Ferret lung infected with canine distemper virus

Fluorescent micrograph showing a section of ferret lung infected with Canine Distemper Virus (CDV). CDV is a common and highly infectious disease that affects ferrets, dogs and foxes among other animals, and is very similar to the measles virus. It is highly symptomatic and causes respiratory problems along with neurological issues, which is where it gets its name; from the French 'destemprer', meaning to disturb. This image shows a region of the lung from an infected ferret. The image is labelled with antibodies to the virus (green), cytokeratin (red)that highlights epithelial tissue, DAPI staining marks the cell nucleus (blue).
