Essential Genes

Dembek et al. recently published an analysis of gene essentiality in C. difficile R20291. We have generated a BioCyc SmartTable that lists all genes that were unambigously essential.

Clostridioides difficile Pathway/Genome Databases

Clostridioides difficile infections are a growing public health threat. Use of broad-spectrum antibiotics in health care settings can disrupt the normal gut microbiota and allow C. difficile to thrive. Current treatment options are limited and include additional courses of antibiotics, surgical removal of the colon, and fecal transplants.

This website contains 17 Clostridioides difficile genomes (show list) and associated metabolic pathways. This site is part of the larger BioCyc collection of thousands of Pathway/Genome Databases for sequenced genomes. Click the "Change Current Database" button (above) to explore the available databases.

This site includes extensive retrieval, visualization and analysis tools, including a genome browser and a metabolic map diagram. There are tools for analysis of gene expression, metabolomics and ChIP-chip data. You can search and align sequences for Vibrio cholerae and other microbial genomes and perform comparative analysis. You can store groups of genes and pathways into a SmartTable, and then browse, analyze and share with other users.
