Liana Kafetzopoulou - Metagenomic nanopore sequencing: RNA viruses from lab to field
London Calling 2018
Emerging and re-emerging RNA viruses cause a significant global disease burden, ranging from mild febrile illness to haemorrhagic fevers. Rapid and unbiased identification methods, such as metagenomic MinION sequencing, are vital for the identification and characterisation of emerging pathogens for which little prior knowledge is available. Portable methodologies for field use are required during such outbreaks, especially when they occur in resource-limited settings. We have investigated a range of clinical samples using a Sequence Independent Single Primer Amplification approach and have demonstrated that metagenomic MinION sequencing can elucidate full viral genomes directly from clinical samples for Chikungunya, Dengue and Lassa virus; across clinically relevant range of viral titers. Following our results we mobilized a research team and deployed in Nigeria to test and investigate the establishment of field metagenomic sequencing using the MinION. Our pilot study was expedited and utilized to support the largest reported outbreak of Lassa fever (LASV) in Nigeria.
