Chryseomonas luteola  Holmes et al. 1987. Returned to Pseudomonas luteola  Anzai et al. 1997.
Chryseomonas polytricha Holmes et al. 1986 is now included in P. luteola species.
Gram negative, motile with polar multitrichous flagella, rods 0.8 by 2.5 µm rods.
R or S type, sometimes wrinkled, yellow colonies (water-insoluble pigment).
Strictly aerobic, optimal growth temperature 30 ºC. Can grow at 42 but not at 5 ºC.
Media: Nutritive agar, Trypticase Soy Agar, Mac Conkey, CASO Agar.
Isolated from clinical samples from humans and animals, also from rice paddies and rice flour.
Usually is a saprophyte of humans and animals. Can cause bacteremia, meningitis, endocarditis, peritonitis in humans & animals
(rarely).
Isolated from cat vaginal secretions (admin note).
