Gram negative rods, 0.4 to 0.6 by 1.4 to 1.8 μm, occurring singly or in pairs. Motile by
polar flagella.
polar flagella.
Colonies on nutrient agar are circular, smooth or slightly rough, entire, raised,
glistening, pale yellowish brown, opalescent, butyrous. On nutrient agar slant:
moderate growth, filiform, glistening, pale brownish yellow. Fluorescence may be
present in early stages of isolation. Optimum temperature 25 - 30 °C. No growth at 4
ºC or 37 ºC. Aerobic. Able to grow in the presence of 3-5%NaCl. Media: Nutrient Agar /
Broth, GlutamateAgar/ Broth.
