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

  • Flu and heart disease: The surprising connection...
    on October 15, 2021 at 10:42 pm

    Patients who have cardiovascular disease are at increased risk of serious complications from the flu, according to a new study. The study found that not only are traditional flu-related outcomes worse among some patients with CVD, but infection in those patients also is associated with an increased risk of cardiovascular events. Getting the influenza vaccine, however, substantially reduces cardiovascular risks.

    on October 15, 2021 at 5:32 pm

    Bacteria can store extra resources for the lean times. It's a bit like keeping a piggy bank or carrying a backup battery pack. One important reserve is known as cyanophycin granules, which were first noticed by an Italian scientist about 150 years ago. He saw big, dark splotches in the cells of the blue-green algae (cyanobacteria) he was studying without understanding either what they were or their purpose. Since then, scientists have realized that cyanophycin was made of a natural green […]

    A new study found that the environmental lifestyle that bacteria possess reveal why some go rogue and turn deadly while others remain harmless to humans. The findings focus on Vibrio vulnificus, better known as the flesh-eating bacteria. However, what the scientists found could help create a model that may well extend to other human pathogens.

    An international research team led by Professor Stephanie Grond from the Institute of Organic Chemistry at the University of Tübingen has found that the natural substance collinolactone reduces artificially-induced stress on nerve cells, protecting them from the kind of damage that occurs in neurodegenerative diseases. Collinolactone is isolated from soil bacteria, and its chemical structure is identical to that of rhizolutin, which was isolated from bacteria on the roots of the Asian […]

    Technology created at the University of South Florida (USF) could be the key to safely reusing disposable face masks. Researchers have figured out a way to rapidly disinfect and electrostatically recharge N95 respirators, recovering their original filtration efficiency and protection capability against COVID-19 and other airborne diseases.
