Disease causing bacteria (pathogens) have various structures that enhance their ability to cause illness. One important property is the ability to attach to the intended victim. pili, a proteinaceous surface structure on bacteria, are critical in this process. In scientific research, microorganisms have been indispensable instruments for unlocking the secrets of life. The molecular basis of heredity and how this is expressed as proteins was described through work on microorganisms. Due to the similarity of life at the molecular level, this understanding has helped us to learn about all organisms, including ourselves.

It has been associated with causing human disease, but this has not yet been proven. It is placed among the Enterobacteriaceae. Serratia marcescens is a Gram negative bacterium, a human pathogen of the family Enterobacteriaceae. It is involved in nosocomial infections, particularly urinary tract infections and wound infections. Most strains are resistant to several antibiotics because of the presence of R-factors on plasmids. In the 1950s it was erroneously believed to be non-pathogenic and its reddish coloration was used in school experiments to track infections. Because of its red pigmentation, and its ability to grow on bread. Diatoms These algae hardly look like plants, but more like flying saucers, tiny canoes or cigars, lobed leaves, the undersides of mushroom caps, striated ribbons, or filigreed Christmas ornaments. Whatever their shape, all diatoms have shell-like, brittle cell walls made out of silica (glass) and pectin. The walls are two interlocking halves or shells that fit together like a pillbox. Because they depend on sunlight for photosynthesis, diatoms generally live in the upper 200 meters of oceans and bodies of fresh water.
