Gram-negative, nonsporing rods, 0.5-1.3 x 1.0-3.0 μm, motile by peritrichous flagella.
Colonies on nutrient agar are smooth, translucent, and more or less convex with
entire margins, yellow pigmented. Facultatively anaerobic, growth temperature 30-37
ºC. Grow on media: Nutrient agar or nutrient broth; Trypticase Soy Agar ± 5% sheep
blood; Luria-Bertani. No growth on KCN.

Widely distributed in nature. Isolated from water, soil, plants, human and animal feces.
Type strain was isolated from Ananas comosus.

Pantoea ananatis (Erwinia ananas / Erwinia uredovora) causes pink disease in pineapple (Ananas comosus), leafspot in syngonium
(Syngonium podophyllum), purple stain in papaya (Carica papaya), and cereal rust. One report of bacteremia in humans.
