摘要
The first recorded cases of the recent epizootic were harbour seals observed at the Danish island of Anholt, 12 April 1988. The disease then spread throughout the sea waters of north-western Europe. The total mortality in Europe up to November 1988, was estimated to be at least 17 000 seals. The mortality rate in Danish-Swedish waters was about 60%. Autopsies including sampling for histology of most organs were performed on 37 harbour seals and 12 grey seals, collected mainly at the Swedish west coast and in the southern Baltic. In most of the harbour seals and in three of the grey seals we found histological changes in the upper and lower respiratory tracts, in the lower urinary tract and in the lymphatic system consistent with those diagnostic of distemper viral infection in the canine. These diagnostic criteria were: presence of intracytoplasmic eosinophilic inclusion bodies of epithelial cells of the trachea and the urinary bladder, interstitial pneumonia, and atrophy of lymphatic organs due to depletion of lymphocytes. Our findings in pathology of a canine distemper-like disease in the seals were presented in late August 1988, together with the Dutch findings in virology by Dr. Osterhaus and collaborators. © 1990.
