Global Typhoid Genomics Consortium

Our Mission: We aim to engage with the global typhoid research community in order to aggregate pathogen genomic data to monitor the emergence and spread of drug resistance and inform targeted public health action. 

How We Work


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. 


Consortium membership is open to anyone, contingent on signing up to a Memorandum of Understanding and Code of Ethics. Activities are coordinated by Working Groups, with oversight from a Steering Committee and Advisory Group. Details of how to join are outlined below.


The goals of the Consortium are as follows



Resources & Publications


Code, data and resources developed / maintained by the Consortium are summarised here: https://github.com/typhoidgenomics



An overview of the Consortium's activities and the TyphiNET dashboard, along with information on additional freely available genomic analysis and visualisation resources, has been published in OFID: "Unlocking the Potential of Genomic Data to Inform Typhoid Fever Control Policy: Supportive Resources for Genomic Data Generation, Analysis, and Visualization."

The Consortium's first paper is now published in eLife: "Global diversity and antimicrobial resistance of typhoid fever pathogens: insights from 13,000 Salmonella Typhi genomes". Read the paper here.

Global Typhoid Genomics  Snapshot


Since the first Salmonella Typhi genome sequence was published in 2001, both sequencing technology and the pathogen population have changed radically. The Consortium set out to provide an updated global snapshot of typhoid genome diversity and AMR, to identify key international transmission events, and to introduce a mechanism for regular updates. 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. Thanks to a broad network of international collaborators, we were able to include 13,000 Typhi genomes from 110 countries in these analyses. All data contributors were included in the Consortium, and many have contributed to one of two analysis working groups (see below) and associated manuscripts.

Working Group 1 conducted statistical analysis and data visualisation to generate an updated overview of global genetic and AMR distribution and trends over time. This overview was developed into a manuscript, which has now been published in eLife: "Global diversity and antimicrobial resistance of typhoid fever pathogens: insights from 13,000 Salmonella Typhi genomes.

Working Group 2 has been focused on phylodynamic analyses with this Typhi dataset. Analyses and manuscript development are in advanced stages.


Other Active Consortium Working Groups


This working group's objective is to validate GenoTyphi and AMR genotyping direct from sequence reads (including nanopore reads) using the kmer-based Mykrobe typing platform (code here). This builds on an initial technical report: GenoTyphi Implementation in Mykrobe.


This working group's objectives are:
