The integron is a powerful system which, by capturing, stockpiling, and rearranging new
functions carried by gene encoding cassettes, confers upon bacteria a rapid adaptation …

Class 1 integrons have played a major role in the global dissemination of antibiotic
resistance. Reconstructing the history of class 1 integrons might help us control further …

Integrons are genetic elements composed of a gene encoding an integrase, gene cassettes
and an integration site for the gene cassettes (att). The integrase excises and integrates the …

Integrons are bacterial genetic elements that can capture, rearrange, and express mobile
gene cassettes. They are best known for their role in disseminating antibiotic-resistance …

Background Class 1 integrons contain genetic elements for site-specific recombination,
capture and mobilization of resistance genes. Studies investigating the prevalence …

DNA sequencing, phylogenetic and mapping studies suggest that the class 1 integron found
in pathogens arose when one member of the diverse family of environmental class 1 …

The integron is a new type of mobile element which has evolved by a site-specific
recombinational mechanism. Integrons consist of two conserved segments of DNA …

Although recently discovered, integrons have played a primordial role in the evolution of
bacterial genomes. They are best known as the genetic agents responsible for the capture …

Objectives Integrons are bacterial genetic elements that can capture and express genes
contained in mobile cassettes. Integrons have been described worldwide in Gram-negative …

Integrons are genetic elements known for their role in the acquisition and expression of
genes conferring antibiotic resistance. Such acquisition is mediated by an integron-encoded …
