The AB blood group system in wild felids.

The blood type of 131 non-domesticated felids belonging to 26 felid species was surveyed in this study. Based upon a tube hemagglutination assay established for domestic cats, 80% of felids had type-A, 18% type-B, and 2% type-AB blood. Felids in the Puma group and African and Asian golden cats had blood type B, whereas all other species were found to have blood type A. Two cheetahs and one bobcat had type-AB blood. Red cell glycolipids analysed by high performance thin layer chromatography revealed a similar ganglioside pattern in wild cats as reported in domestic cats. Independent of the AB blood group system, incompatible blood crossmatch reactions were detected between different felid groups. In conclusion, wild felids display the same AB-erythrocyte antigens as domestic cats, and the same blood typing procedures can be applied for wild and domestic felids.
