Francisella tularensis Subtype A.II Genomic Plasticity in Comparison with Subtype A.I

Francisella tularensis Subtype A.II Genomic Plasticity in Comparison with Subtype A.I

Although Francisella tularensis is considered a monomorphic intracellular pathogen, molecular genotyping and virulence studies have demonstrated important differences within the tularensis subspecies (type A). To evaluate genetic variation within type A strains, sequencing and assembly of a new subtype A.II genome was achieved for comparison to other completed F. tularensis type A genomes. In c...

Francisella tularensis

Genomic markers for differentiation of Francisella tularensis subsp. tularensis A.I and A.II strains.

Tularemia is caused by two subspecies of Francisella tularensis, F. tularensis subsp. tularensis (type A) and F. tularensis subsp. holarctica (type B). F. tularensis subsp. tularensis is further subdivided into two genetically distinct populations (A.I and A.II) that differ with respect to geographical location, anatomical source of recovered isolates, and disease outcome. Using two human clini...

Complete Genomic Characterization of a Pathogenic A.II Strain of Francisella tularensis Subspecies tularensis

Francisella tularensis is the causative agent of tularemia, which is a highly lethal disease from nature and potentially from a biological weapon. This species contains four recognized subspecies including the North American endemic F. tularensis subsp. tularensis (type A), whose genetic diversity is correlated with its geographic distribution including a major population subdivision referred t...

Francisella tularensis: an Overview

F rancisella tularensis was first isolated in 1912 from rodents suffering from a plague-like disease in Tulare County, Calif. Subsequently, investigators learned that this small, gram-negative bacterium infects many animal species and is associated with a wide range of diseases. In humans, the bacterium causes a serious, sometimes fatal disease, called tularemia, which is also known as rabbit f...
