Subject: [ferrethealth] encephalitis in a mustelid following avian influenza infection
To: ferrethealth@yahoogroups.com
A martin rather than a ferret, and this is an avian influenza H5N1
strain, but the possibility may be one to know about:

Recent outbreaks of disease in different avian species, caused by the
highly pathogenic avian influenza virus (HPAIV), have involved
infection by subtype H5N1 of the virus. This virus has also crossed
species barriers and infected felines and humans. Here, we report the
natural infection of a stone marten (Martes foina) from an area with
numerous confirmed cases of H5N1 HPAIV infection in wild birds.
Histopathological examination of tissues from this animal revealed a
diffuse nonsuppurative panencephalitis with perivascular cuffing,
multifocal gliosis and neuronal necrosis. Additionally, focal necrosis
of pancreatic acinar cells was observed. Immunohistochemically,
lesions in these organs were associated with avian influenza virus
antigen in neurons, glial cells and pancreatic acinar cells. Thus, the
microscopical lesions and viral antigen distribution in this stone
marten differs from that recently described for cats naturally and
experimentally infected with the same virus subtype. This is the first
report of natural infection of a mustelid with HPAIV H5N1.
