Study Reveals E. coli’s Secret Weapon in Launching Infections

  • Aug. 20, 2019
Most types of Escherichia coli are harmless, but the ones that aren’t can cause severe life-threatening diarrhea. These problematic bacteria launch infections by inducing intestinal cells to form tiny structures, called pedestals, that anchor the pathogens in place and help the colonies grow.

Researchers Show How Probiotics Benefit Vaginal Health

  • Aug. 16, 2019
Researchers have shown that three genes from a probiotic Lactobacillus species, used in some commercial probiotic vaginal capsules, are almost certainly involved in mediating adhesion to the vaginal epithelium. This is likely critical to how this species benefits vaginal health. 

Study Explores Blood-Brain Barrier Leakage in CNS Infections

  • Aug. 6, 2019
A new study published in the journal mBio shines light on the breakdown of the blood-brain barrier (BBB) that occurs during many infections of the central nervous system. The findings implicate interferon gamma, a major cytokine upregulated in most central nervous system (CNS) viral infections, as a major contributor of blood brain barrier breakdown.

Mouse Genetics, More than Environment, Influences the Microbiome

  • July 26, 2019
Genetics has a greater impact on the microbiome than maternal birth environment, at least in mice, according to a study published this week in Applied and Environmental Microbiology. Vaginal birth, known to transfer microbiota to a newborn, failed to make a lasting microbial imprint on offspring.

Rise of Candida Auris May be Blamed on Global Warming

  • July 23, 2019
Global warming may have played a pivotal role in the emergence of Candida auris, according to a new study published in mBio.
