Encyclopedia

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

    A major route toward creating effective vaccines against dengue virus and Zika involves the E protein that covers the surface of each viral particle. But creating such a vaccine has proven difficult for a number of reasons. Now researchers have delineated the details of one major barrier to a promising vaccine. It's something we all have -- a natural body temperature of about 98.6 degrees. […]
