MISMS MinION Workshop – Colombia

Training Workshop for the Implementation of MinION Sequencing for Influenza Viruses 

February 6-8, 2020

Irotama Resort

Santa Marta, Colombia

Participation is limited. Please apply by Dec 23rd.


Workshop Objective

This three-day workshop, held February 6-8th, 2020 in Santa Marta, Colombia, will introduce new technologies and advanced informatics approaches that can be used for infectious disease genomic characterization in resource-limited settings. Using the portable, low-cost Oxford Nanopore MinION sequencing platform, we will introduce the essential laboratory and computational skills required to perform extensive genetic characterization of viral pathogens, using influenza A virus as a primary demonstration. Topics will include sample preparation, bioinformatics, and phylogenetic approaches to characterize newly sequenced sampled against publicly available data.

At the completion of the workshop, attendees will be provided access and training to all essential bioinformatics tools required to establish real-time genetic characterization capabilities in their primary laboratories or at field sites using the low-cost Oxford Nanopore MinION sequencing platform. Best practices for implementing these new technologies in research, clinical, and public health laboratories will be emphasized.
