A xylose-inducible gene expression vector for Clostridium perfringens was developed. Plasmid pXCH contains a chromosomal region from Clostridium difficile (xylR-PxylB): xylR, encoding the xylose repressor, xylO, the xyl operator sequence, and PxylB, the divergent promoter upstream of xylBA encoding xylulo kinase and xylose isomerase. pXCH allows tightly regulated expression of the chloramphenicol acetyltransferase reporter and the α-toxin genes in response to the inducer concentration. Thus, pXCH could constitute a new valuable genetic tool for study of C. perfringens.
