A New Paradigm for Threat Agnostic Biodetection: Biological Intelligence (BIOINT)

December 10, 2024

Swati Sureka, Strategy and Policy Analyst, Arctic Slope Regional Corporation (ASRC) Federal

Swati Sureka selfie

Just as remote imaging formed the basis for a new domain of geospatial intelligence (GEOINT) spanning military and civilian applications, we posit that agnostic sequencing of environmental nucleic acid samples should drive a paradigm shift in how we seek to understand our biological world. This new paradigm, which we call “biological intelligence,” builds on novel technologies and trends in biosurveillance, and differs from traditional approaches in critical ways. 

 

 

 

Preparing for the Next Outbreak: Designing Closer Collaboration between Healthcare and Public Health to Deploy Pathogen-Agnostic Testing as an Early Warning System

November 13, 2024

Dr. Adi V. Gundlapalli, Senior Advisor, Centers for Disease Control and Prevention 

Adi Gundlapalli

The surveillance and identification of emerging, reemerging, and unknown infectious disease pathogens is essential to national public health preparedness and relies on fluidity, coordination, and interconnectivity between public and private pathogen surveillance systems and networks. Developing a national sentinel surveillance network with existing resources and infrastructure could increase efficiency, accelerate the identification of emerging public health threats, and support coordinated intervention strategies that reduce morbidity and mortality. This presentation will provide an overview of our recent efforts to understand the roles of clinicians, healthcare entities, clinical laboratories, and federal agencies in pathogen-agnostic metagenomic sequencing in the US.

 

Challenges and Opportunities in Pathogen Agnostic Sequencing for Public Health Surveillance 

October 29, 2024

Drs. Matthew Kasper and Lindsay Morton, Department of Defense Global Emerging Infections Surveillance (GEIS) Program

Matthew Kasper and Lindsay Morton

In this talk, we will highlight opportunities and challenges for the implementation of pathogen agnostic sequencing in the context of the wider global community.

Pathogen agnostic sequencing is crucial for biodefense and public health, aiding in infectious disease detection and monitoring. The US government’s commitment is evident in the latest National Biodefense Strategy, American Pandemic Preparedness Plan, and 2023 Broad Agency Announcements from the Department of Health and Human Services, including the CDC and BARDA.

Next-generation sequencing (NGS) technologies, which offer higher-throughput genome sequencing, have become more affordable and widely adopted in biomedical and public health labs. The reduced cost per genome or sample has made NGS a key part of routine public health surveillance. 

Exploring List-Based Approaches and Potential Threat Agnostic Applications in U.S. Biodefense and Public Health – Toward a Hybrid Approach

July 16, 2024

Dr. Yong-Bee Lim, Deputy Director of Converging Risks Lab, and Dr. Saskia Popescu, Professor at the University of Maryland

Following the COVID-19 pandemic and with the U.S. struggling to respond to a complex H5N1 outbreak, traditional approaches to preventing and responding to biological threats have underscored a need for a more agile and robust strategy. Evolving technical capabilities and lessons learned from recent outbreaks have provided us with an array of opportunities to strengthen bioresilience, but ultimately this requires a spectrum of tactics. In this presentation, Drs. Lim and Popescu discuss the current list-based approach to biodefense and public health within the U.S., but also explore an increasing need for threat-agnostic pathways for addressing the growing risk of outbreaks.

Computational and Systems Biology Advances to Enable Bioagent Agnostic Signatures

June 18, 2024

Andy Lin, Computational Biologist, Pacific Northwest National Laboratory

Andy Lin in Seattle

Enumerated threat agent lists have long driven biodefense priorities. The global SARS-CoV-2 pandemic demonstrated the limitations of searching for known threat agents as compared to a more agnostic approach. Recent technological advances are enabling agent-agnostic biodefense, especially through the integration of multi-modal observations of host-pathogen interactions directed by a human immunological model. Although well-developed technical assays exist for many aspects of human-pathogen interaction, the analytic methods and pipelines to combine and holistically interpret the results of such assays are immature and require further investments to exploit new technologies. In this talk, we discuss potential immunologically based bioagent-agnostic approaches and the computational tool gaps the community should prioritize filling.

Assessing the Zoonotic Risk of Pre-emergent Viruses

February 20, 2024

Tony Goldberg, PhD, Professor, School of Veterinary Medicine, University of Wisconsin-Madison

Tony Goldberg

Exploration of the “virosphere” is in its golden age. The sheer number of new viruses discovered daily, and the fact that most cannot be cultured, creates enormous about where to allocate attention and resources. It is not an intractable problem, however, to distinguish those few viruses that are likely to emerge as zoonoses from the many others that are not. This talk describes two diametric approaches to addressing this problem. The first approach involves a field-to-lab investigative methodology that, when combine with biologically informed predictive computational models, can assess the zoonotic risk of viruses that have not yet been identified in humans. The second approach relies on the power of modern methods in anthropology and ethnography to identify zoonotic transmission pathways, even before the identification of any pathogens that might traverse those pathways. A unifying example is simian hemorrhagic fever virus and its relatives in the family Arteriviridae, which cause important animal diseases but have never been documented to infect humans.  Both approaches identify these viruses as high-risk pre-emergent zoonoses.

