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. 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
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

Imagine a technology that could target pesticides to treat specific spots deep within the soil, making them more effective at controlling infestations while limiting their toxicity to the environment. Researchers have taken a step toward that goal. They discovered that a particular plant virus can deliver pesticide molecules deeper below the ground, targeting places normally beyond their reach.

Researchers document impact of coffee on bowels
on May 19, 2019 at 4:35 pm
Coffee drinkers know that coffee helps keep the bowels moving, but researchers in Texas are trying to find out exactly why this is true, and it doesn't seem to be about the caffeine, according to a new study. Researchers, feeding rats coffee and also mixing it with gut bacteria in petri dishes, found that coffee suppressed bacteria and increased muscle motility, regardless of caffeine content. […]

on May 17, 2019 at 7:06 pm
Gastric cancer, Q fever, Legionnaires' disease, whooping cough—though the infectious bacteria that cause these dangerous diseases are each different, they all utilize the same molecular machinery to infect human cells. Bacteria use this machinery, called a Type IV secretion system (T4SS), to inject toxic molecules into cells and also to spread genes for antibiotic resistance to fellow bacteria. Now, researchers at Caltech have revealed the 3-D molecular architecture of the T4SS from the […]
