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 ...

Diversity of class 1 integrons in an aquatic ecosystem
2022The emergence and rapid dissemination of antibiotic resistance is a most striking example of evolution in action, driven by lateral gene transfer. Lateral movement of genetic information is largely mediated by mobile genetic elements such as plasmids, transposons, integrons and genomic islands. These elements are able to move within or between genomes,

Imipenem-resistant Achromobacter xylosoxidans carrying blaVIM-2-containing class 1 integron
Diagnostic Microbiology and Infectious Disease, 2005We characterized seven isolates of imipenem-resistant Achromobacter xylosoxidans that were isolated from patients hospitalized in the intensive care unit at a tertiary hospital in Korea during 2001 to 2003. From the analysis with an isoelectric focusing, polymerase chain reaction, and sequencing methods, all isolates were found to produce VIM-2, OXA-30,

Detection and Characterization of Class 1 Integrons in Enterohemorrhagic Escherichia coli
Microbial Drug Resistance, 2002Enterohemorrhagic Escherichia coli (EHEC) strains isolated from humans, cattle, and food and belonging to serogroups O26 (7 strains), O111 (19 strains), and O157 (70 strains) were examined for susceptibility to 11 antimicrobial drugs. Fifty-nine strains showing resistance to at least

Class 1 integrons in environmental and clinical isolates of Pseudomonas aeruginosa
International Journal of Antimicrobial Agents, 2011The aims of this study were to ascertain the presence and spread of class 1 integrons amongst environmental and clinical isolates of Pseudomonas aeruginosa and to characterise their variable regions. A total of 76 isolates (56 clinical and 20 environmental) were studied.

Class 1 integron-associated promoters for gene cassette transcription
Russian Journal of Genetics, 2009In the present paper nucleotide sequences of inner parts of class 1 integrons (natural vectors of cloning and expression of bacterial genes) were determined for the Acinetobacter strains isolated in the Russian medical centres. The similar compositions of inserted gene cassettes are known among the strains disseminated worldwide as minimum as 10 years.

DNA as a Pollutant: the Clinical Class 1 Integron
Current Pollution Reports, 2018When humans first tried to control bacterial growth with antimicrobials, DNA elements called integrons began to accumulate genes for resistance. The clinical class 1 integron accumulated diverse antibiotic resistance genes, spread into multiple bacterial species, colonized a wide range of animal and plant hosts, and spread to every continent.

Water Research, 2012
In this study, 1832 strains of the family Enterobacteriaceae were isolated from different stages of a municipal wastewater treatment plant, of which 221 (12.1%) were intI-positive. Among them 61.5% originated from raw sewage, 12.7% from aeration tank and 25.8% from the final effluent. All of the intI-positive strains were multiresistant, i.e. resistant
