Gram-negative rods, 0.75 x 1.75-3.6 µm. Motile by multiple polar flagella.
Non-spore-forming.
Non-spore-forming.
Colonies are smooth and circular in shape, 0.5-1.0 mm diameter after incubation in
28 ºC for 24 h on Nutrient Agar (NA) medium. Fluorescent pigment is produced in
King’s B agar medium. Produce a yellowish, mucoid biofilm on NA suplemented with
5% sucrose. Growth occurs between 4 and 37 ºC (optimally at 26-29 ºC), at pH 5-8
and with up to 4% NaCl. Strictly aerobic.

Isolated from symptomatic tomato (Solanum lycopersicum L.) in Florida.
Resistant to troleandomycin, lincomycin, rifamycin sv, lincomycin, niaproof 4, vancomycin, tetrazolium violet and tetrazolium blue.

Pathogenic to tomato causing bacterial speck disease.
Induces a hypersensitive reaction on tobacco and soft rot on potato slices.
