Aspartate transaminase level was significantly increased in intestine of experimentals that received multiple doses of infection. The level of alanine transaminase rose to a significant value in liver of mice infected with multiple doses. Rise of transaminases is correlated with the necrosis (disruption of intestina) hepatic cells in infected mice. Changes and/or the distribution of aspartate transaminase and alanine transaminase with regard to the dosage is discussed.
