Research' Project 1 focuses on significant endemic viral pathogens from humans and viruses from animal hosts that have strong zoonotic potential. High-throughput whole-genome next-generation sequencing (NGS), combined with bioinformatics algorithms, will be used to sequence and analyze the genomes from more than 10,000 strains representing seven viral species. This will characterize the genetic diversity over a range of virus families, including many NIAID priority pathogens, to understand critical evolutionary mechanisms central to viral evolution, pathogenesis, transmission, and/or antiviral resistance. Specifically we aim to: 1) compare and contrast the genetic diversity and evolutionary dynamics of viruses circulating within and/or between humans and animal reservoirs, 2) elucidate viral-host-microbiome determinants that influence viral pathogenesis, and 3) perform deep sequencing to understand intra-host viral diversity, transmission dynamics, and antiviral resistance. Collectively, this project will use multiple genomics approaches (e.g., genomic sequencing, metagenomics, and transcriptomics) to provide the scientific community with genomic data sets of broad use from important viral families. These data will be analyzed using phylogenetics and other bioinformatics algorithms to show the spatial and temporal evolution of these pathogens. Finally, the data generated will identify, track, and predict antigenic drift/shift, recombination, escape from natural or vaccine-induced host immune responses, antiviral resistance, inter- and intra-species transmission, and the response of a host's commensal microbiota to viral infection. The information generated from these studies will help us to produce superior vaccines and antivirals, and the data sets will prove critical for rapid responses to the emergence of novel pathogens (i.e., pandemic preparedness) that arise naturally or as a result of bioterrorism.
Viruses are global pathogens that cause significant disease in humans. Frequent transmission of animal viruses to human hosts and human-to-human transmission result in outbreaks, epidemics, or pandemics. Therefore, Project 1 will target significant and emerging viral pathogens from human and animal hosts for genome sequencing in an effort to sequence virus species that could significantly impact public health.
