Using the class 1 integron-integrase gene as a proxy for anthropogenic pollution [PDF]
Around all human activity, there are zones of pollution with pesticides, heavy metals, pharmaceuticals, personal care products and the microorganisms associated with human waste streams and agriculture.

[Integrons: gene collectors]. [PDF]
Integrons gained great interest due to their participation in resistance gene recruitment and expression. Their basic structure includes a fragment that encodes an integrase (intI) followed by a recognition sequence (attI) into which they may incorporate gene cassettes (encoding resistance mechanisms). A promoter (Pc) embedded within the integrase gene

The Natural History of Integrons [PDF]
Integrons were first identified because of their central role in assembling and disseminating antibiotic resistance genes in commensal and pathogenic bacteria. However, these clinically relevant integrons represent only a small proportion of integron diversity.

Activation of class 1 integron integrase is promoted in the intestinal environment
Class 1 integrons are widespread genetic elements playing a major role in the dissemination of antibiotic resistance. They allow bacteria to capture, express and exchange antibiotic resistance genes embedded within gene cassettes.

Resistance integrons and super-integrons [PDF]
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 gene cassettes from and into the integron, but integrons themselves are not mobile. Two groups of integrons are known: resistance integrons and super-integrons. Nearly all

Highlights • Prevalence and types of integrons vary widely across a wastewater network.• Human-impacted class 1 integrons carrying ARGs dominate, but are highest in hospital wastewater.• New qPCR assays are reported that segregate "anthropogenic" class 1

Integrons are bacterial genetic elements that can capture mobile gene cassettes. They are mostly known for their role in the spread of antibiotic resistance cassettes, contributing significantly to the global resistance crisis. These resistance cassettes

Prevalence of Antibiotic Resistome in Ready-to-Eat Salad [PDF]
Ready-to-eat salad harbors microorganisms that may carry various antibiotic resistance genes (ARGs). However, few studies have focused on the prevalence of ARGs on salad, thus underestimating the risk of ARGs transferring from salad to consumers. In this
