    Clostridium difficile is a spore-forming obligate anaerobe that can remain viable for extended periods, even in the presence of antibiotics, which contributes to the persistence of this bacterium as a human pathogen during host-to-host transmission and in hospital environments. We examined the structure and function of a gene product with the locus tag CDR20291_0991 (cdPadR1) as part of our broader goal aimed at elucidating transcription regulatory mechanisms involved in virulence and antibiotic resistance of the recently emergent hypervirulent C. difficile strain R20291. cdPadR1 is genomically positioned near genes that are involved in stress response and virulence. In addition, it was previously reported that cdPadR1 and a homologue from the historical C. difficile strain 630 (CD630_1154) were differentially expressed when exposed to stressors, including antibiotics.
