SUMMARY increasing severity of trauma elicited marked differences in both acid and alkaline phosphatases. The former is a lysosomal enzyme; whereas, the latter is a nonlysosomal enzyme. The magnitude of enzymatic responses as a result of trauma was not the same for each enzyme. Acid phosphatase activity increased in the bruised tissue while alkaline phosphatase activity decreased. The bound form of acid phosphatase increased in the bruised tissue, a form of the enzyme absent in normal tissue. The following factors seem to play an important role on the activities of these enzymes in poultry tissues: age of trauma, severity of the bruise and staphylococcal infection. Rates of changes in the enzymatic activities after infection were directly related to the number of organisms in the infecting dose and induced an alteration in the activities of alkaline phosphatase in the bruised tissue from a decreased to an increased value compared to normal level.
