NewsDepression linked to a less diverse oral microbiome
A study found that people with less diversity in their oral microbiomes were more likely to have symptoms of depression. Smoking, drinking, and dental care also influenced the relationship between the oral microbiome and depression.

NewsMicrobial proteins reveal chemical signatures of body sites and inflammation
A new study shows that protein sequences associated with microbial communities in the human gut have uniquely low stoichiometric water content and undergo counterintuitive chemical shifts toward chemically reduced states during inflammation.

NewsStudy links oral microbiome diversity with long sleep duration in teenagers and young adults
A new study to be presented at the SLEEP 2025 annual meeting found that oral microbiome diversity is positively associated with long sleep duration among teenagers and young adults.

NewsOral microbiota transmission partially mediates depression and anxiety in newlywed couples
Given that bacterial transmission can occur between spouses, a new study aimed to investigate whether the transmission of oral microbiota between newlywed couples mediates symptoms of depression and anxiety.

NewsMicrobial pioneers: how bacteria shape dental implant health from day one
A new study suggests that the earliest microbes to colonize a dental implant may determine its long-term fate. Using high-resolution genomic sequencing and a 12-week clinical timeline, scientists tracked how microbial ecosystems form around new dental implants.

NewsHeart rhythm disorder traced to bacterium lurking in our gums
A new study finds that a gum disease bacterium can slip into the bloodstream and infiltrate the heart. There, it drives scar tissue buildup—known as fibrosis—distorting the heart’s architecture, interfering with electrical signals, and raising the risk of atrial fibrillation (AFib).

NewsBad breath, bad news: how gum disease could worsen liver conditions
A review discusses the close association of oral health and liver diseases, since oral pathogens and their factors can translocate to liver through the gastrointestinal tract and exacerbate chronic liver conditions in multiple ways, as supported by animal and clinical studies.

NewsPoor oral health linked with body pain and migraines in women
A study showed that oral health, affected by the oral microbiome, has a direct link to musculoskeletal pain, including chronic migraines and headaches, as experienced by women with fibromyalgia.

NewsOral microbiota offer promise as screening tool for young children with autism spectrum disorder (ASD)
Scientists have found promising connections between oral microbiota and autism spectrum disorder (ASD). Their study introduces a prediction model with an 81% accuracy rate for identifying children with autism through simple oral sampling.

NewsStudy reveals how dextran sulfate sodium-induced colitis exacerbates periodontitis
A new study provides strong evidence that the NOX2/ROS axis plays a key role in the exacerbation of periodontitis in the presence of colitis.

NewsThroat microbiome holds clues to older Australians’ health
A simple swab from the back of the throat, known as the oropharynx, may offer clues about health challenges faced by aged care residents.
-
NewsMouth bacteria may hold insight into your future brain function
A study revealed that the types of bacteria in our mouths may have direct impacts to brain health, which would link mental illness, such as Alzheimer’s disease or dementia.
-
NewsJuicing may harm your health in just three days
Juicing without fibres turns out to be detrimental to both gut and oral microbiomes by disrupting their compositions, leading to the flourishing of harmful bacteria associated with inflammation.

NewsNIH awards $20.6 million grant to establish Human Virome Characterization Center at UCLA
NIH has awarded a $20.6 million grant over five years to establish one of five Human Virome Characterization Centers to advance understanding of the virome’s role in human health and disease across the oral-gut-brain axis.

NewsA common mouth and gut bacterium may be linked with increased stroke risk
A common bacterium usually found in the mouth and gastrointestinal tract, Streptococcus anginosis, may be abundant in the guts of people with stroke and is associated with a worse prognosis and increased risk of death, according to a preliminary study.

NewsOral microbiome may affect cognitive function as we age
The microbial ecosystems within our mouths may affect our cognitive function as we age, according to a study. Interventions such as prebiotics, including dietary nitrate, have potential for delaying cognitive decline.
-
NewsOral cancer and microbiome: new insights into tumor growth mechanisms
A recent study has made significant strides in uncovering how the oral microbiome plays a crucial role in the progression of oral squamous cell carcinoma (OSCC), unveiling metabolic pathways and mechanisms that may serve as potential therapeutic targets.

NewsWorried about a pregnant woman’s stress and mental health? Her saliva may hold the key.
New research has found that the number and type of microbes present in the saliva of pregnant women differ according to whether they are experiencing life stress and symptoms of anxiety, depression and post-traumatic stress disorder.
