Species/Subspecies: Bordetella pertussis
Etymology: Genus name: named after the Belgian microbiologist Jules Bordet (1870-1961), who first isolated B. pertussis.
Species epithet: severe cough (whooping cough).
Significance:  [Primarily in human medicine]   
Type Strain: 18-232 = ATCC 9797 = CCUG 30873 = NCTC 10739
Macromorphology (smell):
Bordetella pertussis Bordetella pertussis 
Form small pinpoint white shiny colonies (appr. diameter 1 mm), which give hemolysis on blood agar.
Micromorphology: Small non motile coccoid rods (0.2-0.5 x 0.5-1 µm), which appear singly, in pair or more rarely in chains.
Gram +/Gram -:

Metabolism: Aerobic
Other Enzymes: Urease -
Biochemical Tests: Citrate +
Fermentation of carbohydrates: Bordetella spp. does not ferment carbohydrates.
Spec. Char.: Optimal growth temperature: 35-37°C.
Hosts: Humans
Disease (Swedish):Kikhosta
Disease (English):Pertussis, whooping cough
Clinical Picture: Runny nose, sneezing, coughing (whooping cough) and fever. Adults get milder symptoms than children.
Virulence Factors: Filamentous hamagglutinin which anchors the bacteria to cilia. A tracheal cytotoxin, which inhibits the movement of the cilia, is then produced. Lipopolysaccharide (LPS), which is an endotoxin. Pertussis toxin (PT) which is an AB5-type exotoxin, helps the bacteria to colonize the respiratory tract. PT is secreted by a type IV secretion system.

 Bordetella pertussis
Eight species have been described within genus Bordetella. The four species, which are described in VetBact, are very closely related.
Comment:B. pertussis is easily spread by coughing and the incubations period is 1-2 weeks.
