Species/Subspecies: Bordetella pertussis
Categories: Causes hemolysis; primarily of interest in human medicin
Etymology: Genus name: named after the Belgian microbiologist Jules Bordet (1870-1961), who first isolated B. pertussis.
Species epithet: severe cough (whooping cough).
Significance:  [Very important]   
Taxonomy:
Phylum
Proteobacteria
Class
Betaproteobacteria
Order
Burkholderiales
Family
Alcaligenaceae 
Genus
Bordetella
Type Strain: 18-232 = ATCC 9797 = CCUG 30873 = NCTC 10739
Macromorphology (smell):
   
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 -:
 
G-
Metabolism: Aerobic
Catalase/Oxidase:+/+
Other Enzymes: Urease -
Biochemical Tests: Citrate +
Fermentation of carbohydrates: Bordetella spp. does not ferment carbohydrates.
Spec. Char.: Optimal growth temperature: 35-37°C.
Disease:
HostsDiseaseClinical picture
HumansPertussis, whooping coughRunny 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.

Taxonomy/phylogeny:
 
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.

"Dear child has many names" (call it what you will...)

For a long time, Rhodococcus hoagii was refer­red to Rhodo­coccus equi on VetBact, because we experienced some resistance to the name that is now considered to be the correct one, i.e. Rhodococcus hoagii. Now you can find the bacterium in question under the correct name in VetBact, but you can also find the bacterium when searching for the old name.
