Pseudomonas mosselii  
Dabboussi et al. 2002.
Gram-negative rods, motile by a single polar flagellum.
Colonies on nutrient agar are circular and nonpigmented. Nonhemolytic on blood
agar. Produce a fluorescent pigment on King B medium, but do not produce
phenazine pigments on King A medium. Temperature range for growth is 10-36 ºC;
optimal growth at 30 ºC. Growth occurs in the presence of 3 and 5% NaCl, but not in
the presence of 7% NaCl. Is able to grow on cetrimide.
Isolated from clinical specimens (blood).
Unknown. Possible opportunistic pathogen.
