[Comparative characteristics of the epidemiology of intestinal coli infection caused by 2d-category Escherichia and of Sonne dysentery]. / Sravnitel'naia kharakteristika épidemiologii kishechnoi koli-infektsii, obuslovlennoi ésherikhiiami 2-i kategorii, i dizenterii Zonne.

The authors present the results of a comparative study of Sonne dysentery and of the intestinal coli infection 0124 and 0151; significant differences in their epidemiology shown were chiefly caused by a different degree of pathogenicity of the causative agents of these diseases. A low degree of escherichia pathogenicity, and, in this connection, dependence of the character of the infection manifestation on the dose of the causative agent indicated food factor of the infection spread to be necessary for the origination of the clinically expressed disease. Epidemiological observations and bacteriological data showed that in diseases of escherichia etiology only those persons who had clinical manifestations of the disease could serve as epidemiologically significant sources of infection. In this connection prophylaxis of the mentioned affection should be primarily based on the intensification of the general sanitary measures.
