• Safety and Immunogenicity of Poultry Vaccine for Protecting Critically Endangered Avian Species against Highly Pathogenic Avian Influenza Virus, United States
  T. E. Katzner et al. View Abstract

  In 2023, an outbreak of highly pathogenic avian influenza occurred among critically endangered California condors (Gymnogyps californianus), and >21 died. We evaluated safety, immunogenicity, vaccination strategies, and correlates of antibody response of an influenza vaccine for poultry in black vultures (Coragyps atratus) and then California condors. We noted differences in antibody titers between vaccinated and unvaccinated birds (vultures p<0.004; condors p­<0.02) but no adverse effects of vaccination. All vaccinated vultures and 80% of vaccinated condors showed maximum measured antibody response within the published range associated with survival of vaccinated and virally challenged chickens. We noted weak evidence of higher antibody responses for birds given two 0.5-mL vaccines versus those given one 1-mL vaccine but no correlation between antibody titers and sex for either species or between antibody titers and bone lead concentrations in vultures. Our results prompted initiation of a vaccination program for condors that could reduce spread of this disease among highly threatened species.

• Leveraging a Strategic Public–Private Partnership to Launch an Airport-Based Pathogen Monitoring Program to Detect Emerging Health Threats
  C. R. Friedman et al. View Abstract

  Airport-based pathogen monitoring is a critical tool that can contribute to early detection and characterization of existing and new pathogen threats. A novel public–private partnership between an airport spa group, a biotech company, and the Centers for Disease Control and Prevention was instrumental in establishing a multimodal pathogen genomic surveillance program at US international airports. That public–private partnership addressed critical challenges that neither party could overcome independently, resulting in the development and deployment of a scalable, flexible early warning system for pathogen detection and public health monitoring.

• Establishing Methods to Monitor Influenza (A)H5N1 Virus in Dairy Cattle Milk, Massachusetts, USA
  E. Stachler et al. View Abstract

  Highly pathogenic avian influenza A(H5N1) virus has caused a multistate outbreak among US dairy cattle, spreading across 16 states and infecting hundreds of herds since its onset. We rapidly developed and optimized PCR-based detection assays and sequencing protocols to support H5N1 molecular surveillance. Using 214 retail milk samples from 20 states for methods development, we found that H5N1 virus concentrations by digital PCR strongly correlated with quantitative PCR cycle threshold values; digital PCR exhibited greater sensitivity. Metagenomic sequencing after hybrid selection was best for higher concentration samples, whereas amplicon sequencing performed best for lower concentrations. By establishing these methods, we were able to support the creation of a statewide surveillance program to perform monthly testing of bulk milk samples from all dairy cattle farms in Massachusetts, USA, which remain negative to date. The methods, workflow, and recommendations described provide a framework for others aiming to conduct H5N1 surveillance efforts.

• Strategies and Opportunities to Improve Community Health through Advanced Molecular Detection and Genomic Surveillance of Infectious Diseases
  J. Moore et al. View Abstract

  Advanced molecular detection (AMD) refers to the integration of next-generation sequencing, epidemiologic, and bioinformatics data to drive public health actions. As new AMD technologies emerge, it is critical to ensure those methods are used in communities that are most affected by disease-induced illness and death. We describe strategies and opportunities for using AMD approaches to improve health in those communities, which include improving access to pathogen sequencing, increasing data linkages, and using pathogen sequencing for those diseases where sequencing technologies can provide the best health outcome. Such strategies can help address and prevent differences in health outcomes in various populations, such as rural and tribal communities, persons with underlying health issues, and other populations that experience higher risks for infectious disease.

• Genomic Epidemiology for Estimating Pathogen Burden in a Population
  W. Porter et al. View Abstract

  The role of genomics in outbreak response and pathogen surveillance has expanded and ushered in the age of pathogen intelligence. Genomic surveillance enables detection and monitoring of novel pathogens; case clusters; and markers of virulence, antimicrobial resistance, and immune escape. We can leverage pathogen genomic diversity to estimate total pathogen burden in populations and environments, which was previously challenging because of unreliable data. Pathogen genomics might allow pathogen burdens to be estimated by sequencing even a small percentage of cases. Deeper genomic epidemiology analyses require multidisciplinary collaboration to ensure accurate and actionable real-time pathogen intelligence.

• Successful Transition to Whole-Genome Sequencing and Bioinformatics to Identify Invasive Streptococcus spp. Drug Resistance, Alaska, USA
  K. M. Miernyk et al. View Abstract

  The Centers for Disease Control and Prevention’s Arctic Investigations Program evaluated whole-genome sequencing (WGS) workflows and bioinformatics pipelines developed by the Centers’ Streptococcus Laboratory. We compared WGS-based antimicrobial drug resistance predictions with phenotypic testing for group B (n = 130) and group A (n = 217) Streptococcus and Streptococcus pneumoniae (n = 293). Isolates were collected in Alaska during January 2019–February 2021. We also included a historical phenotypically nonsusceptible subset. Concordances between phenotypic testing and WGS predictions were 99.9% (895/896) for group B Streptococcus, 100% (1,298/1,298) for group A Streptococcus, and 99.98% (3,516/3,517) for S. pneumoniae. Common resistance determinants were ermTR, ermB, and mef for macrolides, tetM for tetracyclines, and gyrA and parC for levofloxacin. S. pneumoniae trimethoprim/sulfamethoxazole nonsusceptibility was associated with folP gene insertions and folA mutations. In 2022, the Arctic Investigations Program transitioned Streptococcus spp. workflows to WGS, enabling more rapid monitoring and prevention of invasive disease.

• Advantages of Software Containerization in Public Health Infectious Disease Genomic Surveillance
  K. R. Florek et al. View Abstract

  Bioinformatic software containerization, the process of packaging software that encapsulates an application together with all necessary dependencies to simplify installation and use, has improved the deployment and management of next-generation sequencing workflows in both clinical and public health laboratories. Containers have increased next-generation sequencing workflow reproducibility and broadened their usage across different laboratories. We highlight the value of the State Public Health Bioinformatics community’s containerized software repository during the COVID-19 pandemic.

• Integrating Genomic Data into Public Health Surveillance for Multidrug-Resistant Organisms, Washington, USA
  L. Torres et al. View Abstract

  Mitigating antimicrobial resistance (AMR) is a public health priority to preserve antimicrobial treatment options. The Washington State Department of Health in Washington, USA, piloted a process to leverage longitudinal genomic surveillance on the basis of whole-genome sequencing (WGS) and a genomics-first cluster definition to enhance AMR surveillance. Here, we outline the approach to collaborative surveillance and describe the pilot using 6 carbapenemase-producing organism outbreaks of 3 species: Pseudomonas aeruginosa, Acinetobacter baumannii, and Klebsiella pneumoniae. We also highlight how we applied the approach to an emerging outbreak. We found that genomic and epidemiologic data define highly congruent outbreaks. By layering genomic and epidemiologic data, we refined linkage hypotheses and addressed gaps in traditional epidemiologic surveillance. With the accessibility of WGS, public health agencies must leverage new approaches to modernize surveillance for communicable diseases.
