yes
what cellular changes occur in chronic bronchitis
increased goblet cell nos, hyperplasia of submucosal glands+ increased mucus
ciliated epithelium> squamous metaplasia
secondary bacterial infection common
which sp/br prone to chronic bronchitis
small toy dog breeds
how would chronic bronchitis appear on
radiograph
BAL
xray: thickened bronchial walls: donuts and tramlines
BAL: +++ mucus, + neutrophils and macrophages, + squamous metaplasia of CCECs (ciliated columnar epithelial cells)
–bacteria, usualy -ve with chronic bronchitis
how would you manage chronic bronchitis
weight control, harness rather than collar, nebuliser, shower with owner lol
what 4 components are used in treatment of chronic bronchitis
1) bronchodilators
2) anti-inflammatory glucocorticoids- prednisolone
3) antibiotics- if intraceullar bacteria seen on BAL cytology of C and S
4) mucolytics
give 2 bronchodilators used in chronic bronchitis treatment

terbutuline
which mucolytic could be used to increase mucociliary clearance with chronic bronchitis
bromohexine
what is bronchiectasis?
how is it diagnosed
tx?
widening of the bronchi- regional area
dx: radiogrpah and bronchoscopy show dilated bronchi full of mucopurulent material
tx: long term ABs, possible lobectomy
what causes eosinophilic bronchopneumopathy (EBP)?
also known as Pulmonary Infiltrate with Eosinophils (PIE)
hypersensitivity to inhaled allergens or parasites
which respiratory disease would present with coughing, dyspneic dog, coughing on exercise and generally unwell.
on bronchoscopy it shows copious amounts of yellow green mucus, cytology over 25% eosinophils
EBP/ PIE
how would you treat EBP/ PIE
prednisolone +/- fenbendazole for parasite
which parasites can cause respiratory disease in dogs
Oslerus osleri
Crenosoma vulpis- fox lung worm, 4-16mm
which parasites can cause respiratory disease in cats
