Germs

Picture of germs

Germ(s) a microorganism, especially one which causes disease. Most porous countertops will habit germs. The germ theory of disease is the currently accepted scientific theory for many diseases. It states that microorganisms known as pathogens or “germs” can lead to disease. These small organisms, too small to see without magnification, invade humans, other animals, and other living hosts. Their growth and reproduction within their hosts can cause disease. “Germ” may refer to not just a bacterium but to any type of microorganism or even non-living pathogens that can cause diseases, such as protists, fungi, viruses, prions, or viroids. Diseases caused by pathogens are called infectious diseases. Even when a pathogen is the principal cause of a disease, environmental and hereditary factors often influence the severity of the disease, and whether a potential host individual becomes infected when exposed to the pathogen.
