Phylum Proteobacteria, Class Gammaproteobacteria, Order Pseudomonadales, Family Pseudomonadaceae, Genus Pseudomonas,
Pseudomonas pertucinogena Kawai and Yabuuchi 1975.
Synonyms: Bordetella pertusis rough variants (strains ATCC 190 and ATCC 6627).
Gram-negative rods, noncapsulated, 0.4 x 1.1 μm, motile by a single polar flagellum.
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 B . pertussis.
Colonies of the two strains were less than 1 mm in diameter, semitranslucent, entire,
smooth, and glistening on brain heart infusion agar, Trypticase soy agar, heart
infusion agar & 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. Grow in BHI containing 3% NaCl, Bordet-Genou medium. No
growth on LD agar, SS agar, Pseudosel agar & NAC agar.
The source of isolation of the strains ATCC 190 and ATCC 6627 is unknown but, their former identification as strains of B . 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.
