Mobile genetic elements in Clostridium difficile and their role in genome function

Res Microbiol. 2015 May;166(4):361-7. doi: 10.1016/j.resmic.2014.12.005. Epub 2015 Jan 7.

Abstract

Approximately 11% the Clostridium difficile genome is made up of mobile genetic elements which have a profound effect on the biology of the organism. This includes transfer of antibiotic resistance and other factors that allow the organism to survive challenging environments, modulation of toxin gene expression, transfer of the toxin genes themselves and the conversion of non-toxigenic strains to toxin producers. Mobile genetic elements have also been adapted by investigators to probe the biology of the organism and the various ways in which these have been used are reviewed.

Keywords: Bacteriophage; Conjugative transposon; Horizontal gene transfer; PaLoc; Tn5397; Tn916.
