Completion of an important project for the identification of biodeterioration-related factors in the metallic infrastructure of the Metro, in collaboration with STASY.
Completion of an important project for the identification of biodeterioration-related factors in the metallic infrastructure of the Metro, in collaboration with STASY. The objective of the project was to detect microorganisms potentially associated with microbiologically influenced corrosion (MIC) of metallic materials, contributing to a better understanding of the factors that affect the long-term durability and maintenance of critical transport infrastructure. Metagenomic analysis was applied in this project, a modern molecular method that enables the detection of microorganisms at the species level and the characterization of microbial communities in complex environmental samples. All samples were analyzed in our laboratory in Thessaloniki, which is accredited according to ISO 17025, ensuring internationally recognized standards of quality, accuracy, and reproducibility. This initiative represents an important step toward integrating advanced molecular monitoring technologies into the management and protection of public infrastructure, strengthening the technical evidence base for targeted maintenance interventions and corrosion prevention strategies. #Metagenomics #MIC #CorrosionMonitoring #InfrastructureProtection #Metro #STASY #EnvironmentalMonitoring #ISO17025 #DNAsequence
Completion of a hospital-acquired infection prevention project at the Naval Hospital of Athens (N.N.A.)
A large-scale project for the detection of microorganisms on surfaces in the General ICU of the Naval Hospital of Athens (NNA) has been successfully completed. The aim of the project was to optimize cleaning and disinfection procedures, contributing to a safer hospital environment for both patients and staff. The project implemented metagenomic analysis, a modern molecular method for detecting microorganisms at the species level. The method also enables the parallel identification of antimicrobial resistance (AMR) genes. All samples were analyzed in our laboratory in Thessaloniki, which is accredited according to ISO 17025. This certification ensures that the results are based on internationally recognized standards of quality, accuracy, and reproducibility—critical elements for decision-making in healthcare. This represents another step toward the implementation of cutting-edge technologies in clinical practice, with a clear impact on public health and the prevention of hospital-acquired infections.
Completion of a research project at the Underground Museum of the Patriarchate of Alexandria, Egypt
The objective of the project was the analysis of multiple surface swab samples from the Underground Museum of the Patriarchate of Alexandria, aiming to understand the microbial processes that may affect historical materials and to develop targeted conservation strategies. Metagenomic analysis was applied, enabling the detection of microbial communities at species level and the identification of functional characteristics related to biodegradation, biofilm formation, pigment production, and material corrosion. All samples were analyzed in our laboratory in Thessaloniki, which is accredited according to ISO 17025. This accreditation ensures that the results are based on internationally recognized standards of quality, accuracy, and reproducibility—critical elements for decision-making in cultural heritage conservation. This activity constitutes a deliverable of the EVLOGON project, an interdisciplinary initiative that combines metagenomics, bioinformatics, artificial intelligence, and conservation for the study and protection of Christian Cultural Heritage. This project represents an important step toward integrating advanced molecular technologies and data-driven approaches into cultural heritage protection, contributing to the long-term preservation of historic sites and materials.
Significant extension of ISO 17025 accreditation for DNA Sequence SRL Hellas
DNA Sequence SRL Hellas is pleased to announce the extension of the ISO 17025:2017 accreditation of its laboratory services, further strengthening the scope and reliability of the analyses it provides in the field of metagenomics and molecular identification of microorganisms. This new extension covers additional sample types, including wastewater and upper respiratory clinical samples, substantially expanding the application of our accredited methods in areas of high importance for public health, epidemiological surveillance, and clinical practice. This development complements the company’s already accredited work in the analysis of environmental samples such as surfaces, air, soil, and water, confirming its ongoing investment in quality, scientific validation, and technological innovation. ISO 17025 accreditation ensures that all analyses are performed according to internationally recognized standards of quality, accuracy, and reproducibility, enhancing the reliability of results and their value in decision-making by healthcare organizations, research institutions, and partner organizations. With this extension, DNA Sequence SRL Hellas further strengthens its role as a pioneer in the fields of metagenomics and bioinformatics, now offering accredited solutions for an even broader range of applications — from environmental surveillance to clinical detection and the study of antimicrobial resistance. This achievement is the result of the systematic work and high level of expertise of the company’s team, as well as the trust of its partners and clients, and marks another step toward strengthening DNA Sequence SRL Hellas’ scientific and technological contribution to public health and microbial analysis.
Completion of a large-scale microorganism detection project across 43 Athens Metro stations operated by STASY
The aim of the project was to evaluate and optimize cleaning and disinfection procedures on high-touch surfaces within public Athens Metro stations, contributing to safer daily commuting conditions for both passengers and staff. Metagenomic analysis was applied in the project—a modern molecular method that enables the detection of microorganisms at the species level. All samples were analyzed in our laboratory in Thessaloniki, which is accredited according to ISO 17025. This accreditation ensures that the results are based on internationally recognized standards of quality, accuracy, and reproducibility—critical elements for decision-making in large public infrastructure systems. This initiative represents an important step toward integrating advanced molecular surveillance technologies into public transport operations, with a direct impact on public health, environmental hygiene, and the development of evidence-based cleaning strategies.
Metagenomic study for the analysis of clinical samples from Intensive Care Units (ICUs) patients.
DNASequence is pleased to announce a collaboration with the Athens Naval Hospital, in a pilot metagenomic study for the analysis of clinical samples from Intensive Care Units (ICUs) patients. This study is carried out for the first time in Greece and aims to detect pathogens and antimicrobial resistance genes with high accuracy, as well as to evaluate the laboratory and bioinformatic protocols dedicated to clinical samples. This study is also part of the effort of DNASequence to expand its services in human clinical samples.
Biosafety monitoring project inside the premises of the Athens Naval Hospital
DNASequence, with the support of Motor Oil Hellas, completed a biosafety monitoring project inside the premises of the Athens Naval Hospital, with a direction for optimization of cleaning & biosafety protocols. The project aimed to detect microorganisms on various surfaces of the hospital, as well as antibiotic resistance genes, with the ultimate goal of reducing hospital-acquired infections in the future wing of the NNA sponsored by Motor Oil.
Environmental study in the Aetoliko area
DNA Sequence is pleased to announce the completion of an environmental study in the Aetoliko area, issued for the Region of Western Greece and the Directorate of Environment and Spatial Planning. The goal is to understand the phenomenon of rapid macroalgae growth that occurs seasonally in the area, and the possible negative impact of the wastewater treatment plant. The study focuses on the detection and role of microorganisms in marine water and wastewater, that are involved in this complex phenomenon. It is the first application of metagenomics for environmental reasons, at a national level by the private sector.
