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 integron causes vulnerability to formaldehyde in Escherichia coli
Archives of Microbiology, 2021In 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.

Molecular Characterization of Class 1 Integrons in Carbapenem-Resistant Enterobacteriaceae Isolates
SSRN Electronic Journal, 2022Carbapenem-resistant Enterobacterales (CRE) infections result in higher treatment costs and mortality rates. Integrons play important roles in emergence and spread of antibiotic resistant genes. To get a better understand on the effects of integron on CRE resistance, distribution of common carbapenemase genes and class 1 integron in clinical CRE ...

Class 1 Integrons, Gene Cassettes, Mobility, and Epidemiology
European Journal of Clinical Microbiology & Infectious Diseases, 1999Integrons are genetic elements that, although unable to move themselves, contain gene cassettes that can be mobilized to other integrons or to secondary sites in the bacterial genome. The majority of approximately 60 known gene cassettes encode resistance to antibiotics. Recently, a number of gene cassettes encoding extended-spectrum beta-lactamases or

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.

Transcription of integron‐harboured gene cassette impacts integration efficiency in class 1 integron
Molecular Microbiology, 2011SummaryClass 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.

Temperature affects variations of class 1 integron during sludge anaerobic digestion
Bioresource Technology, 2022Revealing class 1 integron characteristics under different operating conditions is of great importance to control antibiotic resistance genes (ARGs) during sludge anaerobic digestion (AD). This study investigated the variations of class 1 integrons and the ARGs carried by class 1 integrons in anaerobic sludge digesters under 25 °C, 35 °C, and 55 °C ...

Distribution of class 1 integrons among enteropathogenicEscherichia coli
Canadian Journal of Microbiology, 2012The aim of this study was to investigate the incidence of and resistance gene content of class 1 integrons among enteropathogenic Escherichia coli (EPEC) and non-EPEC and to investigate intraspecies genetic diversity of EPEC strains isolated from children with diarrhea in Iran.

Distribution of class 1 integrons in a highly impacted catchment
Science of The Total Environment, 2016Polluted 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 ...

A comparative study of class 1 integrons in Acinetobacter baumannii
Gene, 2014Multidrug 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.
