[Serum creatine phosphokinase, GOT, and GPT activity in different types of infectious diseases in monkeys]

An increase in creatine phosphokinase (CPK) activity as well as a decrease in activities of aspartate aminotransferase (AAT) and alanine aminotransferase (ALT) were observed in monkey blood serum under conditions of experimental infection of the animals with dysentery. Contrary to the non-immunized animals, the activity of CPK was increased but the activities of AAT and ALT were unaltered in blood serum of the immunized monkeys. Estimation of the enzymatic activity might be used for diagnosis of experimental dysentery and streptococcal infection.
