Dysbiosis News and Research

RSS

Dysbiosis is a condition caused by an imbalance in the bacterial community (microbiome) of the human gut. Dysbiosis disrupts the ecoystsem of the gut, resulting in symptoms such as diarrhea, constipation, bloating, and indigestion, among others.

Microbes on the tongue could be used to diagnose pancreatic cancer

Researchers have found that disruption in the microbial composition of the tongue coating could serve as a biomarker for early-stage pancreatic cancer.

Metagenomic analysis helps understand role of bacterial species in Crohn's disease

Research on gut metagenome of patients with Crohn's disease elucidates how it influences the taxonomic and functional composition of intestinal microbiota.

Higher vitamin C intake crucial for metabolic syndrome patients to halt cycle of antioxidant disruption

A higher intake of vitamin C is crucial for metabolic syndrome patients trying to halt a potentially deadly cycle of antioxidant disruption and health-related problems, an Oregon State University researcher says.

New bacterial species may help fight obesity and metabolic disorders

The MyNewGut project has discovered new bacterial species and strains in healthy people that seem to be effective against obesity, metabolic and mental disorders related to stress and obesity (e.g. depression).

Live probiotics can change existing gut flora and alter immune response

New research published in the International Journal of Pharmaceutics demonstrates that 'good' bacteria in the live probiotic SymproveTM can successfully reach and colonize the gut, where they go on to change the existing gut flora. They are also capable of modifying immune response.

Immunity connects gut microbiota and age-related pathologies

EPFL scientists have discovered how a dysfunction in the immune system can cause an overload of a gut bacterium. The bacterium produces excess lactic acid, which in turn triggers the production of reactive oxygen species that cause damage to cells and many age-related pathologies.

Study uncovers link between gut disruption and aging

A new study has shed light on how the disruption of commensal bacteria within the gut can affect the immune system and lead to age-related pathologies.

Dietary restriction could help prevent age-related decline in integrity of human gut

Flies eating a Spartan diet are protected from leaky gut and the systemic inflammation associated with it as they age. Conversely, flies on a rich Atkins-like diet are more prone to developing intestinal permeability, a condition linked to a variety of human conditions including inflammatory bowel disease.

Study finds link between refined soluble fibers, gut microbiota and liver cancer

Many of the processed foods we find on grocery store shelves have been loaded up with highly refined soluble fibers such as inulin, a popular probiotic that recently received approval from the Food and Drug Administration to be marketed as health-promoting.

Microbiota in the intestines and cell stress cause colon cancer

"With our study we originally wanted to study the role of bacteria in the intestines in the development of intestinal inflammation," explains Professor Dirk Haller from the Department of Nutrition and Immunology at the Weihenstephan Science Centre of the TUM.

Strawberries could mitigate colonic inflammation

Inflammatory bowel disease is a set of painful conditions that can cause severe diarrhea and fatigue. Treatments can include medications and surgery. But now researchers report that a simple dietary intervention could mitigate colonic inflammation and improve gut health.

Study could shed light on potential causes and markers of inflammatory bowel disease

Unexpected patterns emerged in the microbial and viral communities of mice with intestinal inflammation during a study that examined the intestinal tracts of diseased and healthy mice.

Researchers develop biofilm formulations that protect from necrotizing enterocolitis

Most of the time, we think biofilms are bad news. And when pathogenic microbes form biofilms, they are.

Scientists discuss how common ecological models can improve gut health

When disturbances upset the balance of a forest, field, or stream, ecologists practice ecological restoration to assist ecosystem recovery.

Key metabolites shed by gut bacteria can help protect from inflammation, study finds

Researchers at Tufts University have elucidated a mechanism by which the "good" bacteria that reside in our gastrointestinal tract can help protect us from inflammation, and how their disruption (dysbiosis) can increase the susceptibility of the liver to more harmful forms of disease.

Researchers show how Spred1 molecule protects HSC homeostasis under diet-induced stress

Researchers at Kanazawa University report in Cell Stem Cell how the Spred1 molecule is involved in hematopoietic stem cell self-renewal. Experiments with mouse models show that under normal conditions, Spred1 acts as a negative regulator, while under diet-induced stress, it protects hematopoietic homeostasis.

Researchers discover how intestinal bacteria can influence blood glucose and lipid concentrations

Intestinal bacteria have attracted recent attention since they were discovered to influence various physiological functions and diseases in humans.

Acid-suppressing medicines and antibiotics in infancy linked to later allergic disease risk

The use of acid-suppressing medications or antibiotics in the first 6 months of infancy was associated with an increased risk for the subsequent development of allergic diseases in childhood.

Gut microbiome may promote pancreatic cancer by inducing immune suppression

Bacterial load was significantly higher in pancreatic tumor samples from patients with pancreatic ductal adenocarcinoma compared with pancreatic tissue from normal individuals, and in studies using mice, eliminating certain "bad" bacteria slowed the growth of pancreatic cancer, reversed immune suppression, and upregulated the immune checkpoint protein PD1.

Artificial sweetener sucralose worsens gut inflammation in mice with Crohn's disease

In a study that has implications for humans with inflammatory diseases, researchers from Case Western Reserve University School of Medicine and colleagues have found that, given over a six-week period, the artificial sweetener sucralose, known by the brand name Splenda, worsens gut inflammation in mice with Crohn's-like disease, but had no substantive effect on those without the condition.
