microorganism : an organism (such as a bacterium or protozoan) of microscopic or ultramicroscopic size — Webster
Microorganism, or microbe is a microscopic organism, which may be single-celled or multicellular. The study of microorganisms is called microbiology, a subject that began with the discovery of microorganisms in the 1670s by Antonie van Leeuwenhoek. Robert Hooke coined the term “cell” after viewing plant cells under his microscope. Later, in the 19th century, Louis Pasteur found that microorganisms caused food spoilage, debunking the theory of spontaneous generation. In 1876 Robert Koch discovered that microorganisms cause diseases.
Microorganisms are very diverse and include all bacteria, archaea and most protozoa. This group also contains some fungi, algae, and some micro-animals such as rotifers. Many macroscopic animals and plants have microscopic juvenile stages. Some microbiologists classify viruses and viroids as microorganisms, but others consider these as nonliving. — Wikipedia

Scientists discern new antibiotics resistance...
on March 20, 2018 at 6:13 pm
In a recent study, a group of scientists reveals both the widespread distribution and broad-spectrum resistance potential of D-stereospecific peptidases, providing a potential early indicator of antibiotic resistance to non-ribosomal peptide antibiotics. […]
Continuously killing bacteria on coated stainless...
on March 20, 2018 at 12:44 pm
Stainless steel is the gold standard for kitchen appliances and cookware, but bacteria can grow on these surfaces, contaminating food. Current coatings available on the market are pricey and potentially harmful, so scientists have now developed an affordable specialized polymer coating for such surfaces that they can recharge with bleach treatments. […]
Tiny gels sop up intestinal toxins
on March 20, 2018 at 12:43 pm
Bacterial infections that target the intestine can cause conditions that range from uncomfortable to deadly. While it's easy to blame the bacteria, it's actually the toxins the bacteria produce that trigger inflammation, diarrhea, fever and cramps. Researchers now report the development of a microgel scavenger that targets toxins instead of bacteria. […]
Natural sniper kills hospital bacterium
on March 20, 2018 at 12:41 pm
Bacteria produce proteins to take out specific competitors. One of these proteins can kill the hospital bacterium Pseudomonas aeruginosa. Microbial geneticists have unraveled how this protein launches its attack and ensures that the bacteria die very quickly. In the long term, these proteins hold potential for new antibiotic cocktails. […]
Making intricate images with bacterial communities
on March 19, 2018 at 11:00 pm
A technique for growing sticky films of bacteria into elaborate microscopic images could reveal how potentially dangerous biofilms grow and transmit antibiotic resistance, and could lead to novel biomaterials or synthetic microbial communities. […]
