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

    Microbes living in the rectum could make a difference to the effectiveness of experimental HIV vaccines, according to researchers.

  • Deadly 'superbugs' destroyed by molecular drills
    on December 12, 2019 at 7:27 pm

    Motorized molecules activated by light target and drill through highly antibiotic resistant bacteria and kill them within minutes. The molecules can open bacteria to attack by drugs they previously resisted. The strategy could be applied to bacterial infections or diseases on the skin, in the lungs or in the gastrointestinal tract.

  • Novel study underscores microbial individuality
    on December 12, 2019 at 4:44 pm

    A single drop of seawater can contain a wide representation of ocean microbes from around the world—revealing novel insights into the ecology, evolution and biotechnology potential of the global microbiome. A new publication in Cell reports a staggering degree of biological diversity that defies contemporary definitions of microbial species, illuminates reasons behind challenges in metagenomic studies, and may even further understanding of how marine microbes respond to climate change.

    on December 11, 2019 at 8:59 pm

    In the last decade, scientists have made tremendous progress in understanding that groups of bacteria and viruses that naturally coexist throughout the human body play an important role in some vital functions like digestion, metabolism and even fighting off diseases. But understanding just how they do it remains a question.

    on December 10, 2019 at 6:38 pm

    Researchers at the University of São Paulo (USP) in Brazil have described a system present in a species of opportunistic bacterium found in hospital environments that injects a cocktail of toxins into competing bacteria and completely eliminates them. This discovery can be used in the future development of new antimicrobial compounds.

    A deadly superbug that infects an estimated 54,500 Americans a year has a secret weapon, a protein, that allows it to defy antibiotic treatment and immune system attacks. However, the secret is out now that researchers at The University of Texas Health Science Center at Houston (UTHealth) have identified the protein that acts as a defense mechanism for vancomycin-resistant enterococci (VRE). Their discovery opens the door for future treatment options in the fight against antibiotic resistance.
