Priestia flexa ^[1] (Bacillus flexus before 2020) is an aerobic, Gram-variable, rod-shaped, endospore-forming, oxidase-positive bacterium. The endospores are ellipsoidal, located in central/paracentral, unswollen sporangia. In laboratory conditions, it produces opaque, creamish, raised-margin colonies at 30 ± 2°C when incubated for 24–72 hrs. on tryptic soy agar. This bacterial species may be isolated from feces (poultry) and soil.

Human pathogenicity has not been well described yet. ^{[2] [3]}
