Species/Subspecies: Bordetella bronchiseptica
Categories: Zoonotic; causes hemolysis; motile
Etymology: Genus name: named after the Belgian microbiologist Jules Bordet (1870-1961), who first isolated B. pertussis.
Species epithet: with an infected bronchus.
Significance:  [Very important]   
Taxonomy:
Phylum
Proteobacteria
Class
Betaproteobacteria
Order
Burkholderiales
Family

Genus
Bordetella
Type Strain: ATCC 19395 = CCUG 219 = NCTC 452
Macromorphology (smell):
     
Small greyish white and shiny colonies (1-2 mm in diameter after 24-48 hours incubation). May give a thin zone of hemolysis on bovine blood agar (but not on horse blood agar).
Micromorphology: Small motile rods (0.2-0.5 x 0.5-2.0 µm), which appear singly or in pairs.
Gram +/Gram -:
 
G-
Metabolism: Obligate aerobic
Catalase/Oxidase:+/+
Other Enzymes: Tryptophanase (indol) -, urease +
Biochemical Tests: Citrate +
Fermentation of carbohydrates: Bordetella spp. does not ferment carbohydrates.
Spec. Char.: Optimal growth temperature: 35-37 °C.
Special Media:
Bordetella bronchiseptica  
Smith-Baskerville medium is a selective medium, which is used for cultivation of B. bronchiseptica.
Disease:
HostsDiseaseClinical picture
PigsAtrophic rhinitisSneezing, nasal turbinates and bone deformity of the snout especially with infection together Pasteurella multocida
DogsCanine infectious tracheobronchitis (kennel cough)Coughing, gagging or retching, serous oculonasal discharge. Spreads rapidly.
Often secondary to viral infection
CatsTracheobronchitis, conjunctivitis and pneumoniaSneezing, nasal discharge, but coughing is not a characteristic feature
Rabbits and small rodents (laboratory animals)PneumoniaOculonasal discharge, dyspne and anorexia.
Subclinical infections are common.
Virulence Factors: Fimbriae (adhesins), LPS, cytotoxins, typ III secretion system.
