| Abstract: | ABSTRACT. Agarose gel electrophoresis was used to identify metabolic enzymes in Babesia bovis and B. bigemina. Glutamate dehydrogenase, lactate dehydrogenase, glucose phosphate isomerase, and hexokinase were identified in B. bovis- and B. bigemina-infected erythrocytes and B. bovis merozoite preparations. A specific electrophoretic mobility was observed for each enzyme. Malate dehydrogenase, glucose 6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, and adenylate kinase were only detected in normal erythrocyte preparations. Inter-species, but not intra-species, variation was noted when comparing electrophoretograms of both species. Kinin-activating activity was not detected in B. bovis-infected erythrocyte or merozoite preparations at pH 4.2 or 7.6. |
