Romanyuk Z. 3. Epizootological features and improvement of prophylaxis of leptospirosis of cattle in the farms of Zhytomyr area

3. Object - to study the epizootological peculiarities of leptospirosis of the cattle in the conditions of Zhytomyr region, to improve the methods of prevention. Methods of the research - complex epizootological, hematological, serum, Research - complex epizootological, hematological, serum, biochemical, histological and clinical. Scientific novelty - the epizootological monitoring of leptospirosis of the cattle was carried out on the farms of Zhytomyr region for the last eight years. The practicability of the usage of such caracteristics as activity of aminotransferase (AST, ALT), GGT and the content of carotene in the blood serum for defining of the injuries level of the liver during the development of leptospirosis of the cattle were established.
