Résumé

The authors propose that the removal of oxygen protects the Salmonella from oxidative damage. The reduction in oxygen tension provides a common mode of action for protection against two entirely different inimical processes, namely, heating and freeze-thaw. They used this concept to develop a detailed hypothesis on the self-destruction of rapidly dividing cells, which they termed the suicide response. They propose that self destruction is caused by an oxidative burst which appears to result when exponentially growing cells are growth-arrested following an inimical treatment.
