Study: Interbacterial toxins may contribute to bacterial genetic diversity

A toxin produced by bacteria as a defence mechanism causes mutations in target bacteria that could help them survive, according to a study published today in eLife.

Beneficial bacteria passed on to infants through breast milk change over time

The cocktail of beneficial bacteria passed from mother to infant through breast milk changes significantly over time and could act like a daily booster shot for infant immunity and metabolism.

Researchers investigate how CF patients respond to COVID-19

So far, based on clinical data, patients with cystic fibrosis (CF) don't appear to be especially susceptible to COVID-19, and when they do get infected, they don't seem to get sicker. But Ruobing (Ruby) Wang, MD, a physician-scientist in the Division of Pulmonary Medicine at Boston Children's Hospital, cares for patients with CF and thinks there is more to the story.

New rodent model helps identify pregnant women whose prior kidney injury also affects babies

Young pregnant women, who appear to have fully recovered from an acute injury that reduced their kidney function, have higher rates of significant problems like preeclampsia and low birthweight babies, problems which indicate their kidneys have not actually fully recovered.

New research aims to explore functions of bile acids in the gut stem cell niche

Examining gut health from a different angle, Flinders University’s Associate Professor Robyn Meech is looking at what can trigger colon cancer – and she believes bile acids may provide a significant piece of the puzzle.

Chocolate-flavored e-cigarettes are 'particularly harmful' to the lungs, study shows

New research shows chocolate-flavored e-cigarettes are "particularly harmful" to the lungs. In fact, scientists found all 10 flavors tested caused some level of toxicity in the cells lining the lungs, resulting in cell death in some instances.

Periodontitis treatment that changes oral bacteria also reduces severity of diabetes

We know that what happens in the mouth doesn't stay in the mouth - but the oral cavity's connection to the rest of the body goes way beyond chewing, swallowing and digestion.

Viral-caused cancer in California sea lions has major health implications for humans

20-plus years of data in a newly released study by The Marine Mammal Center shows ocean pollutants is one of the leading causes of cancer in sea lions and highlights how exposure to environmental contaminants can fast-track the likelihood of humans developing virally caused cancers.

Inflammation may contribute to the persistence of C. diff infection, shows study

A new study from North Carolina State University shows that the inflammation caused by Clostridioides difficile (C. diff) infection gives the pathogen a two-fold advantage: by both creating an inhospitable environment for competing bacteria and providing nutrients that enable C. diff to thrive.

Study sheds light on the causes of debilitating gut pain

A new study, published in the journal Nature, reports evidence from mice and humans that a novel mechanism contributes to chronic gut pain.

New approach to tame botulinum toxin for drug delivery

While rare, botulism can cause paralysis and is potentially fatal. It is caused by nerve-damaging toxins produced by Clostridium botulinum -- the most potent toxins known.
