NewsHow bacteria in the mouth may offer new clues to cognitive dysfunction in people with schizophrenia
An association between oral microbiota and cognitive performance in schizophrenia has been reported by researchers. The study shows that lower oral microbial diversity is associated with poorer cognitive function, with specific predicted microbial metabolic pathways potentially linked to this relationship.

NewsHow genes influence the microbes in our mouths
A new study has found human genetic factors that influence the oral microbiome and may increase risk of cavities and tooth loss in some people. Analysis of the now largest collection of oral microbiome profiles reveals interactions between human and bacterial DNA.

NewsBreath carries clues to gut microbiome health
Researchers have shown that disease-associated bacteria in the gut can be detected through exhaled breath. They found that chemicals released by gut microbes and captured from the breath of children and mice can reveal the composition of the bacteria living in the intestines.

NewsOral bacterium may promote breast cancer development and spread
Researchers found that Fusobacterium nucleatum, an oral bacterium commonly associated with periodontal disease, can promote breast cancer initiation, tumor growth and spread by inducing DNA damage and altering cancer cell behavior.

NewsAltered microbiome: Oral bacteria play a role in chronic liver disease
A new study shows that identical bacterial strains occur in both the mouth and gut of patients with advanced chronic liver disease and also reveals a mechanism by which oral bacteria affect gut health. The researchers also found that this process coincides with worsening liver health.

NewsA new ally against tooth decay: Arginine offers sweet relief
A new human clinical trial finds arginine can prevent caries due to bacterial plaques by reducing the acidity, altering the plaque structure and reducing harmful bacteria in the plaques.

NewsGut bacteria changes at the earliest stages of inflammatory bowel disease
People newly diagnosed with the most common IBD subtypes, Crohn’s disease and ulcerative colitis, lose beneficial anaerobic bacteria that help with digestion of complex carbohydrates. Patients instead experience a rise in oxygen-tolerant bacteria from the mouth that travel in the gut.

NewsOral bacterium tied to disability severity in multiple sclerosis
A research team has conducted a study with findings that suggest a potential association between the relative abundance of Fusobacterium nucleatum (F. nucleatum), a bacterium found in the mouth, and disease severity in multiple sclerosis (MS) patients.

NewsCloves and miswak: Antimicrobial effects of Syzygium aromaticum and Salvadora persica against common pathogens in vitro
Clove essential oil (CEO) derived from Syzygium aromaticum and miswak (Salvadora persica) contains bioactive compounds with antimicrobial properties. This study aimed to evaluate the in vitro antimicrobial efficacy of CEO, miswak, and their combination against key peri-implantitis pathogens.

NewsDo oral bacteria from tooth infections worsen diabetes risk?
A new study demonstrates that Porphyromonas gingivalis and its lipopolysaccharide are potent drivers of both periapical bone destruction and systemic metabolic dysfunction, acting through an IL-17–dependent inflammatory pathway.

NewsFamily dogs boost adolescent mental health through the microbiome
It’s no surprise that dogs benefit people’s mental health. Researchers point to a reason as to why: dogs prompt changes in the collection of microbes that live in and on our bodies, resulting in an increase in mental health.

NewsHear us out: scientists say garlic shows promise as a mouthwash alternative
Garlic extract demonstrates antimicrobial efficacy comparable to other widely used antiseptics and disinfectants, such as chlorhexidine, according to scientists. While garlic-based mouthwash may cause more discomfort than chlorhexidine, it offers longer-lasting residual effects.

NewsTraces of bacteria inside brain tumors may affect tumor behavior
Scientists have uncovered unexpected traces of bacteria within brain tumors. This discovery offers new insights into the environment in which brain tumors grow and sets the stage for future studies seeking to improve treatment outcomes.

NewsSecrets of microbial motion: How bacteria swash, glide and shift gears to survive
Two new studies reveal surprising ways microbes move, with implications for human health and disease. The first shows that salmonella and E. coli can ’swash’ across moist surfaces even when their flagella are disabled, while the second probes the T9SS gearbox in flavobacteria.

NewsStudy links multiple sclerosis with distinct oral microbiome
Researchers have produced the most comprehensive genetic and metabolic analysis to date of the oral microbiome associated with multiple sclerosis (MS). They found that people with MS have a distinct oral microbiome compared to healthy individuals.

NewsResearchers partner on $28M initiative to build a precision phage platform for promoting public health
Researchers have embarked on a five-year initiative that aims to harness the natural predators of bacteria – known as phages – as precision tools to shape the human microbiome and promote health.

CareersSummer studentship: Amelia investigates how Streptococci aggregate with other oral bacteria
Amelia Rohim reports back on her AMI-sponsored summer studentship which focused on the investigation of inter-species aggregation between oral bacteria at the University of Michigan with Dr. Alexander Rickard.

NewsOral bacteria linked to Parkinson’s via the gut-brain axis
Researchers have identified the mechanism by which metabolites produced by oral bacteria in the gut may trigger the development of Parkinson’s disease.

NewsOral microbes linked to increased risk of pancreatic cancer
Twenty-seven species of bacteria and fungi among the hundreds that live in people’s mouths have been collectively tied to a 3.5 times greater risk of developing pancreatic cancer, a study shows.

NewsPlant-derived compound has antimicrobial and anti-inflammatory effects against periodontal disease
Morin-based powder, extracted from guava leaves, apple peel, and figs, can be slowly released with the help of polymers and serve as an alternative to antibiotics.
