Morbillivirus in Common Seals Stranded on the Coasts of Belgium and Northern France During Summer 1998

Sixteen common seals (Phoca vitulina) were stranded on the Belgian and northern French coasts during the summer of 1998. Eleven (10 pups and one adult) were sampled for histopathological, immunohistochemical, serological, bacteriological, parasitological and virological investigations. The main gross findings were severe emaciation, acute haemorrhagic enteritis, acute pneumonia, interstitial pulmonary emphysema and oedema, and chronic ulcerative stomatitis. Microscopical lung findings were acute to subacute pneumonia with interstitial oedema and emphysema. Severe lymphocytic depletion was observed in lymph nodes. Severe acute to subacute meningoencephalitis was observed in one animal. Specific staining with two monoclonal antibodies directed against canine distemper virus (CDV) and phocine distemper virus was observed in a few lymphocytes in the spleen and lymph nodes of three seals. Anti-CDV neutralising antibodies were detected in sera from six animals. Seven of the seals were positive by reverse transcriptase-PCR for the morbillivirus phosphoprotein gene. The lesions observed were consistent with those in animals infected by a morbillivirus, and demonstrated that distemper has recently recurred in North Sea seals. [less ▲]

Isolation of Clostridium perfringens from three neonatal calves with haemorrhagic abomasitis.

Braxy-like disease with sudden death and acute haemorhagic abomasitis was diagnosed in three Belgian Blue calves : one two-day-old and one one month-old calves, in good condition with no clinical signs noted a few hours prior to death, and another two day-old calf, which had shown problems of abomasal dilatation and regurgitation prior to death. Histologically, the abomasal wall were oedematous and emphysematous. A pure and abundant growth of Clostridium perfringens was obtained in anaerobic conditions from the abomasal wall of the three Belgian Blue calves. No bacterial growth was obtained in aerobic conditions. The calf with digestive disorders was also positive for BVD virus by immunofluorescence in the abomasal wall and in the spleen. [less ▲]

Seabirds mortality during the 1992-1993 winter along the Belgian coast

During the 1992-1993 133 seabirds found on Belgian beaches were necropsied. Most frequent species were the guillemot (Uria aalge), the oystercatcher (Haematopus ostralegus), the kittiwake (Rissa tridactyla), the razorbill (Alca torda) and the herring gull (Larus argentatus). The three main observations were, in decreasing order, cachexia, acute and hemorrhagic gastroenteritis, and oil contamination of plumage and intestinal tract. The pelagic origin of seabirds was associated with all 3 observations; oil contamination was associated with acute gastro-enteritis and cachexia and, finally, the immature character was associated with cachexia. A hypothetical mechanism of death would be oiled pelagic seabirds that become cachectic and die of acute gastroenteritis. It is unlikely that seabirds act as a reservoir for bacteria, that were only occasionally identified in our material. Therefore, it appears that infectious agents play a minor role in seabirds stranding. [less ▲]
