Cytomegalovirus infection in a pig in South Africa

An 8-week-old piglet with dyspnoea, bilateral mucopurulent nasal discharge and mouth breathing was euthanased and a necropsy was performed. Apart from histological evidence of diffuse rhinitis, large intranuclear inclusion bodies, pathognomonic for porcine cytomegalovirus infection, were detected within mucous glands on the nasal turbinates. This is the first such case to be diagnosed in South Africa.
