demonstrated that adding sugar to the flagellins is […]

  • Scientists uncover prophage defense mechanisms...
    on October 27, 2020 at 3:35 pm

    A phage is a virus that invades a bacterial cell. While harmless to human cells, phages are potentially deadly to bacteria since many phages enter a cell in order to hijack its machinery in order to reproduce itself, thus destroying the cell.
