Novel mechanism by which “good” bacteria colonize the gut discovered

The microbes that inhabit the gut are critical for human health, and understanding the factors that encourage the growth of beneficial bacterial species — known as "good" bacteria — in the gut may enable medical interventions that promote gut and overall human health.

What role does dysbiosis play in Parkinson's disease?

The current study, published in the journal Revue Neurologique, is based on the hypothesis that dysbiosis, or unhealthy variations in the gut and oral microbiota, is a key component of PD pathogenesis.

Gut microbiomes and mental health: how do they interact?

A new study published in the journal Frontiers in Medicine reviewed recent literature on the link between gut microbiota, the brain, and neurological disorders.

Bacteria require phase separation to thrive in the mammalian gut

The common commensal gut bacterium Bacteroides thetaiotaomicron uses phase separation of the transcription termination factor Rho to colonize and thrive in the mammalian gut, according to a new study in mice.

Study suggests a novel strategy to combat multidrug-resistant S. pneumoniae infections

Pneumococcal disease leads to over three million hospitalizations and hundreds of thousands of deaths annually.

Study implicates gut microbiome and immune response in hospital-acquired infections

In a recent study published in the journal Nature Medicine, researchers at the University of Calgary analyzed the dynamics of fecal microbiota and conducted single-cell profiling of inflammatory responses and systemic immunity to determine associations between gut microbiome dysbiosis and an increased risk of nosocomial infections.

Purine metabolite xanthine may play a role in Th17 cell differentiation in the gut

The gut is home to a cast of microbes that influence health and disease. Some types of microorganisms are thought to contribute to the development of inflammatory conditions, such as inflammatory bowel disease (IBD), but the exact cascade of events that leads from microbes to immune cells to disease remains mysterious.

New biomimetic model helps study wound healing in burn and laceration wounds

Burn wounds are notoriously prone to bacterial infection and typically lead to a larger amount of scar tissue than laceration wounds.

Reversing infertility in sterile mice by reducing high-circulating cholesterol with a bacterial protein

Houston Methodist scientists reversed infertility in sterile mice by reducing high-circulating cholesterol with a bacterial protein, showing further evidence that links high cholesterol to female infertility.

Age and sex determine the effects of microbiota on mice's metabolome

The gut handles all ingested foods for further digestion and assimilation. In addition, it harbors a wealth of microbes that produce metabolic byproducts with multiple effects on host physiology. Therefore, changes in the gut microbiome's composition can shift the gut's metabolome as well.

Long-term antibiotic therapy for adolescent acne can affect liver metabolism and promote adiposity

A growing body of evidence is showing that the healthy gut microbiome – a community of microorganisms that live together in the gut – influences many aspects of human growth and development, especially during adolescence.
