POET-II trial reduces antibiotic duration for infective endocarditis by two weeks

A response-tailored strategy reduced antibiotic duration by two weeks without compromising the safety of patients with left-sided infective endocarditis.

Probiotics for mental health? A new review finds promising signals and major gaps

This narrative review examines how psychobiotics may influence anxiety, depression, bipolar disorder, and schizophrenia through gut-brain pathways involving neurotransmitters, inflammation, immune regulation, gut barrier function, and stress signaling. Specific Lactobacillus and Bifidobacterium strains showed encouraging effects, but wide differences in strains, doses, populations, and study designs currently limit clinical translation.

Scientists reviewed 20 edible and medicinal fungi for clues to better prebiotics

A review of 20 non-toxic edible and medicinal fungal species found that their polysaccharides can resist digestion, interact with gut microbes, and influence microbial metabolites linked to intestinal and metabolic health. The evidence suggests potential benefits for conditions including colitis, type 2 diabetes, and obesity, although most findings currently come from laboratory and animal studies.

Freshwater swimming linked to doubled risk of skin problems and stomach bugs

People swimming in rivers and lakes could be putting themselves at risk of nasty skin conditions and stomach bugs, according to a new study from the University of East Anglia.

Maternal immune response to urinary tract infection may drive preterm birth risk

A new study published in Science Translational Medicine shows that the increased risk of preterm pregnancies associated with urinary tract infection (UTI), is linked to the body's immune response to the infection rather than to the bacteria themselves.

Scientists identify new drug target to combat airborne tuberculosis

Tuberculosis bacteria released into the air from infected individuals dry out to form infectious particles that are second only to measles in contagiousness.

Gut bacteria may send different biological signals in Parkinson’s disease

A new study from the University of Oulu suggests that gut bacteria may send different biological signals in Parkinson’s disease.

Scientists found a distinct gut microbiome pattern in people with symptomatic diverticular disease

A multicenter Japanese study found that symptomatic uncomplicated diverticular disease (SUDD) was associated with reduced gut microbial diversity, increased abundance of the Ruminococcus gnavus group, and depletion of Coprococcus and other butyrate-producing bacteria. Predictive microbiome analysis also identified enrichment of pathways linked to exopolysaccharide biosynthesis and the cell cycle, although the observational design means these associations cannot establish causality.

Ancient proteins revived to inspire new antimicrobial treatments

University of Oregon biologists have resurrected prehistoric proteins up to 160 million years old that carry natural antimicrobial properties.

Study finds distinct patterns of innate immune activity in mental disorders

The immune system may also play a role in mental disorders. Scientists are investigating these links with brain function in greater detail, and new findings show that immune changes may differ by disorder type.

Researchers systematically map interactions between common gut bacteria

Understanding how bacteria influence one another is essential for understanding how microbial communities are formed and maintained.

Sprinters and non-athletes had similar gut diversity, but one key difference emerged

College sprint athletes showed a distinct gut microbial community structure, including higher abundance of Segatella copri and Bifidobacterium adolescentis, compared with non-athletic students. Their microbiomes also showed predicted enrichment of carbohydrate and amino acid metabolism pathways, while exploratory analyses linked several dietary factors with the signature bacteria.

New review examines why tetanus remains a global health problem

Tetanus is often considered a disease of the past, remembered mainly through childhood vaccinations and warnings about rusty nails.

Engineered immune cells help eliminate severe bacterial infections effectively

Severe bacterial infections remain a major global health challenge because antibiotics alone often fail when the host immune system becomes dysfunctional.

New genetic mutations linked to malaria drug resistance discovered

Researchers searching for genetic clues to the growing problem of malaria drug resistance identified new mutations associated with the parasite's decreased susceptibility to current treatment.

Most Americans still believe outdated antibiotic guidance, study finds

"Always finish your antibiotics" is no longer considered medical best practice for all conditions.

Study reveals hidden myxobacteria diversity for future drug discovery

Most antibiotics used clinically are based on natural compounds produced by bacteria and other microorganisms.

New study focuses on starving bacteria to prevent Lyme disease

Triggered by a near painless tick bite, Lyme disease causes severe pain and inflammation for more than 475,000 people in the U.S annually, according to the Centers for Disease Control.

New study challenges long-held view of common bacterial resident of the lungs

Our bodies are teeming with more than 35 trillion bacteria, coexisting in microbiomes inside our guts, mouths, lungs, skin and urogenital tract.

Bacterial extracellular vesicles show potential for cancer diagnosis and treatment

Bacteria shed membrane-enclosed tiny particles filled with proteins, lipids, DNA, RNA and metabolites. These particles, commonly known as bacterial extracellular vesicles (BEVs), are now being explored as possible tools for cancer diagnosis and treatment.
