Studied was the spread of Salmonella-induced abortions in ewes for a period of 15 years (1970-1984) on the base of the epizootic information available and of the calculation of the index of epizooticity, the index of occurrence, and the coefficient of repeatability (return rate). It was found that the first index, which characterizes the epizootic process with regard to time, was 100 percent in eleven districts of the country. Salmonellosis abortions was invariably observed during the entire period of fifteen years. On the base of the epizootic state the districts are subdivided into five categories which makes it possible to zonate the country's territory with special emphasis on the spreading of Salmonella abortions in ewes.
