Primary ciliary dyskinesia in two English Cocker Spaniels

BACKGROUND: Primary ciliary dyskinesia (PCD) is an inherited condition characterised by structural and functional defects of ciliated cells. Ciliated cells are present in several different anatomic locations and PCD can thus cause a variety of clinical signs; however, the predominant clinical signs in dogs are respiratory in nature, most commonly chronic nasal discharge and recurrent lower respiratory tract infections commencing in the neonatal period. CASE REPORT AND CONCLUSION: This report describes two cases of PCD in English Cocker Spaniel puppies presenting with chronic nasal discharge and bronchopneumonia. We describe the use of a minimally invasive technique to collect samples suitable for cilial studies for its diagnosis.
