  • tularensis and holarctica stored in GenBank. (cdc.gov)
  • Three subspecies (biovars) of F. tularensis are recognised (as of 2020): F. t. tularensis (or type A), found predominantly in North America, is the most virulent of the four known subspecies, and is associated with lethal pulmonary infections. (wikipedia.org)

  • holarctica (Type B) moderate North America,Europe, Asia Francisella tularensis subsp. (umd.edu)
  • Francisella tularensis Subspecies holarctica and Tularemia in Germany. (cdc.gov)
  • The only two subspecies of F. tularensis that cause severe disease in humans are the subsp. (encyclopedia.pub)
  • Francisella tularensis can cause the zoonotic disease tularemia and is partitioned into subspecies due to differences in chromosomal organization and virulence. (nebraska.edu)
  • holarctica (type B tularemia), and ssp. (cdc.gov)
  • The WGS data were compared to the prototype strain for this subspecies, specifically FSC200, which was isolated from a patient with tularemia in Europe. (nebraska.edu)
  • The subspecies holarctica (type B) is generally considered more clonal than the other subpopulations with moderate virulence compared to the hypervirulent A.I clade. (nebraska.edu)
  • F. t. holarctica (also known as biovar F. t. palearctica or type B) is found predominantly in Europe and Asia, but rarely leads to fatal disease. (wikipedia.org)
  • This subspecies lacks the citrulline ureidase activity and ability to produce acid from glucose of biovar F. t. palearctica. (wikipedia.org)
  • An attenuated live vaccine strain of subspecies F. t. holarctica has been described, though it is not yet fully licensed by the Food and Drug Administration as a vaccine. (wikipedia.org)
  • little is currently known about this subspecies or its ability to infect humans. (wikipedia.org)
  • holarctica to assess if its division into biovars I and II is associated with specific mutations previously linked to erythromycin resistance and to determine the distribution of this resistance trait across this subspecies. (nau.edu)
