Pneumocystosis associated with canine distemper virus infection in a mink.

Abstract

An adult mink from a farm experiencing 100% mortality in affected animals was submitted for diagnostic examination. Clinical history included signs of respiratory disease, oculonasal discharge, and thickening of footpads. Canine distemper virus and Pneumocystis carinii were identified in lung tissue, suggesting immunosuppresion and secondary infection due to morbillivirus disease.
