Identification of Echinococcus granulosus strains by enzyme electrophoresis.

Hydatid cysts were collected from camels, horses, oxen and sheep in various geographical locations. Extracts from them were compared for electrophoretic forms of glucose phosphate isomerase. All horse cyst extracts had identical zymogram patterns. These differed markedly in mobility from those of cattle and sheep cysts, all of which were identical to one another. Extracts from camels were compared indirectly and may show a third type of pattern.
