Treponema denticola is a motile and highly proteolytic bacterium. The Gram-negative oral spirochete is associated with the incidence and severity of human periodontal disease. Treponema denticola levels in the mouth are elevated in patients with periodontal diseases and the species is considered one of the main etiological agents of periodontitis.
It seems that chewing gum is not a new trend! Researchers have found chewing gum that is 5,700 years old and it has provided clues regarding ancient DNA. A study with the findings was published in the journal Nature Communications. It is titled, “A 5,700-year-old human genome and oral microbiome from chewed birch pitch.”
The bacteria that cause periodontitis, a disease affecting the tissues surrounding the teeth, seems to play a part also in the onset of pancreatic cancer, say the researchers at the University of Helsinki and the Helsinki University Hospital, Finland, and the Karolinska Institutet, Sweden.
Today at the 45th Annual Meeting & Exhibition of the American Association for Dental Research, researcher Jeffrey Ebersole, University of Kentucky, Lexington, USA, will present a study titled "Systemic Antibody Responses to Oral Bacteria with Aging." The AADR Annual Meeting is being held in conjunction with the 40th Annual Meeting of the Canadian Association for Dental Research.
Much of what we know about Oetzi - for example what he looked like or that he suffered from lactose intolerance - stems from a tiny bone sample which allowed the decoding of his genetic make-up.
A University of Florida study shows that the same bacteria that cause gum disease also promotes heart disease - a discovery that could change the way heart disease is diagnosed and treated. Researchers report their findings today at the annual meeting of the American Society for Microbiology.
A drug currently used to treat intestinal worms could protect people from periodontitis, an advanced gum disease, which untreated can erode the structures-including bone-that hold the teeth in the jaw. The research was published ahead of print in Antimicrobial Agents and Chemotherapy.
A mineral found at health food stores could be the key to developing a new line of antibiotics for bacteria that commonly cause diarrhea, tooth decay and, in some severe cases, death.
Researchers report this week that older adults who have higher proportions of four periodontal-disease-causing bacteria inhabiting their mouths also tend to have thicker carotid arteries, a strong predictor of stroke and heart attack.
Three centuries after a pioneering Dutch microbiologist first observed the spiral-shaped oral pathogen Treponema denticola, scientists have deciphered the bacterium’s entire DNA sequence and used comparative genomics to cast new light on other spirochete microbes.
