Polyglucosan bodies in the central nervous system of a fox.
Polyglucosan bodies (PGB) in the central nervous system of an old male fox, Vulpes vulpes japonica, without neurological signs were examined by light and electron microscopy, lectin histochemistry and immunohistochemistry. Fox PGB were round, slightly-basophilic and PAS-positive structures. Most of the bodies were situated free in the neuropil. Electron microscopically, fox PGB were composed mainly of branching filaments and electron-dense material. Lectin histochemistry revealed that fox PGB contained mannose and galactose in addition to glucose. Fox PGB were immunoreactive for monoclonal antibodies raised against human polyglucosan. These findings indicate that fox PGB are similar to feline ones.
