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

  • Mosquito-borne viruses linked to stroke
    on September 18, 2020 at 2:42 pm

    A deadly combination of two mosquito-borne viruses may be a trigger for stroke, new research has found.

  • New high-speed test shows how antibiotics combine...
    on September 17, 2020 at 10:12 pm

    Researchers have developed a new method to determine - rapidly, easily and cheaply - how effective two antibiotics combined can be in stopping bacterial growth. The new method is simple for laboratories to use and can provide greater scope for customizing treatment of bacterial infections.

  • Engineered bacteria churn out cancer biomarkers
    on September 17, 2020 at 2:54 pm

    Pity the glycan. A lab has created these very tools by commandeering simple, single-celled microorganisms - namely E. coli bacteria - and engineering them to explore the complex process of glycosylation and the functional role that protein-linked glycans play in health and disease.

  • Discovery of microbes with mixed membranes sheds...
    on September 17, 2020 at 2:53 pm

    Current research suggests that more complex life-forms, including humans, evolved from a symbiosis event between bacteria and another single-celled organism known as archaea. However, evidence of a transition period in which the two organisms mixed where nowhere to be found. That is, until now. In the deep waters of the Black Sea, a team of scientists found microbes that can make membrane lipids of unexpected origin.

  • Researchers discover how worms pass down...
    on September 17, 2020 at 12:45 pm

    Researchers have discovered that the microscopic roundworm Caenorhabditis elegans recognizes a small RNA made by a pathogenic bacterium, and uses that RNA to convey learned avoidance of the bacterium to offspring.

    on September 18, 2020 at 7:26 am

    A small study by Canadian veterinary science experts being presented at this ESCMID Conference on Coronavirus Disease (ECCVID, held online from 23-25 September) suggests that a substantial proportion of pet cats and dogs can be infected by SARS-CoV-2 by their owners. Furthermore, in several cases pets found to be infected had COVID-19-like respiratory symptoms at the time their owner had COVID-19.

    on September 17, 2020 at 12:30 pm

    In the ongoing fight against COVID-19, experts on microbiology and copper are recommending an expanded use of the metal to reduce the virus's spread. So might copper be incorporated into the construction of masks, the universally accepted virus-fighting personal item?

  • Research on risk of metal contamination in...
    on September 17, 2020 at 12:00 pm

    New research by University of Alberta scientists on the risks for metal contamination at an inactive mining site in northwestern Saskatchewan could help inform a strategy for a safe long-term reclamation of the site.

  • Possible genetic link found between...
    on September 15, 2020 at 2:55 pm

    A genetic mutation might be the reason dogs with hypothyroidism are less likely to develop T-zone lymphoma (TZL). That's the finding from Morris Animal Foundation-funded researchers at Colorado State University who tried to identify genetic risk factors for TZL using a genome-wide association study (GWAS) and subsequent targeted sequencing. They recently published their results in the journal BMC Genomics.

  • Researchers create new tool for controlling genes...
    on September 14, 2020 at 1:46 pm

    University of Arkansas researchers have developed an efficient tool for controlling genes in methanogens, a finding that could advance research in fields as diverse as climate change and biofuel production.
