Treponema denticola is a Gram-negative, obligate anaerobic, motile and highly proteolytic spirochete bacterium. It is one of four species of oral spirochetes to be reliably cultured, the others being Treponema pectinovorum, Treponema socranskii and Treponema vincentii [ 2 ] .
Chronic periodontitis is initiated by Gram-negative tooth-associated microbial biofilms that elicit a host response, which results in bone and soft tissue destruction. In response to endotoxin derived from periodontal pathogens, several osteoclast-related mediators target the destruction of alveolar bone and supporting connective tissue such as the periodontal ligament.
If improperly treated necrotizing may become chronic and/or recurrent. In developed countries, necrotizing gingivitis occurs mostly in young adults with predisposing factors such as psychological stress, sleep deprivation, poor oral hygiene, smoking, immunosuppression and/or malnutrition. In developing countries, necrotizing gingivitis occurs ...
Periodontal disease typically arises from the development of plaque biofilm, which harbors harmful bacteria such as Porphyromonas gingivalis and Treponema denticola. These bacteria infect the gum tissue surrounding the teeth, leading to inflammation and, if left untreated, progressive damage to the teeth and gum tissue. [9]
Periodontal pathogens are bacteria that have been shown to significantly contribute to periodontitis.. Dental plaque, the precursor of periodontal disease, is a complex biofilm consisting mainly of bacteria, but also archaea, protozoa, fungi and viruses.
Necrotizing periodontal diseases are caused by a mixed bacterial infection that includes anaerobes such as P. intermedia [1] and Fusobacterium as well as spirochetes, such as Treponema. [3] Necrotizing gingivitis may also be associated with diseases in which the immune system is compromised, including HIV/AIDS. [1]
RSV vaccine side effects in older adults . The CDC lists the following as possible side effects of the RSV vaccine: Pain, redness, and swelling where the shot is given. Fatigue. Fever. Headache ...
Treponema is a genus of spiral-shaped bacteria. The major treponeme species of human pathogens is Treponema pallidum, whose subspecies are responsible for diseases such as syphilis, bejel, and yaws. Treponema carateum is the cause of pinta. [2] Treponema paraluiscuniculi is associated with syphilis in rabbits. [3]
