Streptococcus viridians

Description and Significance

Describe the appearance, habitat, etc. of the organism, and why you think it is important.

Appearance:Chained cocci. Catalase negative and gram positive bacteria Habitat: mucosal membranes such as the oral cavity and the gastrointestinal tract.

Etc.: Very similar genetic sequence to S. pneumonniae.

Importance: Those who are infected by S. viridians, may become resistant to antibiotics such as penicillin and drugs for cystic fibrosis.

Genome Structure

Describe the size and content of the genome. How many chromosomes? Circular or linear? Other interesting features? What is known about its sequence?

Cell Structure, Metabolism and Life Cycle

Interesting features of cell structure; how it gains energy; what important molecules it produces.

Ecology and Pathogenesis

Habitat; symbiosis; biogeochemical significance; contributions to environment.

If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
