The Ares universal pathogenome assay (ARESupa) addresses important shortcomings of methods like PCR and metagenomics sequencing for microbial identification and detection of AMR markers. PCR-based tests, while accurate and fast, can only test for a small percentage of known pathogen genomes and resistance markers. While metagenomic sequencing, an emerging method for detecting a wide range of pathogen genomes, is suitable for pathogen identification, the method currently often fails to sensitively and reproducibly detect individual resistance genes or the small genome fragments indicative of AMR.
To overcome these limitations, scientists at Ares Genetics have mined ARESdb, which we believe to be an industry-leading proprietary database of genetic markers for AMR, to design a comprehensive target-enrichment next generation sequencing (NGS) panel encompassing more than 8,000 markers.
The results of a successfully completed internal study presented by Dr. Weinberger confirm the potential advantages of this approach: “When compared to metagenomic sequencing, the Ares universal pathogenome assay is proving to be more sensitive, detecting up to five times more markers for AMR. The sensitivity for AMR marker detection in native urine samples from septic patients with confirmed mono-infections in our study was determined to be between 94% and 100% when compared to comparator data obtained from whole genome sequencing of the corresponding bacterial isolate.”
Preliminary data on environmental samples confirm reproducibility down to DNA concentrations in the picogram range, demonstrating the potential suitability of this assay for the surveillance of antimicrobial resistance.
Proof of concept experiments performed in native septic urine samples suggest that data generated by using this assay are also compatible with Ares’ proprietary AI-powered bioinformatics for predictive antibiotic susceptibility testing (pAST), showing an average 92% concordance to culture and AST for E.coli and 10 tested compounds.
On May 27, 2021, Dr. Arne Materna, CEO of Ares Genetics mentioned in an invited Genomics-Track presentation at the Amazon Web Services (AWS) healthcare and life sciences virtual symposium that the Ares universal pathogenome assay (ARESupa), is currently being evaluated in a paid-for early access program for which the company has already signed up five public health organizations from different European countries.
In his presentation illustrating the benefits of machine learning for the prognostic detection of AMR, Dr. Materna confirmed that “the Ares universal pathogenome assay is part of a focused effort by Ares Genetics to commercialize solutions for pathogen and AMR surveillance from isolates and native specimen with launches having already begun and several additional ones expected during 2021.”
