Genome Resequencing of the Virulent and Multidrug-Resistant Reference Strain Clostridium difficile 630

We resequenced the complete genome of the virulent and multidrug-resistant pathogen Clostridium difficile strain 630. A combination of single-molecule real-time and Illumina sequencing technology revealed the presence of an additional rRNA gene cluster, additional tRNAs, and the absence of a transposon in comparison to the published and reannotated genome sequence.
