NewsMyocardial infarction may be an infectious disease
A pioneering study has demonstrated for the first time that myocardial infarction may be an infectious disease. This discovery challenges the conventional understanding of the pathogenesis of myocardial infarction and opens new avenues for treatment.

NewsMouth to gut bacteria migration explains why smoking is good for inflamed bowels
Researchers have discovered why smoking tobacco helps people suffering from ulcerative colitis. The study shows that smoking produces metabolites that encourage bacteria from the mouth to grow in the large intestines where they trigger an immune response.

NewsEarly challenges to the immune system disrupt oral health
Researchers identified changes over time in the oral microbiome of children living with HIV, offering insights into how early immune challenges shape not only oral health but also systemic health.

NewsMaple compound offers new way to fight tooth decay
A new study highlights the potential of using a natural compound from maple to combat the bacteria responsible for tooth decay: Streptococcus mutans. Epicatechin gallate is a powerful and safe alternative to traditional plaque-fighting agents.

NewsBeetroot juice lowers blood pressure in older people by changing oral microbiome
The blood pressure lowering effect of nitrate-rich beetroot juice in older people may be due to specific changes in their oral microbiome, according to the largest study of its kind.

NewsYour microbiome, your medicine: Scientists gather in Valencia to redefine the future of health
The International Society of Microbiota (ISM) will host the 12th World Congress on Targeting Microbiota, presenting groundbreaking research that positions the human microbiome as a central determinant of health and disease across multiple organ systems.

NewsVersion 4 update to Human Oral Microbiome Database includes expanded whole-genome sequence info
A recent update to the Human Oral Microbiome Database (HOMD) database includes a greatly expanded set of whole-genome sequences, reflecting a significant advancement in taxonomy of bacterial species and the study of microbial states in disease and health.

NewsWorld’s first AI system for single-tooth prediction of early childhood caries detection with over 90% accuracy
Scientists have developed the world’s first artificial intelligence (AI) system capable of predicting early childhood caries risk for individual teeth based on microbial characteristics, achieving an accuracy rate of over 90%.

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.
