A family of small proteins links c-di-GMP riboswitch signaling with sporulation in Clostridioides difficile

Adriana Badilla-Lobo, Anne‐Judith Waligora‐Dupriet, Louise Penven, Roland Seifert, César Rodríguez, Frédéric Barbut, Olga A. Soutourina, Peltier Johann

This study identifies a family of small proteins regulated by c-di-GMP riboswitches that mediate sporulation in C. difficile, showing their role in spore formation and developmental regulation.

In vitro biofilms of Clostridioides difficile undomesticated strains: Morphology and properties according to strain diversity

Anaïs Lemaire, Ludovic Bridoux, Vlad Costache, Aline Crouzols, Frédéric Barbut, Sandrine Pétry, Isabelle Poquet

This study examines biofilm formation and properties of C. difficile undomesticated strains, finding that ribotype 009 strains form highly adhesive biofilms and show increased vancomycin tolerance.
