Recurrent infections and estrogen can shape the urogenital microbiota

New research indicates that recurrent urinary tract infections and estrogen can shape the urogenital microbiota in ways that may protect against recurrent infections.

New study supports link between gut bacteria and multiple sclerosis

The findings of a new research shed light on the mechanisms by which gut bacteria influence the development and progression of multiple sclerosis.

High levels of antibodies against specific gut bacteria may be linked to chronic fatigue

The findings of a new research suggest that combining Lachnospiraceae antibody screening with blood tests could improve the diagnosis of ME/CFS.

High-sugar diet could disrupt microbiota, increase odds of obesity and diabetes

The findings of a new study suggest that the interplay between diet, microbiota and intestinal immunity regulates obesity, diabetes and other metabolic conditions.

Microbial metabolite could boost efficacy of immunotherapy in pancreatic cancer

A gut microbial metabolite called trimethylamine N-oxide, or TMAO, could improve immunotherapy success in pancreatic cancer.

Altered gut microbiota linked with poorer survival after organ transplant

The findings of a new research suggest that microbiota-based therapies can help improve clinical outcomes after organ transplants.

New method tracks errant gut microbes that can trigger inflammatory diseases

Researchers have developed a new technique that can identify which gut microbes have migrated from the gut to the blood.

Gut microbes evolved with their human hosts

A recent study shows that some bacterial strains are similar to the human host phylogeny, suggesting that they evolved alongside humans.

Gut microbes may help to regulate cholesterol levels

The findings of a new study suggest that Bacteroides can metabolize cholesterol, thus helping to regulate its levels in the blood.

COVID-19 may alter lung microbiota and reduce immunity, facilitating secondary infections

COVID-19 alters the local immunity of the lung in ways that weaken the body’s antimicrobial defense and facilitate the development of secondary infections.
