Class 1 integrons in environmental and clinical isolates of Pseudomonas aeruginosa

International Journal of Antimicrobial Agents, 2011
The 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.

Multiresistant Enterobacteriaceae with class 1 and class 2 integrons in a municipal wastewater treatment plant

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

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 ...

Molecular characterization of class 1 integrons in carbapenem-resistant Enterobacterales isolates.

Microbial Pathogenesis, 2023
OBJECTIVE Carbapenem-resistant Enterobacterales (CRE) infections result in higher treatment costs and mortality rates. Integrons play important roles in emergence and spread of antibiotic resistant genes.

Strict relationship between class 1 integrons and resistance to sulfamethoxazole in Escherichia coli.

Microbial Pathogenesis, 2021
Antibiotic resistance is a health concern. Class 1 integrons (Int1) are genetic elements that contribute to the problem, as they carry different antibiotic resistance genes in their variable region, frequently dfrA (resistance to trimethoprim) and, in ...

Class 1 integron causes vulnerability to formaldehyde in Escherichia coli

Archives of Microbiology, 2021
In this study, the relationships of integron 1 element, formaldehyde dehydrogenase, and orfF genes with the level of formaldehyde resistance of isolated E. coli were investigated. E. coli bacteria were isolated from apparently healthy and colibacillosis-affected broilers of Fars Province, Iran.
