title: Further biochemical characterization of chronic Trypanosoma brucei gambiense-Microtus montanus infection.
abstract: Tyrosine aminotransferase (TAT), glutamic-pyruvic transaminase (GPT), glutamic-oxaloacetic transaminase (GOT), and alkaline phosphatase (ALP) were measured in the serum and livers of Microtus montanus infected with Trypanosoma brucei gambiense. Only liver TAT and serum ALP showed significant changes. In addition, blood glucose, pyruvate and lactate, and liver glycogen levels were assayed. All four compounds showed significant changes, strongly suggesting increased glycogen mobilization and increased catabolic activity. Interestingly, the serum ketone levels were very low and no significant changes were observed. These chronically infected animals had an organic aciduria in which pyruvate, lactate, beta-hydroxybutyrate, alpha-ketoglutarate, phenylpyruvate, and p-hydroxyphenylpyruvate were significantly increased. The possible significance of these observations is discussed.
