Abstract
The ganglioside patterns of erythrocytes from individual horses and cattle were examined. Variations in the ganglioside patterns were found in both horses and cattle. In the erythrocytes of most horses examined, NeuGc-Gal-Glc-ceramide (NeuGc-GM3) was predominant with some 4-O-Ac-NeuGc-Gal-Glc-ceramide (4-O-Ac-NeuGc-GM3), but 3 of 25 horses examined had only NeuGc-GM3 with no 4-O-Ac-NeuGc-GM3. The erythrocytes of various breeds of cattle had a characteristic ganglioside pattern, but they could be divided into 4 types on the basis of the composition of their gangliosides.
