Single-spore germination analyses reveal that calcium released during Clostridioides difficile germination functions in a feed-forward loop.

J. W. Ribis, L. Melo, S. Shrestha, D. Giacalone, E. E. Rodriguez, A. Shen, A. Rohlfing

This study uses single-spore germination analysis to show that Ca2+ is not essential for C. difficile spore germination but can enhance germination through a feedforward loop.

Role of SpoIVA ATPase Motifs During Clostridioides difficile Sporulation

H. Benitor de la Puebla, D. Giacalone, A. Cooper, A. Shen

This study investigates how ATPase motifs in SpoIVA affect spore formation in C. difficile, showing that SipL recognizes the ATP-bound form of SpoIVA for proper coat assembly.

Ligand-Mediated Biofilm Formation via Enhanced Physical Interaction Between a Diguanylate Cyclase and Its Receptor

D. Giacalone, T. J. Smith, A. Collins, H. Sondermann, L. J. Koziol, G. O'Toole

This paper shows that the DGC GcbC enhances c-di-GMP synthesis and biofilm formation through ligand-mediated interaction with its receptor LapD, with citrate increasing this interaction.
