Improved preservation medium for Campylobacter jejuni

Abstract

An egg-based medium was found to be superior to the conventional Wang transport medium and the recently developed biphasic medium for the preservation of Campylobacter jejuni in the laboratory. Strains of C. jejuni preserved in egg-based medium maintained at 4° C were viable for over 3 months. The survival of C. jejuni in egg-based medium held at room temperature (27 ± 2°C) was also relatively longer than in Wang transport medium and biphasic medium.
