In vivo selection of resistant E. coli after ingestion of milk with added drug residues. [PDF]
, 2014 Antimicrobial resistance represents a major global threat to modern medicine. In vitro studies have shown that very low concentrations of drugs, as frequently identified in the environment, and in foods and water for human and animal consumption, can ...

Characterization of the novel In1059 harbouring VIM gene cassette
Antimicrobial Resistance and Infection Control, 2017 Background VIM-type enzyme encodes the most widely acquired metallo-β-lactamases in Gram- negative bacteria. To obtain current epidemiological data for integrons from enterobacteriae in hospital, the study characterizes the genetic structure in In1059 by

Analysis for prevalence and physical linkages amongst integrons, ISEcp1, ISCR1, Tn21 and Tn7 encountered in Escherichia coli strains from hospitalized and non-hospitalized patients in Kenya during a 19-year period (1992-2011) [PDF]
, 2013 Background: We determined the prevalence and evidence for physical linkage amongst integrons, insertion sequences, Tn21 and Tn7 transposons in a collection of 1327 E. coli obtained over a 19-year period from patients in Kenya.

Resistance integrons; A Mini review.
Caspian journal of internal medicine, 2019 Integrons are a segment of dsDNA that play a major role in bacterial adaptation and evolution. These genetic determinants are known by the presence of three necessary apparatuses: an integrase (intI gene), Pc (a promoter) and attI (a recombination site).

The evolutionary history of chromosomal super-integrons provides an ancestry for multiresistant integrons [PDF]
Proceedings of the National Academy of Sciences, 2001 Integrons are genetic elements that acquire and exchange exogenous DNA, known as gene cassettes, by a site-specific recombination mechanism. Characterized gene cassettes consist of a target recombination sequence ( attC site) usually associated with a single open reading frame coding for an antibiotic resistance

Integron Diversity in Heavy-Metal-Contaminated Mine Tailings and Inferences about Integron Evolution [PDF]
Applied and Environmental Microbiology, 2004 ABSTRACTIntegrons are horizontal gene transfer (HGT) systems containing elements necessary for site-specific recombination and expression of foreign DNA. The overall phylogenetic distribution of integrons and range of genes that can be transferred by integrons are unknown.

Antibiotic resistance in the environment, with particular reference to MRSA [PDF]
, 2008 The introduction of β-lactam antibiotics (penicillins and cephalosporins) in the 1940s and 1950s probably represents the most dramatic event in the battle against infection in human medicine.
