Roles of Fe superoxide dismutase and catalase in resistance of Campylobacter coli to freeze-thaw stress.

Author(s) : STEAD D., PARK S. F.

Type of article: Article

Summary

The authors demonstrated that oxidative stress plays a role in freeze-thaw-induced killing of Campylobacter coli following analysis of mutants deficient in key antioxidant functions. Superoxide anions, but not H2O2, were formed during the freeze-thaw process. However, a failure to detoxify superoxide anions may lead to spontaneous disproportionation of the radicals to H2O2.
