Global Typhoid Genomics Consortium
Our Mission: We aim to engage with the global typhoid research community in order to aggregate S. Typhi genomic data to monitor the emergence and spread of drug resistance and inform targeted public health action.
Encourage prompt sharing of typhoid genome data for public health benefit
Facilitate the extraction and reporting of key data of public health relevance
Promote and facilitate the dissemination and use of information derived from typhoid genomic data to monitor antimicrobial resistance and post-vaccination impact
Code, data and resources developed / maintained by the Consortium are summarised here: https://github.com/typhoidgenomics
The Consortium's first paper has now been preprinted and is being assessed by eLife: "Global diversity and antimicrobial resistance of typhoid fever pathogens: insights from 13,000 Salmonella Typhi genomes". Read the preprint here on MedRxiv.
Coordinate sharing & release of typhoid genomics data to maximise its potential to inform public health
The role of the consortium is to encourage and assist the deposition of raw genome data into public databases (ENA or SRA) and to coordinate downstream integration of the data for public health benefit. Members retain full control over their data and when they choose to make it public.
We use Typhi Pathogenwatch as the central analysis platform and database to generate inferred genotypes and AMR determinants from raw genomes, and to maintain a publicly available, continually updated interactive global phylogeny (described in this paper).
We are developing the TyphiNET genomic surveillance dashboard to provide interactive global and national reports on AMR, and to indicate the underlying genetic drivers based on the Pathogenwatch database.
We have established a standardised metadata template to facilitate harmonization of source information across aggregated Typhi data.
Consortium Project: 21 Years of Typhoid Genomics
In the twenty-one years since the first Salmonella Typhi genome was sequenced, both sequencing technology and the Typhi population have changed radically. Our aim is to provide an updated global snapshot of typhoid genome diversity and AMR, to introduce a mechanism for regular updates, and to facilitate use of genomic data to inform public health interventions.
All data contributors are included in the consortium, and many are contributing to analysis working groups. We aimed to involve every lab that has sequenced a Typhi genome, and to engage them in a collective effort to ensure that these data are translated for maximal public health impact.
The first paper has now been preprinted and is being assessed by eLife: "Global diversity and antimicrobial resistance of typhoid fever pathogens: insights from 13,000 Salmonella Typhi genomes". Read the preprint here on MedRxiv.
AMR prediction from typhoid genome data
We will establish a working group to collate paired genome-phenotype data in order to benchmark and refine the existing AMR predictions, and to identify gaps in knowledge to prioritise further research.
Consortium members contributing data will be expected to deposit both genome sequences and susceptibility phenotypes into NCBI's National Database of Antibiotic Resistant Organisms (NDARO) upon publication.
Coordinators: Kat Holt, Megan Carey, David Aanensen, Zoe Dyson and Stephen Baker.
