Veterinary science on the causes, conditions for the spread and extinguishment of communicable diseases of animals (i.e., the law of the epiotic process) and prevention and control techniques.Long before the opening of contagious diseases, some empirical prevention and control techniques were developed. The scientific basis of E. served as bacteriological studies of the end of 19 in. The true prosperity of E. has been achieved following research: L. Paster, R. Koha, I. E. Mechnikov, D. I. Ivanovsky, which has contributed to the opening of animal infectious diseases, scientific foundations have been laid for the creation of specific drugs for diagnosis and prevention of these diseases and for the formation of E. as a scientific discipline. The work of Russian scientists L. S. Zenkovsky, the creator of the first domestic vaccines against the Siberia ulcer, H. I. Gelman, O. I. Calninga, who received Mallein, etc., has had a major impact on the development of E. S. N. Veshlesski, who studied many animal infectious diseases (sap, tuberculosis, brucellosis etc.) made a particularly significant contribution to domestic E. Following the October Revolution 1917, the USSR created an enabling environment for the development of E. The network of veterinary institutions, veterinary research institutions and bacteriological laboratories has grown considerably, and the production of biopreparates has been carried out in numerous biofibraries. Soviet scholars, epiotologs and microbiologists, using the benefits of the socialist system, together with veterinary practitioners, have managed to eliminate many dangerous infectious diseases in our country (chumas and peripneumia of large cattle, sap and others) and to limit the spread of a number of diseases (sybir ulcer, classic pork and other).
The main problems of modern E. are the detailed study of the epiotic process, the development and improvement of measures to prevent and combat animal infectious diseases (pest, plague of cattle, classic plague of pigs, Newcasla and Dr., the unification of zoo-opanthroponesis (bestry, bleach, brucells, tuberculosis, etc.), the determination of the causes of disease
