Bordetella bronchiseptica

B. bronchiseptica causes Atrophic rhinitis of pigs in association with Pasteurella multocida
Colonises nasopharynx
Infection must occur during first few weeks of life
Produces dermonecrotic toxin which damages osteoblasts, preventing bone formation
Leads to turbinate atrophy without distortion of the snout in uncomplicated infections
Atrophic rhinitis results when Pasteurella multocida colonises and produces osteolytic toxin, leading to bone resorption
Malformation of snout in growing pigs as well as poor growth
increases with high stocking density and poor ventilation
Vaccine available
