Synonyms:
Stenotrophomonas africana, Pseudomonas hibiscicola, Pseudomonas beteli.
Gram negative, 0.5-1.5 µm, motile with polar multitrichous flagella, slightly curved rods.
S-type colonies with beta-hemolysis. Sometimes yellowish or greenish yellow (not
carotenoid). Ammonia odor can be produced by some strains on blood agar.
Strictly aerobic, optimal growth temperature 35 ºC. No growth at 4 or 41 ºC. Methionine
or cystine is required for growth.
Media: Nutritive agar, Trypticase Soy Agar, Mac Conkey agar.
Isolated from clinical specimens, milk, frozen foods, soil (rhizosphere of some cultivated plants) & water.
Respiratory and urinary infections in humans and animals. Nosocomial infections in immunocompromised organisms. Sometimes
associated with cystic fibrosis.
