Nettet16. mai 2008 · Integrons facilitate the evolution of complex phenotypes by physical and transcriptional linkage of genes. They can be categorized as chromosomal integrons (CIs) or mobile resistance integrons (MRIs). The significance of MRIs for the problem of multiple antibiotic resistance is well established. Nettet20. okt. 2015 · The integron system is a natural capture system and assembly platform, which allows microorganisms to incorporate gene cassettes and further convert them to functional proteins via correct expression.
Nettet5. jun. 2015 · Class 1 integrons in E. coli from the contamination flora of meat may theoretically serve as a reservoir of resistance elements for bacteria causing human disease if the genetic structures are able to intermingle between different compartments of the E. coli population.

A cluster of multidrug-resistant P. aeruginosa … Nettet21. jul. 2024 · In this study, an integron is defined as a segment of sequence containing at least two neighboring (≤ 4 kb in distance) integron elements (integrase, attC site, or sulI) and the genes entrained among these elements. Qualified integrons are then classified into types A to E based on the integron elements they carry (Additional file 1: Figure S3).
Nettet26. feb. 2024 · A genetic element known as an integron can help to manage that burden. This piece of genetic information is formed of a succession of ‘cassettes’ containing antibiotic resistance genes. More proteins are made from the genes present at the start of the integron, compared to the ones towards the end.

These genes are embedded in a specific genetic structure called gene cassette (a term that is lately changing to integron cassette) that generally carries one promoterless open … Se mer Integrons were initially discovered on conjugative plasmids through their role in antibiotic resistance. Indeed, these mobile integrons, as they are now known, can carry a variety of cassettes containing genes that are almost … Se mer An integron is minimally composed of: • a gene encoding for a site-specific recombinase: intI, belonging to the integrase family • a proximal recombination site: attI, which is recognized by the integrase and at which gene cassettes may be inserted Se mer • Collis, CM; Kim, MJ; Partridge, SR; Stokes, HW; Hall, RM (2002). "Characterization of the Class 3 Integron and the Site-Specific Recombination System It Determines". … Se mer Cassette maintenance requires that they be integrated within a replicative element (chromosome, plasmids). The integrase encoded by the integron preferentially catalyses two types of recombination reaction: 1) attC x attC, which results in cassette excision, 2) … Se mer Integrons may be found as part of mobile genetic elements such as plasmids and transposons. Integrons can also be found in Se mer The term super-integron was first applied in 1998 (but without definition) to the integron with a long cassette array on the small chromosome of Vibrio cholerae.
