Selenomonas noxia
Selenomonas noxia
Selenomonas noxia (pronunciation: se-le-no-mo-nas nox-ia) is a species of bacteria that belongs to the genus Selenomonas, within the family Veillonellaceae. It is a gram-negative, anaerobic, rod-shaped bacterium that is primarily associated with human oral infections, particularly periodontal disease.
Etymology
The name Selenomonas noxia is derived from the Greek words selene (moon) and monas (unit), referring to the crescent shape of the bacterium. The species epithet noxia is Latin for harmful, indicating its pathogenic nature.
Characteristics
Selenomonas noxia is a motile bacterium, possessing a single polar flagellum. It is a fermentative bacterium, capable of metabolizing a variety of carbohydrates to produce lactic acid and other byproducts. It is also known for its ability to adhere to oral surfaces, forming biofilms that contribute to the development of periodontal disease.
Pathogenicity
Selenomonas noxia is considered a pathogenic bacterium due to its association with periodontal disease. It is often found in high numbers in the oral cavity of individuals with periodontitis, suggesting a role in the disease's progression. The bacterium's ability to form biofilms on oral surfaces also contributes to its pathogenicity.
Treatment
Treatment for infections caused by Selenomonas noxia typically involves the use of antibiotics, such as metronidazole or amoxicillin. Regular oral hygiene practices, including brushing and flossing, can also help to control the growth of this bacterium.
