Phase variation

Phase variation is a method for dealing with rapidly varying environments without requiring random mutation employed by various types of bacteria, including Salmonella species. It involves the variation of protein expression, frequently in an on-off fashion, within different parts of a bacterial population. Although it has been most commonly studied in the context of immune evasion, it is observed in many other areas as well.
