In addition, focusing on variant detection, we … Our results highlighted the great potential of the amplicon-based approach to obtain consensus genomes of SARS-CoV-2 from clinical samples in just a few hours. This laboratory-based course is directed at scientists who will be generating and interpreting sequence information in their research and wish to gain a better understanding of the platforms and techniques involved, and their applications. However, we were able to obtain the genome of the studied specimens in around 8 h with the MinION, illustrating the quasi real-time sequencing capacity to effectively support health authorities. J Clin Pathol. (2020). Comparison of the genomes obtained for the clinical specimens and their respective isolates show that the sequences are strictly identical, suggesting that culture of the SARS-CoV-2 on Vero E6 cells did not induce any molecular change, at least during the first passage. Concerning the sequencers themselves, the two systems are equivalent in terms of ease of use and maintenance and are therefore both suitable for experiments in resource-limited settings. Microbiol. (2017). We found that viral genomic sequencing, even with low-throughput sequencers, could be performed with high confidence and be achieved directly from clinical specimens with significantly shortened run time. Data were manually inspected using Tablet (v1.19) (Milne et al., 2013). SARS-CoV-2, an enveloped positive-sense (+) single-stranded (ss) RNA virus, is a new member of the Coronaviridae family, Betacoronavirus genus, and the seventh coronavirus known to infect humans. Samples were considered SARS-CoV-2 positive if at least two out of three SARS-CoV-2 gene targets were detected by the RT-PCR assays. ... 2020 … Would you like email updates of new search results? The PacBio RS/RS II breaks the mold of other short reads high throughput sequencing instruments by focusing on length. To circumvent this difficulty, different techniques of enrichment can be achieved, either directly through laborious and time-consuming culture isolation or, even better, the use of specific primers targeting the whole genome of the virus (Houldcroft et al., 2017). These results underlined that high-quality sequences could be obtained with greater samples multiplexing. However, due to the high sequencing error rate around 8%, we observed that a reliable consensus sequence should be analyzed at a minimum depth coverage at 30X, or even 100X for some nucleotides. 2012 May-Jun;14(3):247-55. doi: 10.1016/j.jmoldx.2012.01.011. bioRxiv [Preprint] doi: 10.1101/2020.03.10.985150, Kafetzopoulou, L.

While ONT improved sequencing accuracy, a still relatively high error rate of the MinION raw reads (around 8%) was noticed in comparison with Illumina ones (around 0.2%), requiring a higher read depth to obtain a confident consensus sequence. Regardless of using a read depth cutoff of 10X or 30X, we obtained around 89 and 94% of SARS-CoV-2 genome coverage, for the clinical samples, respectively. It is noteworthy that the mutation D614G in the Spike glycoprotein is specific of clade A2, encompassing most of the French SARS-CoV-2 sequences. SAMtools (v1.9) was used to sort BAM files and to generate alignment statistics, coverage data, and a consensus sequence. Novel mammalian coronaviruses are regularly identified and involved in epidemics and severe diseases, such as SARS-CoV, which emerged in southern China in 2002 (Drosten et al., 2003), and MERS-CoV, first described in Saudi Arabia in 2012 and still circulating (Song et al., 2019).
