Distribution of class 1 integrons in a highly impacted catchment

Science of The Total Environment, 2016
Polluted compounds into freshwater sediments may select and enrich bacteria carrying specific genetic compositions. Here we examine the possible use of class 1 integrons as bioindicators in freshwater environments. Samples were collected from various sediments in an urban area (Zhangye, Gansu province, China), specifically within the city, in the ...

Multidrug resistant Aeromonas spp. isolated from zebrafish (Danio rerio): antibiogram, antimicrobial resistance genes and class 1 integron gene cassettes

Letters in Applied Microbiology, 2019
Aeromonas spp. are Gram‐negative opportunistic bacteria which have been commonly associated with fish diseases. In this study, antibiogram, antimicrobial resistance genes and integrons of 43 zebrafish‐borne Aeromonas spp. were studied.

A comparative study of class 1 integrons in Acinetobacter baumannii

Gene, 2014
Multidrug resistance (MDR) in Acinetobacter baumannii is increasingly reported and has become a significant public concern. The method responsible for the acquisition of resistance genes via integrons from the environment or intra-species in A. baumannii remains to be understood.

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.

High prevalence of imipenem-resistant and metallo-beta-lactamase-producing Pseudomonas aeruginosa in the Burns Hospital in Tunisia: detection of a novel class 1 integron

Journal of chemotherapy, 2019
Pseudomonas aeruginosa is one of the most important causes of nosocomial infections, and its eradication is very difficult due to its multidrug resistance.

Association of the blaCMY-10 gene with a novel complex class 1 integron carrying an ISCR1 element in clinical isolates from Korea

Clinical Microbiology and Infection, 2010
The blaCMY-10 gene responsible for β-lactam resistance was located on a new complex class 1 integron within a conjugative plasmid. The sul1-type class 1 integron, containing an aadA2a gene cassette, was identified upstream of blaCMY-10.

Emerging contaminants and nutrients synergistically affect the spread of class 1 integron-integrase (intI1) and sul1 genes within stable streambed bacterial communities.

Water Research, 2018
Wastewater effluents increase the nutrient load of receiving streams while introducing a myriad of anthropogenic chemical pollutants that challenge the resident aquatic (micro)biota. Disentangling the effects of both kind of stressors and their potential

Atypical Class 1 Integron Coexists with Class 1 and Class 2 Integrons in Multi-Drug Resistant Shigella flexneri Isolates from China

Current Microbiology, 2010
The antimicrobial resistance and the character of integrons were determined in 58 Shigella flexneri strains isolated from China. All isolates were multi-drug resistant and found to carry integrons of class 1 (94.8%), class 2 (100%), or both (94.8%). No intI3 was detected.

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.

Class 1 integrons as invasive species

Current Opinion in Microbiology, 2017
Clinical 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 ...
