Weyant et al. 1995.

Old synonym: CDC nonoxidizer group 2 (NO-2).
Gram-negative small, coccoid and short rods (longer rods occasionally observed).
Nonmotile.
Colonies on Bordet-Gengou medium are smooth, convex, pearly, glistening, nearly
transparent. Growth characteristics on blood agar are similar to those of
B.
parapertussis
. Narrow zone of haemolysis. Fastidious. Optimum growth
temperature is 37 ºC. No growth at 25 and 42 ºC. Strictly aerobic. Growth occurs on
MacConkey agar in 3 to 7 days of incubation at 35 ºC. No growth on Simmons citrate
agar, Salmonella-Shigella agar, cetrimide agar, nutrient broth with 6% NaCl (but
grows in nutrient broth with 0% NaCl in 2-7 days). Produce a brown soluble
pigment. Diffuse zones of browning may be observed around colonies, especially in
media supplemented with tyrosine.
Isolated from blood and upper respiratory tract cultures of humans.
Associated with septicemia, endocarditis, and respiratory failure in humans.
