title: Violet mink develop an acute disease after experimental infection with Aleutian disease virus (ADV) isolate ADV SL3.
abstract: Six-Aleutian (aa)-genotype violet mink were infected intraperitoneally with the Aleutian Disease Virus (ADV) bone marrow derived isolate ADV SL3. All animals developed virus-specific antibodies and hypergammaglobulinaemia. Mortality during the fourteen week duration of the infection was 50%. The virus induced (histo)pathological lesions typical for Aleutian Disease. By immunohistochemical examination using a virus capsid-specific monoclonal antibody viral antigen was detected in lymph nodes, spleen, kidneys and once in hepatic Kupffer cells. By Southern blot and in situ hybridization studies with strand-specific RNA probes able to distinguish viral replicative forms from merely sequestered genomic DNA, ADV replication was detected in mesenteric lymph nodes and spleen. In one mink DNA replicative forms were also found in bone marrow cells or mononuclear cells of the peripheral blood, respectively. Only single-stranded viral DNA was detected in liver, kidney, gut and lung of infected animals. From Southern blot hybridization results a different, possibly organ-specific permissiveness of ADV in vivo is suggested.
