Isolation of a fibroblast mutant resistant to Clostridium difficile toxins A and B.

Microbial pathogenesis - 1 Nov 1991

Florin I

Abstract excerpt

A mutant of Chinese hamster lung fibroblasts (Don cells), resistant against Clostridium difficile toxins A and B, was isolated after mutagenization with ethylmethanesulphonate and a two-step selection with toxin B. The mutant, termed CdtR-Q, was 10(4) times more resistant to toxin B than wild-type cells and cross-resistant to toxin A (10(3) times more resistant). The resistance was overcome by increasing the dose...
