===Infectious canine tracheitis/Kennel cough===
*''B. bronchiseptica'' acts as a primary pathogen in [[Respiratory Viral Infections - Pathology#Infectious canine tracheitis|Infectious canine tracheitis]]
*Frequently isolated from dogs with respiratory disease
*Often found with viruses or mycoplasma
*Adheres to ciliated epithelial cells in the trachea
*Colonisation and proliferation in trachea
*Releases toxins causing epithelial necrosis and prevents ciliary clearance
*Irritation to tract causes coughing
*Mortality rates low
*Peribronchial inflammation and [[Lungs Inflammatory - Pathology#Bronchopneumonia|bronchopneumonia]]
can result in unvaccinated puppies or immunosuppressed dogs
*Severe pneumonia following secondary infection e.g. with [[streptococci|Streptococci]]
*Fatal [[Lungs Inflammatory - Pathology#Bronchopneumonia|bronchopneumonia]] if occurs secondary to [[Paramyxoviridae#Canine distemper virus|canine distemper virus]]
*Transmission via respiratory secretions by direct contact or aerosol and on fomites
*Clinical signs:
**Develop within 3-4 days; persist for up to 2 weeks
**Coughing
**Gagging
**Mild serous oculonasal discharge
*Treatments includes antibiotics if coughing persists or bronchopneumonia develops
*Live intranasal vaccines
*Also found in respiratory tract of cats; can cause pneumonia in kittens; vaccine available
===Atrophic Rhinitis===
*''B. bronchiseptica'' causes [[Nasal Cavity Inflammatory - Pathology#Bacterial rhinitis|Atrophic rhinitis of pigs]] in association with [[Pasteurella species and Mannheimia haemolytica|''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
*[[Nasal Cavity Inflammatory - Pathology#Bacterial rhinitis|Atrophic rhinitis]] results when [[Pasteurella species and Mannheimia haemolytica|''Pateurella 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
