Integron diversity in marine environments
Environmental Science and Pollution Research, 2015Integrons 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 ...

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 ...

Genetic Variability of Enterobacterial Resistant Integrons
Bulletin of Experimental Biology and Medicine, 2011Sulfamide-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, 2009Since 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 ...

Integrons are genetic recombination platforms that enhance bacterial evolvability by enabling the acquisition and differential expression of new genes. These genes are embedded in mobile elements, named cassettes, which can be stockpiled to form a long array of adaptive functions whose expression is driven by the Pc promoter within the integron ...

Shufflons: Multiple Inversion Systems and Integrons
Annual Review of Genetics, 1999▪ Abstract Conservative site-specific recombination functions to create biological diversity in prokaryotes. Simple site-specific recombination systems consist of two recombination sites and a recombinase gene. The plasmid R64 shufflon contains seven recombination sites, which flank and separate four DNA segments.

Class 1 integrons as invasive species
Current Opinion in Microbiology, 2017Clinical class 1 integrons are a major contributor to the evolution and dissemination of antibiotic resistance. The conserved motifs of these integrons suggest that a single, recent ancestor gave rise to all current variants. They have had a spectacular increase in distribution and abundance over the last 100 years, exhibiting many similarities to ...
