Advanced Molecular Detection (AMD)
2011: “Bioinformatics Blue Ribbon Panel”2014: Advanced Molecular Detection and Response to Infectious Disease Outbreaks (AMD) budget initiative approved by Congress
• $30M/yr public health laboratory innovation program• Focus on transformational laboratory tech & scientific computing
The AMD Program has five key objectives:1. Improve pathogen detection and characterization2. Enable new diagnostic methods to meet public health needs3. Support genomic and bioinformatics needs in the US public
health system4. Implement enhanced, sustainable, integrated information
systems5. Develop tools for prediction, modeling and early recognition
of emerging infectious threats

All 50 states have at least 1 sequencer in-house.
Began as primarily foodborne enteric bacterial pathogens• Network-driven initiative • Surveillance and outbreak detection • Transitioning from PFGE to WGS since 2014• Heavy reliance on federal partners for bioinformatics analysis
Growing dependence on WGS data• PulseNet: Complete transition to WGS for national surveillance of
major foodborne pathogens by January of 2019
Bioinformatics capacity and support continues to be one of the biggest challenges in the growth of NGS

Increasingly Universal WorkflowsWorking to establish standardized sequencing workflows for a wide range of pathogens.
Many results from a single dataset.Faster and cheaper than serial tests.
A Moving TargetRapidly evolving technology space. Changing hardware and COTS/OSS capabilities. Lots of choice, but lack of consistent standards. BIG DATA. New workforce and skillset is required.
