Healthy adults who eat a diverse diet with at least 8-10 grams of soluble fiber a day have fewer antibiotic-resistant microbes in their guts, according to a study published by Agricultural Research Service scientists and their colleagues in mBio.

Microbes that have resistance to various commonly used antibiotics such as tetracycline and aminoglycoside are a significant source of risk for people worldwide, with the widely held expectation that the problem of antimicrobial resistance (AMR) — the term that refers to bacteria, viruses, and fungi th...

A study published today in the journal Cell Host & Microbe reported that the increased presence of certain bacteria in a gut biome indicates a greater likelihood that colon polyps will become cancerous.

In his research, William DePaolo, associate professor at the University of Washington School of Medicine, tracked 40 patients who had undergone routine colonoscopies and had biopsies taken near the polyps to identify bacteria present at relatively higher levels compared with those of patients who were polyp-free. All the patients were between the ages 50 and 75, and 60% were women.

“The rising incidence of colorectal cancer is a major health concern, but little is known about the composition and role of microbiota associated with precancerous polyps,” the...

Review of studies suggests a potentially useful link between gut bacteria and mental disorders. People who experience anxiety symptoms might be helped by taking steps to regulate the microorganisms in their gut using probiotic and non-probiotic food and supplements, suggests a review of studies published today in the journal General Psychiatry.

Anxiety symptoms are common in people with mental diseases and a variety of physical disorders, especially in disorders that are related to stress. Previous studies have shown that as many as a third of people will be affected by anxiety symptoms during their lifetime.

Increasingly, research has indicated that gut microbiota – the trillions of microorganisms in the gut wh...

Cleveland Clinic researchers showed that blocking a specific intestinal microbial pathway can prevent obesity and insulin resistance, as well as cause fat tissue to become more metabolically active. The team, led by J. Mark Brown, Ph.D...
