GenomeTrakr Fast Facts





  • GenomeTrakr is the first distributed network of labs to utilize whole genome sequencing for pathogen identification.
  • Consists of 15 federal labs, 36 state health and university labs, 1 U.S. hospital lab, 2 other labs located in the U.S., 21 labs located outside of the U.S., and collaborations with independent academic researchers. More GenomeTrakr labs will be coming on-line.
  • Data curation and bioinformatic analyses and support are provided by the National Center for Biotechnology Information (NCBI) at the National Institutes of Health.
  • The GenomeTrakr network has sequenced more than 670,000 isolates and closed more than 300 genomes. The network is regularly sequencing over 12,000 isolates each month.
  • WGS can clearly define foodborne illness outbreaks.
  • WGS networks are reliable, efficient, and can provide location specificity for outbreak investigations.
  • Whole genome sequencing is inexpensive, easy to use, has identical sample prep for all pathogens, is the most accurate and high resolution subtyping technique, and a single test yields information about resistance, serotype, virulence factors, etc.
  • The need for increased number of well characterized environmental (food, water, facility, etc.) sequences may outweigh the need for extensive clinical isolates.
