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

  • Human fetal lungs harbor a microbiome signature
    on January 17, 2020 at 5:39 pm

    The lungs and placentas of fetuses in the womb -- as young as 11 weeks after conception -- already show a bacterial microbiome signature, which suggests that bacteria may colonize the lungs well before birth. This first-time finding deepens the mystery of how the microbes or microbial products reach those organs before birth and what role they play in normal lung and immune system development.

    It is an awkward idea, but a couple's ability to have kids may partly depend on who else is present. The reproductive tracts of males and females contain whole communities of micro-organisms. These microbes can have considerable impact on (animal) fertility and reproduction. They may even lead to new species.

    on January 17, 2020 at 1:08 pm

    Sanitary care in ants to fight disease is known to improve the wellbeing of the colony, yet it has been unclear how social disease defense interferes with pathogen competition inside the individual host body. Biologists now revealed that collective care-giving has the power to bias the outcome of coinfections in fungus-exposed colony members.

  • Mosquitoes engineered to repel dengue virus
    on January 16, 2020 at 7:17 pm

    Scientists have synthetically engineered mosquitoes that halt the transmission of the dengue virus. Biologists developed a human antibody for dengue suppression in Aedes aegypti mosquitoes, the insects that spread dengue. The development marks the first engineered approach in mosquitoes that targets the four known types of dengue, improving upon previous designs that addressed single strains.

    World population growth and lifestyle are the main causes of the increase in the volume of wastewater. As a result of the treatment of these waters, millions of tons of sewage sludge are generated, filling landfills and generating pollution, unpleasant odors, and public health risks. To combat these issues, one of the most important alternatives is to transform sewage sludge, which has a high organic-matter content, into a resource that can be used for agricultural purposes as a crop fertilizer.
