Integron diversity in bacterial communities of freshwater sediments at different contamination levels.

Abstract excerpt

Integrons, genetic elements known to be involved in the adaptation of pathogenic bacteria, were first discovered in the clinical setting. However, they are ancient structures found in various environments. When clinical integrons have a low diversity, with three integrases and gene cassettes essentially encoding antibiotic resistance, in natural environments, integrons show a greater diversity, of both gene...
