This study compares the host immune response and fitness of rough and smooth colony morphotypes of C. difficile during infection, finding that rough colonies elicit stronger immune responses but lower fitness.

This study shows Enterococcus faecalis influences phase variation in Clostridioides difficile, altering its phenotypes through the CmrRST system.

This study identifies CmrT-regulated genes mrpA and mrpB that mediate phase variation of C. difficile colony morphology by interfering with cell division.

The paper analyzes bacterial pseudo-receiver domains by comparing their amino acid composition and covariation patterns to true receiver domains, identifying functionally important regions and residue networks.

This study identifies distinct growth and chaining properties in Clade 5 Clostridioides difficile strains using time-lapse microscopy, linked to the cmr switch sequence orientation.

This study characterizes the epigenome of C. difficile and identifies a conserved DNA methyltransferase that impacts sporulation and other biological processes.
