strain. Non-spore-forming.
Beige colony pigmentation. Growth occurs at 30, 37 and 42 ºC. Aerobic.
Isolated from human clinical specimens (blood, sputum), industrial water. Resistant to desferrioxamine, O:129 and colistin.
Undetermined. The type strain was isolated from blood of patient at St. Thomas’ Hospital, London.
