I sistemi di identificazione e caratterizzazione dei plasmidi che mediano il trasferimento orizzontale dei geni di resistenza ottenuti in questi studi sono stati adottati dai laboratori di ricerca e dai centri di sorveglianza delle malattie infettive di tutto il mondo. Siamo stati tra i pionieri ad utilizzare il sequenziamento genomico dei batteri per l&#8217;identificazione di nuovi meccanismi di resistenza e per la caratterizzazione di ceppi batterici ad alto rischio. Negli anni, le nuove biotecnologie disponibili sono state applicate per valutare l\u2019evoluzione dei batteri e per fornire strumenti di monitoraggio e di contrasto al fenomeno della resistenza agli antibiotici in ambito nosocomiale e comunitario, ma anche per migliorare le conoscenze sulla trasmissione animale-uomo dei batteri resistenti agli antibiotici.   <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-234445c elementor-widget elementor-widget-heading\" data-id=\"234445c\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"heading.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t<h4 class=\"elementor-heading-title elementor-size-default\">Conjugative plasmids selectable by short chain fructooligosaccharides as vehicles of genetic information into microbiota <\/h4>\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<div class=\"elementor-element elementor-element-5376184 elementor-widget elementor-widget-text-editor\" data-id=\"5376184\" data-element_type=\"widget\" data-e-type=\"widget\" data-widget_type=\"text-editor.default\">\n\t\t\t\t<div class=\"elementor-widget-container\">\n\t\t\t\t\t\t\t\t\t<p>Plasmids are circular molecules of DNA that can replicate autonomously in bacterial cells. The current genetic engineering technology is based on plasmids that contain an origin of replication and a resistance marker and can be introduced into bacterial recipient strain by transformation. <\/p><p>The PI of this project invented a new type of plasmid vectors (pFOS) that do not contain antibiotic resistance genes as selection markers but can be selected by a diet enriched with scFOS, short chain fructooligosaccharides. The scFOS are a group of linear fructose oligomers already available as prebiotics on the market. These sugars can escape digestion in the human upper intestine, reach the colon, and are not metabolized by most of the species belonging to the Enterobacteriaceae family. Metabolizing these sugars, a non-pathogenic <em>Escherichia coli<\/em> strain carrying the pFOS vector, is thought to have a selective advantage against other enterobacteria, transiently colonizing the gut. In addition, the pFOS vector is self-conjugative, thus has the capacity to be transferred from one bacterial strain to another bacterial recipient cell. The final pFOS technology is thought to be used <em>in vivo<\/em> to bring genetic information within a complex bacterial population (i.e., the intestinal microbiota), vehiculating genetic information to resident, autochthonous bacteria colonizing the gut of humans and animals. This project aims to construct a second-generation of pFOS plasmid variants with improved conjugation abilities and a wider bacterial host range and to measure by fermentation of cultivated microbiota the conditions of selection and stability of the constructs. Such <em>in vitro<\/em> study is fundamental to describe the microbiota response to scFOS and to select the most appropriate plasmid to become a good genetic vector for future applications of microbiome genetic engineering. The application of these vectors may help to target antimicrobial-resistant bacteria colonizing the gut of animals and humans.        <\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>Alessandra Carattoli Si \u00e8 laureata in Scienze Biologiche (1985) presso l\u2019Universit\u00e0 degli studi di Roma \u201cLa Sapienza\u201d dove ha conseguito il dottorato di ricerca in Biologia Molecolare e Cellulare (II ciclo).
