Description of Erysipelothrix inopinata sp. nov.

Erysipelothrix inopinata (in.o.pi.na'ta. L. fem. adj. inopinata

unexpected).

Cells are Gram-positive, catalase- and oxidase-negative,

non-motile, non-spore-forming rods, approximately 0·5 µm

in width and 1·5–3·0 µm in length. Surface colonies on

BHI (Difco) after 2 days incubation are punctiform to approximately 1· 5 mm in diameter, creamy white, undulate, convex, translucent and soft. Growth occurs under aerobic and anaerobic conditions in BHI and columbia blood media, preferably at pH 8. Growth occurs at 20 and 40 °C, but not at 45 °C. The optimal temperature for growth is 25–30 °C. Physiological properties are indicated in Table 1. DNA G+C content is 37·5 mol% ( HPLC).

Type strain is MF-EP02 T (= DSM 15511 T = CIP 107935 T). Isolated from vegetative broth used for preparation of growth media .
