Abstract：
:Most recently published complete bacterial genomes have revealed unexpectedly high numbers of long strict repeats. In this article we discuss the various functional and evolutionary roles of these repeats, focusing in particular on their role in terms of genome stability, gene transfer, and antigenic variation.
