Actualités sur les intégrons de résistance aux antibiotiques : mise au point

Integrons are bacterial genetic elements able to capture and express genes embedded within cassettes. Integrons are widely distributed notably among Gram negative bacteria. Resistant integrons are very involved in medical bacteriology due to their ability in recruiting and expressing genes encoding resistance to antibiotics. The aim of this review is to inventory recent works bringing new elements in the knowledge of resistant integrons: both on the mechanistic side with better understanding of their precise function and on the epidemiological aspect with a better appreciation of their impact in the living world.
