MedicalResearch.com: What is the background for this study? Would you describe what is meant by metagenomic sequencing?

Response: Metagenomic next-generation sequencing (mNGS) is the use of technology to generate millions of sequence reads to diagnose infection sin patients by characterizing the full range of potential pathogens (bacteria, viruses, fungi, and parasites) in a single sample. Although shown to be a promising diagnostic tool for  infectious diseases in case reports and limited case series (Chiu and Miller Nature Reviews Genetics 20, 341-355 (2019)), to date the “real-life” utility of this approach for patient care has hitherto not been demonstrated.  This study is the first prospective, multi-center study of clinical mNGS testing for the diagnosis of neurological infections in acutely ill hospitalized patients presenting with meningitis and/or encephalitis.
