| Open AccessHost immunity modulates the efficacy of microbiota transplantation for treatment of Clostridioides difficile infection
Transfer of a host’s microbiota by faecal microbiota transplantation has shown benefit in the context of recurrent Clostridioides difficle infection. Here the authors shows the inflammatory status of the recipient can impact on engraftment and the efficacy of the introduced microbiota in a model of C.difficile infection.

| Open AccessIL-33 drives group 2 innate lymphoid cell-mediated protection during Clostridium difficile infection
Here, Frisbee et al. show that hypervirulent Clostridium difficile induces IL-33 expression in the gut and IL-33 reduces mortality and morbidity via group 2 innate lymphoid cells. Furthermore, serum levels of the soluble IL-33 decoy receptor, sST2, are associated with enhanced disease severity in human C. difficile patients.

| Open AccessApoptosis of intestinal epithelial cells restricts Clostridium difficile infection in a model of pseudomembranous colitis
The enterotoxins TcdA and TcdB induce cytotoxicity of epithelial cells during Clostridium difficile infection. Here the authors show that bacterial induced epithelial cell death occurs via activation of caspases 3 and 7, resulting in apoptotic cell death.

| Open AccessA low-cost paper-based synthetic biology platform for analyzing gut microbiota and host biomarkers
Currently, gut microbiome profiling largely relies on next-generation sequencing, which is slow and expensive. Here, the authors develop a low-cost, paper-based synthetic biology platform that allows species-specific quantification of bacterial mRNAs and clinically relevant host biomarkers.

| Open AccessMultivalent display of minimal Clostridium difficile glycan epitopes mimics antigenic properties of larger glycans
Immunologically-active glycans are promising vaccine candidates but can be difficult to synthesize. Here, the authors show that pentavalent display of a minimal disaccharde epitope on a chemical scaffold can mimic a native C. difficileglycan antigen, representing a simple approach to synthetic vaccine production.
