Gram-positive, straight rods with rounded ends, 0.6-0.7 x 2.0-3.1 µm. Non-motile at
4, 22, 30 or 37 ºC.
4, 22, 30 or 37 ºC.
Colonies resemble typical Listeria colonies morphology. Optimum growth
temperature is 30-37 ºC. Hemolysis is not produced. CAMP-negative. Aerobic and
facultative anaerobic. Grows well on BHI agar.

Some characters were determined using API Listeria (numerical profile 2730) and
API 50 CHB/E kits.
Positive results for catalase, nitrate reduction (no nitrite reduction), acid production from: aesculin ferric citrate, N-acetylglucosamine,
amygdalin, arbutin, cellobiose, D-fructose, methyl alpha-D-glucoside, D-glucose, maltose, D-mannose, D-ribose, salicin & D-xylose.
Negative results for arylamidase, alpha-mannosidase, Voges-Proskauer test, acid production from: L- and D-arabinose, D-adonitol,
L-fucose, D-galactose, glycogen, glycerol, glucose 1-phosphate, gluconate, 2- and 5-ketogluconate, inositol, inulin, lactose, D-lyxose,
D-mannitol, melezitose, melibiose, methyl alpha-D-mannopyranoside, raffinose, L-rhamnose, L-sorbose, sucrose, D-tagatose,
turanose & methyl beta-D-xylopyranoside.
Variable results for methyl red test and acid production from D-arabitol.
