Preferential carriage of class 2 integrons in Acinetobacter baumannii CC113 and novel singletons. [PDF]

, 2015
Our understanding of the distribution of integrons associated with multidrug resistance in Acinetobacter baumannii isolates around the world remains incomplete. The association between the class 1 and 2 integron A. baumannii-positive isolates (n = 60),

Impacts of anthropogenic activity on the ecology of class 1 integrons and integron-associated genes in the environment [PDF]

The ISME Journal, 2011
Abstract The impact of human activity on the selection for antibiotic resistance in the environment is largely unknown, although considerable amounts of antibiotics are introduced through domestic wastewater and farm animal waste. Selection for resistance may occur by exposure to antibiotic residues or by co-selection for mobile genetic ...

Class 1 integrons are low-cost structures in Escherichia coli. [PDF]

ISME J, 2017
Abstract Resistance integrons are bacterial genetic platforms that can capture and express antibiotic resistance genes embedded within gene cassettes. The capture and shuffling of gene cassettes are mediated by the integrase IntI, the expression of which is regulated by the SOS response in Escherichia coli.

Variable Gene Cassette Patterns of Class 1 Integron-Associated Drug-Resistant Escherichia Coli in Taiwan

Kaohsiung Journal of Medical Sciences, 2007
This study characterized class 1 integrons in Escherichia coli in Taiwan. The stability and changes in gene cassettes inserted into integrons were also evaluated. The study included 436 clinical strains of E. coli isolated in 2002. Class 1 integrons were

Antimicrobial resistance and class I integrons in Salmonella enterica isolates from wild boars and Bísaro pigs [PDF]

, 2011
The antibiotic resistance phenotype and genotype and the integron type were characterized in 58 Salmonellaenterica isolates recovered from Bísaro pigs and wild boars (20 S. Typhimurium, 17 S. Rissen, 14 S. Enteritidis and 7S. Havana).

Transmissible ST3-IncHI2 Plasmids Are Predominant Carriers of Diverse Complex IS26-Class 1 Integron Arrangements in Multidrug-Resistant Salmonella

Frontiers in Microbiology, 2018
Diverse mobile genetic elements (MGEs) including plasmids, insertion sequences, and integrons play an important role in the occurrence and spread of multidrug resistance (MDR) in bacteria.

Activation of class 1 integron integrase is promoted in the intestinal environment

PLOS Genetics, 2022
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. Acquisition of gene cassettes is catalysed by the class 1 integron integrase, a site-specific recombinase playing a key ...

An intrinsic control element for translational initiation in class 1 integrons [PDF]

Molecular Microbiology, 2002
SummaryIntegrons are genetic elements able to capture anti‐biotic resistance and other genes and to promote their transcription. Here, we have investigated integron‐dependent translation of an aminoglycoside 6′‐N‐acetyltransferase gene (aac(6′)‐Ib7) inserted at the attI1 site. N‐terminal sequencing revealed that translation of this gene was initiated