RNA? No way! Or, is it OK? Planetary Protection and the Interaction Potential for Fragments Returned to the Earth’s Biosphere from Asteroid or Cometary Material

January 16, 2024

Betsy Pugel, PhD, Planetary Protection Group Lead, NASA Goddard Space Flight Center

Betsy Pugel

Spacefaring nations that investigate and return samples from planetary bodies comply with requirements that seek to preserve the microbial and organic integrity of that body when exploring there and that of our own Earth’s biosphere when returning samples.  This is a part of the discipline known as Planetary Protection.   When NASA returns samples from planetary bodies, those extraterrestrial samples can be subject to containment if the environment may support life as we currently know it.  At present, Mars,  a moon of Jupiter (Europa) and a moon of Saturn (Enceladus) are the planetary bodies that are subject to containment of samples when they return to Earth.  The temperature, presence of water and levels of ionizing and non-ionizing radiation present may support that life and so, interaction potential between those extraterrestrial samples and Earth are reduced by taking containment or sterilization measures, known as Restricted Earth Return. Currently, much of our solar system, including our moon, Mercury, Venus, Jupiter, Saturn, Uranus, Neptune, and Pluto as well as asteroids and comets, are Unrestricted Earth Return missions, as the scientific consensus is that the lack of water, temperature extremes and radiation extremes make it unlikely for life as we know it to survive.  

Is there evidence to start to ponder the re-evaluation of that threat from Unrestricted Earth Returns?  Recent discoveries of uracil from asteroidal material raises the question of interaction potential between previously perceived non-threat materials from asteroids and comets with our biosphere. As there are common mechanisms for the generation of life on Earth in the Early Earth phases that are common to chemical interactions observed in samples returned from asteroids and comets, does that common chemistry hold any additional interaction threat when returned to Earth? At what level—base pairs? RNA? DNA? Microbial?  How can risk be determined (interaction potential) for extraterrestrial RNA or DNA arriving to our local biosphere?  What kinds of mitigations, if any, such as sample containment, need evaluation for future asteroidal or cometary missions? 

Advances in Functional-Based Assays for Detection of Novel Pathogens 

July 25, 2023

Zach Stromberg, PhD, Biomedical Scientist, Pacific Northwest National Laboratory 

Zachary Stromberg - Biomedical Scientist - Pacific Northwest National Laboratory

Functional assays exploit host-pathogen interactions as the basis of pathogen detection and often rely on detecting host responses during infection. Common pathogenic traits assessed may be produced by the pathogen itself (e.g., toxin production) and by the interaction of the pathogen with the host (e.g., cell death). Unlike conventional detection methods that target specific microbial sequences, functional assays are based on pathogen strategies used during the infection process. Platforms for high-throughput functional characterization have been elusive due to the challenge of creating an integrated system for pathogen extraction, interrogation, and assessment. Here, the development of an end-to-end pipeline for discovery of pathogenic features and detection of pathogens in real-world environmental samples will be discussed.

Intelligent Immunity - Drawing from Innate Immune Mechanisms to Design Pathogen-agnostic Diagnostics for Emerging Threats 

June 15, 2023

Harshini Mukundan, PhD, Program Manager, Office of National Homeland Security (ONHS)

Harshini Mukundan

Harshini Mukundan is a program manager for chemical and biological technologies at ONHS, and also a scientist in the biosciences area. Harshini will cover the human innate immune system as a classical example of a pathogen agnostic diagnostic and therapeutic system. Mimicking innate immunity in the laboratory can allow for the universal identification of emerging threats, increasing our preparedness against future pandemics and biowarfare events. We have been working on understanding core principles guiding host-pathogen interactions and adapting them to design tailored assays for the direct detection of pathogen signatures in complex clinical samples. A snapshot of design to deployment of this approach - including preliminary clinical studies in blinded cohorts will be presented. Finally, we will touch on current work intended to expand the scale of this understanding to achieve a machine learning model of innate immunity that is truly agnostic.

Evolution on Thoughts for Host-based Therapeutic Approaches to Current and Future Threats

February 16, 2023

George Korch, PhD, President, GeoBIO LLC

George Korch, PhD, President, GeoBIO LLC

The recent, ongoing pandemic of SARS CoV-2 coronavirus is just an added example of how novel pathogens continue to emerge and how we have typically responded with heroic efforts to quickly develop and produce new vaccines, diagnostics and treatments.  All medical countermeasures take time to become ready for population use and distribution, even in the most urgent and highly resourced efforts. What if we more seriously considered looking at host-based therapeutics to augment our pathogen-focused efforts, and what if there are major patterns in the interaction of hosts and pathogens across diverse taxa that could yield multiple new therapeutics?
