Gram-negative, straight to slightly curved rods, 0.3-0.6 x 1.2-2.0 μm. Motile by
peritrichous flagella.
peritrichous flagella.
Colonies grown on TSA at 30 ºC for 24 h are light yellow, round, smooth, convex and
translucent, 1.0-1.5 mm in diameter. Growth occurs at 10-42 ºC (optimum 30 ºC), at pH
6.0-10.0 (optimum pH 7.0) and in 0-5 % (w/v) NaCl (optimum 1 %). No fermentation in
the Hugh-Leifson test. Can grow on MacConkey agar. Facultatively anaerobic.
