This chapter explores the use of genomics and proteomics to investigate factors responsible for the varying virulence of different Clostridium difficile strains. At first glance, the virulence of C. difficile is a simple process, in that disease is mediated by two large clostridial toxins, toxin A and toxin B. In order to maximize the power of genomic and proteomic data in the elucidation of factors responsible for C. difficile virulence, the authors performed tandem genomic and proteomic analysis on C. difficile strains exhibiting different virulence profiles. They then compared the genomic and proteomic profiles to known phenotypic data for these strains in an attempt to identify factors that could explain the differences in virulence. The chapter discusses some aspects of virulence and how proteogenome mapping has highlighted strain-to-strain differences, and gives some insight into how these differences may be linked to virulence.
