Selenomonas noxia

Selenomonas noxia is a species of bacteria in the genus Selenomonas, which is part of the family Veillonellaceae. It is a Gram-negative, anaerobic, non-spore-forming, and motile bacterium. Selenomonas noxia is primarily found in the human oral cavity, where it is associated with periodontal disease.

Characteristics

Selenomonas noxia is a Gram-negative bacterium, meaning it does not retain the crystal violet stain used in the Gram stain procedure. Instead, it takes up the counterstain (safranin or fuchsine) and appears red or pink under a microscope.

As an anaerobic bacterium, Selenomonas noxia does not require oxygen for growth. It can survive and grow in environments where oxygen is absent.

Selenomonas noxia is non-spore-forming, which means it does not produce spores. Spores are a form of dormant stage that some bacteria enter to survive in unfavorable conditions.

The bacterium is motile, meaning it can move independently using various mechanisms, such as flagella, cilia, or pseudopodia.

Habitat and Pathogenicity

Selenomonas noxia is primarily found in the human oral cavity. It is one of the many species of bacteria that make up the oral microbiota. The bacterium is associated with periodontal disease, a serious gum infection that damages the soft tissue and destroys the bone that supports your teeth.
