Study of probiotic yeast behaviour in the gut

Researchers examined how the probiotic yeast Saccharomyces boulardii acts in the gut to guide future drug delivery. They measured yeast gene activity in germ‑free mice and found gut‑active promoters and signs of safety.

Environment shapes gut bacteria of Etosha herbivores

Researchers sampled feces from 11 herbivore species in Etosha National Park, Namibia, and used DNA sequencing to test for phylosymbiosis. Five closely related bovid species showed the pattern, while others did not.

Sourdough study shows how microbes live together

Researchers at Tufts University used real sourdough starters to test whether simple pairwise interactions can predict which microbes coexist. The model worked well and improved when it included the starter’s feeding-and-use cycle.

New drug pair helps fight rifampicin-resistant tuberculosis

Scientists paired rifampicin with a probe called AAP-SO2 that binds bacterial RNA polymerase at a different site and slows transcription. The pair killed resistant mutants in culture and was especially effective in a rabbit model.

Yale reveals molecular structure of cholera flagella

Yale researchers imaged the molecular structure of Vibrio cholerae flagella in living bacteria. The study shows how flagella proteins sit inside a hydrophilic sheath and suggests the sheath helps the bacterium move and infect cells.

Microbes help tell how old termite pellets are

A University of California, Riverside study found that microbes in termite pellets change after exposure to air. Measuring bacterial DNA over time can distinguish fresh from old pellets and could enable a quick on-site test.

Microbes colonize new lava at an Iceland volcano

Scientists sampled fresh lava at the Fagradalsfjall volcano after eruptions between 2021 and 2023. They tracked how microbes arrived, how diversity changed after the first winter, and where the microbes likely came from.

New method builds synthetic phage genomes

Researchers developed a way to build complete bacteriophage genomes and edit single genes. The method addresses problems with hard-to-synthesize DNA and could speed matching phages for bacterial infection treatment.

Sorbitol can become fructose and affect the liver

Researchers found that sorbitol can turn into fructose in the liver and may harm the organ. The study used zebrafish and was led by Gary Patti; the results raise questions about some sugar substitutes.

Scientists find many new gut microbes in Africa

A large study of stool samples from around 1,800 women across four African countries found thousands of previously unknown gut microbes. The results may change how medicines and HIV care work for African populations.
