Sutterella identified as a pathobiont that blocks IL-22-mediated gut protection

In a study published in Gut Microbes, researchers from the ProbiHôte team have shown that bacteria of the genus Sutterella, which are commonly found in the human gut microbiota, can exacerbate intestinal inflammation by disrupting a key pathway that protects the intestinal mucosa.     The study reveals that these bacteria inhibit activation of the […]

Understanding the intracellular dormancy of Listeria monocytogenes

Listeria monocytogenes (Lm) is a widespread pathogenic bacterium that causes listeriosis, a rare foodborne disease with one of the highest mortality rates among foodborne infections. Lm was long thought to live only in the cytosol of infected cells, but it is now known that it can also persist inside vacuolar compartments called LisCVs (Listeria-containing vacuoles). […]

Caesarean birth: sex-specific effects on the microbiota

The effects of caesarean delivery on the newborn microbiota appear to vary according to sex. A research team in Micalis demonstrates this in a mouse model, showing increased susceptibility to colonic inflammation and a compromised gut barrier in males. These findings were published in Gut Microbes. Previous studies have already shown that caesarean delivery alters […]
