Evaluation of the Galileo™ Pathogen Solution Next-Generation Sequencing Pipeline for the Identification and Quantification of DNA Viruses in Transplant Patients
Solid organ and hematopoietic stem cell transplant recipients are uniquely susceptible to infections, often with increased severity, due to a number of common and opportunistic viruses. Next-generation sequencing (NGS) has the potential to enable clinicians to determine the presence and abundance of transplant-related viruses with unprecedented precision, as well as identify co-infections in an unbiased manner.

Evaluation of a Next-Generation Sequencing Metagenomics Assay to Detect and Quantify DNA Viruses in Plasma from Transplant Patients
Viral infections are major causes of morbidity and mortality in solid organ and hematopoietic stem cell transplant patients. The Galileo Pathogen Solution RUO assay is a sample to result metagenomic pipeline designed to simultaneously detect and quantify 10 DNA viruses.

Performance of an NGS-based Metagenomics Assay to Simultaneously Detect and Quantify Multiple DNA Viruses
Galileo Pathogen Solution is a sample to report mNGS pipeline for comprehensive pathogen detection that eliminates the need to
query specific pathogens independently. In this RUO beta study, we demonstrate the use of an mNGS pipeline using Arc Bio Galileo
Pathogen Solution (GPS) for identification of DNA viruses in residual EDTA plasma specimens by comparing with standard of care qPCR assays.

Megaplasmids on the Rise: Combining Sequencing Approaches to Fully Resolve a Carbapenemase – Encoding Plasmid in a Novel Pseudomonas Species
Horizontal transfer of plasmids plays a pivotal role in the dissemination of antibiotic resistance genes and emergence of multidrug-resistant bacteria. Here, we combined Nanopore and Illumina sequencing to fully assemble a carbapenemase-encoding megaplasmid carried by an isolate belonging to a putative novel Pseudomonas species.

Metagenomic Next-Generation Sequencing for Identification and Quantitation of Transplant-Related DNA Viruses
Infections with DNA viruses are frequent causes of morbidity and mortality in transplant recipients. This study describes the analytical and clinical performance characteristics of the Arc Bio Galileo Pathogen Solution, an all-inclusive metagenomic next-generation sequencing (mNGS) reagent and bioinformatics pipeline that allows the simultaneous quantitation of 10 transplant-related double-stranded DNA (dsDNA) viruses (adenovirus [ADV], BK virus [BKV], cytomegalovirus [CMV], Epstein-Barr virus [EBV], human herpesvirus 6A [HHV-6A], HHV-6B, herpes simplex virus 1 [HSV-1], HSV-2, JC virus [JCV], and varicella-zoster virus [VZV]). The mNGS 95% limit of detection ranged from 14 copies/ml (HHV-6) to 191 copies/ml (BKV), and the lower limit of quantitation ranged from 442 international units (IU)/ml (EBV) to 661 copies/ml (VZV). An evaluation of 50 residual plasma samples with at least one DNA virus detected in prior clinical testing showed a total percent agreement of mNGS and quantitative PCR (qPCR) of 89.2% (306/343), with a κ statistic of 0.725. The positive percent agreement was 84.9% (73/86), and the negative percent agreement was 90.7% (233/257). Furthermore, mNGS detected seven subsequently confirmed coinfections that were not initially requested by qPCR. Passing-Bablok regression revealed a regression line of y = 0.953x + 0.075 (95% confidence interval [CI] of the slope, 0.883 to 1.011; intercept, –0.100 to 0.299), and Bland-Altman analysis (mNGS – qPCR) showed a slight positive bias (0.28 log10 concentration; 95% limits of agreement, –0.62 to 1.18). In conclusion, the mNGS-based Galileo pipeline demonstrates analytical and clinical performance comparable to that of qPCR for transplant-related DNA viruses.
