Unique growth and morphology properties of Clade 5 Clostridioides difficile strains revealed by single-cell time-lapse microscopy

J. W. Ribis, C. A. Nieto-Acuna, N. DiBenedetto, A. Mehra, Q. Dong, I. L. Nagawa, I. El Meouche, B. B. Aldridge, M. J. Dunlop, R. Tamayo, A. Singh, A. Shen

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.

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.

Development of a dual fluorescent reporter system in Clostridioides difficile reveals a division of labor between virulence and transmission gene expression

M. L. Donnelly, S. D. Shrestha, J. W. Ribis, P. Kuhn, C. Feliciano, A. Shen, M. Krasilnikov

This study develops a dual fluorescent reporter system to analyze toxin and sporulation gene expression in C. difficile, revealing a division of labor between virulence and transmission gene expression under specific growth conditions.
