Summary: This protocol outlines the methods to perform unbiased direct metagenomic sequencing of nucleic acid extracts from cell-free fluids. This protocol can be adapted to be run on Illumina and Nanopore sequencing platforms. The protocol is based off of the work from Kafetzopoulou et al. (PMID: 30563591). Liana has provided the lab with detailed protocols, and has worked with us extensively on optimizing and getting protocols running efficiently. Please note that this protocol has been updated to use SuperScript IV with it’s optimal temperature which has been reflected in Lewandowski et al. (DOI: https://doi.org/10.1128/JCM.00963-19)Notes:* This protocol has been used to sequence influenza direction from respiratory clinical samples (DOI: https://doi.org/10.1128/JCM.00963-19).* A team from China published last week on a 2019-nCoV familial cluster using the SISPA protocol as for coronavirus whole genome sequencing (DOI: https://doi.org/10.1016/S0140-6736(20)30154-9)SISPA-Primer A - 5'-GTT TCC CAC TGG AGG ATA-(N9)-3'SISPA-Primer B - 5′-GTT TCC CAC TGG AGG ATA-3′
