Malattie a trasmissione alimentare

Le malattie a trasmissione alimentare (MTA) rappresentano un serio problema di sanità pubblica. Hanno origine dal consumo di alimenti e acqua contaminati.

Molti microrganismi responsabili di MTA sono di origine zoonotica, altri di origine ambientale e possono contaminare le superfici e strumenti usati per la lavorazione degli alimenti.

L'Istituto Superiore di Sanità (ISS) svolge attività di sorveglianza delle MTA per studiarne l’epidemiologia e individuare precocemente segnali di potenziali eventi epidemici. L'ISS ospita numerosi Laboratori di riferimento che, oltre a svolgere attività analitica, supportano l’implementazione e l’armonizzazione delle attività dei laboratori locali nonché l'integrazione tra settore umano e veterinario. L'ISS svolge, infine, attività di formazione a supporto delle attività di sorveglianza epidemiologica e di laboratorio delle MTA.


null E. coli Genomics: Next Generation Sequencing (NGS) applied to the study of pathogenic E. coli

The E. coli genomics section of the previous website is meant to give the user access to information related with the E. coli genomics and Next Generation Sequencing (NGS) applied to the study of pathogenic E. coli. Efforts will be done to maintain the section constantly updated with the latest releases in the sector.
Information on the updates available will be pushed to all the EU NRL through the “Focus on” mailing list and to any other user via the RSS channel, upon subscription.
This section may also feature downloadable material, including documents related with the EURL for E. coli initiatives in the field, as well as link to usable tools to perform local analyses of NGS data.
All the software and tools included in the list are freeware and are made available directly from the authors’ websites.
Additional links are provided that direct the user to the web environments where it is possible to remotely run analyses using NGS data.
This section is also the portal to access the EURL VTEC-managed Galaxy platform ARIES. It contains tools and workflows developed by the EURL for E. coli and specifically intended for analysing E. coli genomes, as well as other bioinformatics, available on the Galaxy tool shed, for a standard QC and analysis of NGS data.
