Streptococcus gordonii News and Research

RSS

The Streptococcus gordonii organism is a commensal member of the human oral flora. It initiates the formation of biofilms on tooth surfaces known as dental plaque, which is strongly associated with the development of dental cavities (caries) and gum disease. It is a frequent causative agent of bacterial endocarditis (inflammation of the membrane lining the heart) which often occurs as a result of oral trauma, allowing S. gordonii to invade the bloodstream and colonize the heart.

Oral bacteria interaction leads to smelly breath

Having bad breath really stinks! Now, researchers from Japan report that a particular combination of bacteria in our mouths may be responsible for producing some very unpleasant smells.

What role does human microbiota play in COVID-19 severity?

In a recent study published in the journal Advanced Science, researchers explored the dynamic changes in the respiratory tract and gut microbiota in coronavirus disease 2019 (COVID-19) patients. They observed and analyzed these changes during different disease progression stages among patients with differential disease severities.

Microbiome 'profiling' may help identify people at risk of long COVID

The make-up of the gut microbiome may be linked to a person's risk of developing 'long COVID' many months after initial infection with SARS-CoV-2, the virus responsible for COVID-19 infection, suggests research published online in the journal Gut.

Study reveals potentially key molecular process that occurs in infective endocarditis

The human mouth can harbour more than 700 different species of bacteria. Under normal circumstances these microbes co-exist with us as part of our resident oral microbiota.

UofL researcher receives patent for novel biochemical discovery

University of Louisville researchers are a step closer to eliminating periodontal disease through their work to develop synthetic molecules that prevent a bacteria responsible for the disease from spreading throughout the mouth.

S. gordonii may trigger infective endocarditis

Oral bacteria that escape into the bloodstream are able to cause blood clots and trigger life-threatening endocarditis. Further research could lead to new drugs to tackle infective heart disease, say scientists presenting their work at the Society for General Microbiology's Spring Conference in Dublin this week.

Discovery of two proteins may lead to more effective treatment of endocarditis and infections associated with implants

A research team at the Faculty of Odontology at Malmö University in Sweden has discovered two new proteins that are of importance to the survival of bacteria and their colonization of the human body. Besides enhancing our knowledge of the ability of bacteria to spread, the findings may also lead to more effective treatment of endocarditis and infections associated with implants.
