Super-integrons

Research in Microbiology, 1999
Integrons represent the primary mechanism for antibiotic resistance gene capture and dissemination among gram-negative bacteria. The recent finding of super-integron (SI) structures in the genomes of several bacterial species has expanded their role in genome evolution.

Distinct effects of struvite and biochar amendment on the class 1 integron antibiotic resistance gene cassettes in phyllosphere and rhizosphere.

Science of the Total Environment, 2018
Struvite recovered from wastewater is promising for recycling phosphorus into soil as fertilizers. However, struvite application may prompt the proliferation of antibiotic resistance in soil and plant.

Integron diversity in marine environments

Environmental Science and Pollution Research, 2015
Integrons are bacterial genetic elements known to be active vectors of antibiotic resistance among clinical bacteria. They are also found in bacterial communities from natural environments. Although integrons have become especially efficient for bacterial adaptation in the particular context of antibiotic usage, their role in natural environments in ...

Abundance of integrons in halophilic bacteria

Canadian Journal of Microbiology, 2022
Integrons are genetic platforms used for expressing open reading frames (ORFs) arranged in gene cassettes. Excision and integration of gene cassettes are controlled by their associated integron integrase (IntI). Using IntegronFinder software, we analyzed all complete halophilic genomes available in the HaloDom database, along with selected partial ...

Transcription of integron‐harboured gene cassette impacts integration efficiency in class 1 integron

Molecular Microbiology, 2011
SummaryClass 1 integrons play important roles in the dissemination of antibiotic resistance genes among bacteria. Generally, class 1 integron consists of an integrase gene (intI1), a recombination site (attI1) and a promoter (Pc) that drives the transcription of the downstreamed gene cassettes.

Integrons and Superintegrons

2014
Numerous studies have appeared that describe the importance of resistance integrons (RIs) and superintegrons (SIs) in antibiotic resistance, microbial physiology, and environmental adaptation in phylogenetically diverse gram-negative bacteria. This chapter describes the genetic organization of an integron; summarizes the different classes of RIs and ...

Integrons: agents of bacterial evolution

Nature Reviews Microbiology, 2006
Integrons are assembly platforms - DNA elements that acquire open reading frames embedded in exogenous gene cassettes and convert them to functional genes by ensuring their correct expression. They were first identified by virtue of their important role in the spread of antibiotic-resistance genes.

Genetic Variability of Enterobacterial Resistant Integrons

Bulletin of Experimental Biology and Medicine, 2011
Sulfamide-resistant (SulR) natural strains of enterobacteria (11.9% of a total of 797 cultures, isolated with enteric microflora of honeybee gut, bee-fermented pollen, and plant issues) were tested for class 1 antibiotic resistance integrons (MRI). Only 5.3% of SulR strains were MRI-positive.

Integron and antibiotic resistance

Pathology, 2009
Since the advent of antibiotic chemotherapy, the spread of drug resistance genes among clinical isolates of bacteria has become an ever-increasing problem. The increase in drug resistance has been facilitated by the association of antibiotic resistance genes with a variety of mobile genetic elements including plasmids, transposons, integrons and gene ...
