Effects of segregation and selection on instability of plasmid pACYC184 in Escherichia coli B.

Abstract

We use a mathematical model to analyze the dynamics of loss of nonconjugative pACYC184 from populations of Escherichia coli B in glucose-limited continuous culture. This model incorporates both plasmid segregation and selection against plasmid carriage. It is concluded that there is intense selection against plasmid carriage (s = 0.3 per culture generation), which amplifies the frequency of segregants arising de novo.
