[LDH activity and isoenzyme spectrum in the leukocytes of cows with catarrhal mastitis and chronic endometritis].

The activity of lactatedehydrogenase (LDH) in the leukocytes of cows affected with mastitis and endometritis was found to drop strongly to the detriment of the aerobic fractions of LDH1 and LDH2. The processes of anaerobic glycolysis in such animals ran more intensely their course. The antibiotic therapy raised the functional activity of the white blood cells.
