Abstract
An outbreak of contagious respiratory disease in mink occurred in October 1984 on the south-east coast of Sweden. High morbidity with coughing, sneezing and dullness was reported. Post mortem examination showed interstitial pneumonia in most examined mink. An avian influenza A virus was isolated and shown to belong to serotype H10N4. Serological studies established that this virus was the most probable cause of the outbreak and also that this new viral infection seemed to be limited to the south-east coast of Sweden.
Keywords: lung, ELISA, contagious pneumonia
Sammanfattning
Ett utbrott av smittsam respiratorisk sjukdom hos mink uppträdde i oktober 1984 i ett begränsat område (Listerlandet) i sydöstra Sverige. Hög morbiditet med hosta, nysningar och andningsproblem rapporterades. Obduktion visade en interstitiell pneumoni av proliferativ typ hos de flesta undersökta minkarna. Ett aviärt influenza A virus isolerades och visades tillhöra serotyp H10N4. Serologiska undersökningar visade att detta virus var den sannolika orsaken till utbrottet samt att denna för mink nya virusinfektion verkade vara begränsad till Listerlandet.
