Animal model: Ceroidosis (ceroid-lipofuscinosis) in Australian Cattle dogs

Ceroid-lipofuscinosis is described in Australian Cattle dogs. Lesions included storage of ceroid-lipofuscin in most tissues with characteristic ultrastructural inclusion body patterns in neurons and other cells. Dolichol concentration of the affected dog's brain was similar to those in age-matched control dog brains. However, concentrations in brain, liver and kidneys were markedly higher than in a slightly younger dog. Biochemical data including lysosomal enzyme activities exclude other lysosomal storage diseases. The clinical and pathological features of this disorder resemble those of the juvenile Spielmeyer-Vogt type of Batten disease in humans.
