Targeted DNA enrichment and whole genome sequencing of Neisseria meningitidis directly from clinical specimens. cDNA was amplified using each of the two ARTIC v3 primer pools which tile the SARS-CoV-2 genome. Over the past ten years, NGS (next generation sequencing) has been widely applied to identity pathogens, characterize genetic variants, and provide a molecular basis for building additional diagnostic tools. Hundreds of millions of sequencing reads are needed to get good CLas genome coverage from an infected citrus sample, making CLas genome sequencing challenging and costly18. The ARTIC v3 libraryprepared with TruSeq library preparation achieved 99.60% coverage at a minimum of 10x and 97.31% coverage at a minimum of 100x (Fig. Samples will be run as scheduling permits, generally within 1-3 business days. The ARTIC v3 primers have been through multiple cycles of iteration to achieve relatively even amplicon balance and genome coverage [13].
