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

D Stead1, S F Park.   

Abstract

We 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 H(2)O(2), were formed during the freeze-thaw process. However, a failure to detoxify superoxide anions may lead to spontaneous disproportionation of the radicals to H(2)O(2).
