Veterinary bacteriology

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]   
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 -:
Metabolism: Obligate aerobic
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.
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.

Eight species have been described within genus Bordetella. The four species, which are described in VetBact, are very closely related.


New names of bacterial phyla

The taxonomic category phylum was previously not regulated by the International Code of Nomenclature of Prokaryotes (ICNP), but now this has changed and it was decided to revise the names of bacterial phyla. All phyla must be written in italics (which has been done on VetBact also before) and have the ending -ota.

The taxonomy of chlamydias

Species within the family Chlamydiaceae were previously divided into two genera Chlamydia and Chlamydophila. However, the differences between these two genera were not that great and many research groups have not accepted this division. Therefore, the genus Chlamydophila has been returned to the genus Chlamydia and this change has now been incorporated in VetBact
