Gram-positive to Gram-variable rods, 0.8-1.2 x 2.0-15.0 µm, grouped in chains.
Nonmotile. Produce ellipsoidal, subterminal endospores in unswollen to overtly
swollen sporangia. A thin capsule is produced.

Colonies are 3 mm in diameter on TSA with 5% sheep blood at 30 ºC,
non-haemolytic, creamy-gray, like sintered glass in opacity, smooth, shiny,
becoming dull with a fine crepe texture in older culture, round, entire, raised to low
convex and becoming crater form ; colony diameter on pH 5.6 agar after 3 days is
larger than 5 mm. Grow on nutrient agar and nutrient broth. Aerobic. Grow at 30 ºC
and at pH 5.6-8.
No growth in 5% NaCl broth.

Isolated in Tampa, Florida, USA, from a white powder collected on a window sill and suspected of harbouring Bacillus anthracis
during the aftermath of the anthrax bioterrorism attacks of October 2001.
Resistant to penicillin, oxacillin, ampicillin, amoxicillin and ceftriaxone.

A thin capsule is produced; genes (acpA, capA, capB, capC, capR, capD, IS1627, ORF 48, ORF 61 and repA) and capsule promoter
with more than 99.7% sequence similarity to the capsule operon of Bacillus anthracis are carried on a large plasmid.
