[Enzyme activity of the tissues of chicks with coccidiosis (Eimeria tenella)]

It has been established that during experimental infection of chickens with Eimeria tenella the decrease in the activity of lactatdehydrogenase of blood serum and the increase of the activity of glutathionereductase in erythrocytes take place. In birds treated with chemcoccid (70 mg/kg of food) the activity of these ferments does not change. The ferment activity of glucose-6-phosphatdehydrogenase does not change in erythrocytes of sick birds while during the treatment with chemcoccid its activity increases. The activity of aspartate aminotransferase decreases in tissues of muscles and increases in liver and brain of sick birds. The activity of alanine aminotransferase decreases in the brain in three and increases in seven days after the infection.
