[Activity of various enzymes in the blood, liver, intestines and kidneys in spontaneous colibacteriosis of piglets].

The purpose of the studies was to determine the activity of enzymes in the serum and pig organs with colibacteriosis in the form of oedema and stomach-intestines disease playing a diagnostic role in the determination of the organ damage degree. Studies were carried out on 29 pigs. The activity of LAP, GPT, GOT, AM, FDPA, Lp, AP and AcP was determined in the serum liver, empty intestines and kidneys of the diseased and control pigs. It resulted from the experiments that in the serum of all the diseased animals the activity of FDPA and GOT was considerably increased and that of AP decreased. So, activity determination does not allow to differentiate both forms of colibacteriosis. AM activity increases only in the serum of oedema pigs. In colibacteriosis of pigs the determination of FDPA activity is the most sensitive enzymatic test. In both diseases the activity of this enzyme increases considerable in the serum and all the studied organs. The activity of the studied enzymes shows that in both forms of collibacteriosis of pigs liver, intestines and kidneys are damaged.
