Theophylline-based control of repA on a Clostridioides difficile plasmid for use in allelic exchange.

Abstract excerpt

Historically, mutagenesis in the non-model enteropathogenic bacterium Clostridioides difficile has been challenging. Developing a versatile and reliable method of generating targeted mutations in C. difficile is important to further our understanding of its pathogenesis. Some of the most common targeted mutagenesis systems rely on allelic exchange mediated by either uracil auxotrophy combined with a toxic uracil...
