Gram-negative rods, noncapsulated, 0.4 x 1.1 μm, motile by a single polar flagellum.
No accumulation of poly-beta-hydroxybutyrate.
No accumulation of poly-beta-hydroxybutyrate.
Colonies on Bordet-Gengou medium after 24 h of incubation at 37 ºC are grayish, 1
mm in diameter, and mimicked the colonies of rough phase IV strains of Bordetella
pertussis. Colonies of the two strains were less than 1 mm in diameter, entire,
smooth, semitranslucent, and glistening on brain heart infusion agar, Trypticase soy
agar, heart infusion agar and nutrient agar. No pigment production, no hemolysis on
rabbit blood agar. Produce a slight, homogeneous turbidity in brain heart infusion
broth after 24 hours at 30 ºC. Aerobic. Grow at 41 ºC, but not at 4 ºC. Grows in BHI
containing 3% NaCl, Bordet-Genou medium. No growth on LD agar, SS agar,
Pseudosel agar and NAC agar.

The source of isolation of the strains ATCC 190 and ATCC 6627 is unknown but, their former identification as strains of Bordetella
pertussis suggests that they were isolated from the human respiratory tract.
Resistant to novobiocin. Both strains produce a bacteriocin ('pertucin') that inhibits the growth of Bordetella pertussis.

Unknown. Experimental infection: dermal necrosis in guinea pigs appeared at 24 h after injection of ultrasonically disrupted cell
suspensions of ATCC 190 and ATCC 6627 only at a concentration of 10" cells/ml or higher.
