Duodenal gangliosidosis in a cat: ultrastructural study.
Ultrastructural changes similar to those seen in gangliosidosis in man were detected in the duodenal mucosa of a cat (cat 1). The N-acetylneuraminic acid concentration was determined from the duodenum of cat 1 and from a clinically normal cat (cat 2). The total amount of gangliosides in the duodenum of cat 1 was 100 times greater than in the duodenum of cat 2 per unit wet weight. The lyophilizate from the intestines of both cats gave a blue-violet color that was regarded as qualitatively positive for N-acetylneuraminic acid determination. In cat 1, membranous cytoplasmic bodies were in all cell types of the duodenal mucosa.
