    Notes: Summary Late-onset of disturbed vision is a clinical feature of bovine GM1 gangliosidosis. Studies on eight affected calves showed that ocular lesions were confined to the retinae and optic nerves. Myriad tiny white spots were visible by ophthalmic examination of the fundus. These spots were related to protuberances on the vitreal surface caused by distended retinal ganglion cells. The perikaryons of these cells were packed with dense aggregates of membranous cytoplasmic bodies (MCBs). Similar MCBs were present in the perikaryons of amacrine cells in the inner nuclear layer of the retina. Wallerian degeneration was present in the optic nerves. The lesions were compared with those described in gangliosidosis in man, cats, pigs and dogs. It is suggested that examination of the fundus is a useful clinical procedure in the diagnosis of bovine GM1 gangliosidosis.

    Notes: Summary Histoenzymic and ultrastructural alterations in the brains of seven calves with GM1 gangliosidosis are described. A decreased oxidative enzyme activity in neurons was accompanied by an increase in acid phosphatase activity. Membranous cytoplasmic bodies were present in neurons and glia. The periodicity of the membranes was about 5.5 to 6.0 nm. Electron-dense, membrane-bound inclusions were present in perithelial cells. The lesions were compared with those of gangliosidoses in other species.

    Description / Table of Contents: Kurzfassung Die Resultate die bei Studien über die GM1 Gangliosidose von Friesischen Kälbern erreicht wurden, werden unter dem Gesichtspunkt der aktuellen Kenntnisse über angeborene lysosomale Krankeiten überprüft. Die angegriffenen Kälber haben geringe Wachstumsraten and weisen im Alter von ungefähr 3 Monaten Anzeichen von Nicht-Koordination und Blindheit auf. Bei 6 bis 9 monatigen Kälbern führt die Krankheit zunehmend zum Tode. Die Lagerung von GM1 Ganglioside in den Neuronen ist mit einer verminderten Aktivät der Gewebe β-Galaktosidose verbunden. Der Augenschein deutet auf einen rezessiven autosomalen Vererbungsmodus. Die Folgen dieser Befunde auf Diagnosen und Kontrollen werden diskutiert.
    Abstract: Resume Les résultats obtenus par les études sur la GM1 gangliosidose des veaux de race frisonne sont revus sous l'aspect des connaissances présentes sur les maladies lysosomiales innées. Les veaux malades présentent de faibles taux de croissance et des signes de non-coordination et de cécité à l'âge d'environ trois mois. Le taux de mortalité va en croissant de six à neuf mois. Le dépôt de GM1 ganglioside dans les neurons va de pair avec une réduction de l'activité β-galactosidase tissulaire. Il y a lieu de penser qu'il s'agit d'un mode éréditaire autosomal récessif. Les conséquences de ces constatations relatives à la diagnose et au contrôle sont discutées.
    Notes: Abstract The results of studies on GM1 gangliosidosis of Friesian calves are reviewed in the light of present knowledge about inborn lysosomal diseases. Affected calves have poor growth rates and develop signs of incoordination and blindness at about three months of age. The disease is progressive resulting in death at six to nine months of age. Storage of GM1 ganglioside in neurons is associated with reduced activity of tissue β-galactosidase. Evidence is presented suggesting an autosomal recessive mode of inheritance. The implications of these findings relative to diagnosis and control are discussed.
