The paper identifies resource-access breadth as a protective trait in non-toxigenic Clostridioides difficile strains, distinguishing protection from low disease potential through metabolic and competitive profiling.

The paper identifies the UNG-RPA interaction as determining whether uracil repair is high-fidelity or mutagenic in B cells.

This study shows lantibiotic-producing bacteria reduce microbiome resilience and increase susceptibility to infections after antibiotic treatment.

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 paper shows that an avirulent C. difficile strain, ST1-75, protects mice from virulent strain-induced colitis by outcompeting it through rapid amino acid depletion, suggesting potential as a biotherapeutic for CDI prevention.

This paper describes the development and characterization of a recombinant antibody that specifically detects murine gammaherpesvirus 68's vUNG protein, with applications in immunostaining, microscopy, and flow cytometry.
