Gram-negative small rods with rounded ends, 0.2 x 1.2 μm, occuring single or in
pairs. Motile.
Colonies are slightly convex, translucent and non-pigmented, with smooth margins,
and 0.5-1 mm in diameter after 72 h of incubationon trypticase soy agar at 28 ºC. Not  
haemolytic on horse blood agar. No growth on cetrimide agar or on acetamide.
Can grow at 30, 37 and 42 ºC. No growth in nutrient broth with 3% NaCl. No
fluorescence on King’s B medium. Aerobic and anerobic growth.
Isolated from isolated from sputum of a cystic fibrosis patient in USA.
Undetermined.
