Long-term storage of Campylobacter pylori

This is the authors' abstract. We don't add key points for this paper.

A reproducible method for long-term storage of Campylobacter pylori has been previously described. We cultured 10 strains of C. pylori in brucella broth that was supplemented with 10% fetal bovine serum. After incubation for 24 h, 10% glycerol and an additional 10% fetal bovine serum were added to the cultures, which when then held in storage at -70 degrees C. After 6 months, each of the strains remained viable. This technique, therefore, represents an excellent method for long-term storage of C. pylori isolates.
