Abstract Background The continued rise of Clostridium difficile infections worldwide has been accompanied by the rapid emergence of a highly virulent clone designated PCR-ribotype 027. To understand more about the evolution of this virulent clone we made a three-way genomic and phenotypic comparison of an historic non-epidemic 027 C. difficile CD 196 a recent epidemic and hypervirulent 027 R2029I and a previously sequenced PCR-ribotype 0I2 strain 630 . Results Although the genomes are highly conserved the 027 genomes have 234 additional genes compared to 630 which may contribute to the distinct phenotypic differences we observe between these strains relating to motility antibiotic .
