Integrons: natural tools for bacterial genome evolution
... Three classes of resistant integrons (RIs) have been defined on the basis of the divergence among their integrase genes, and each class appears to be able to acquire the same gene cassettes [9]. More than 70 different antibiotic resistance gene cassettes have been characterized in the three classes ...
