Project Overview

UPGRADE addresses the urgent global challenge of antimicrobial resistance (AMR), with projections estimating over 39 million deaths by 2050. This Romanian-Moldovan collaboration establishes comprehensive genomic surveillance in university campuses—dynamic, densely populated environments where human, animal, and environmental factors converge. University campuses with over 10,000 daily interactions serve as representative urban microcosms for studying pathogen transmission and ARG circulation.

Campus surveillance

Over 100 environmental samples collected from high-traffic university locations: restaurants, cafes, study rooms, laboratories, and outdoor spaces. Comprehensive metadata including seasonal variations, temperature, humidity, and demographic data.

Nanopore sequencing

Oxford Nanopore GridION platform with R9.4.1 flow cells for 72-hour deep sequencing. Optimized DNA extraction protocols using Quick-DNA HMW MagBead Kit and automated library preparation for complex environmental metagenomics.

Romanian-Moldovan collaboration

Romania leads sample generation and sequencing infrastructure. Moldova specializes in bioinformatics framework development and data analysis. Joint dissemination through publications, conferences, and the UP-GEN platform.

UPGRADE Workflow

A comprehensive 24-month project structured into 5 work packages: from systematic campus sampling and metadata collection through Oxford Nanopore sequencing, to modular bioinformatics analysis and community platform deployment. Weekly samples collected across four seasons from university restaurants, cafes, laboratories, and public spaces.

Cognitive and Socio-Economic Impact

Scientific, cognitive and socio-economic contributions generated through environmental genomic surveillance and advanced bioinformatics.

The activities carried out generate a direct scientific impact through the development of a complete and reproducible methodological framework for environmental genomic surveillance. This includes the standardization of sampling and processing protocols, the generation of a coherent set of urban samples with associated metadata, and the implementation of an integrated bioinformatics workflow for their analysis.

The integration of these components within the UP-GEN platform enables a scalable analytical infrastructure that ensures parameter traceability, supports the integration of geospatial data, and allows robust detection of microbial taxonomy and antimicrobial resistance determinants.

These results strengthen the regional research capacity (RO–MD) to perform high-resolution metagenomic analyses aligned with international standards.

From a cognitive perspective, the work advances the understanding of urban microbiome dynamics and the mechanisms underlying the spread of antimicrobial resistance.

From a socio-economic perspective, it provides a scientific basis for evidence-based public health policies, supports urban health monitoring, and contributes to the management and mitigation of biological risks in complex environments.

Dissemination of Results
