As the result of epidemiological survey of diphtherial infection, carried out in conformity with the unified methodological recommendations in 21 regions of the RSFSR during 1980-1981, the expediency of such experiment was established. Immunity to diphtheria in children aged up to 14 years was high: children with negative Schick tests constituted 96.9-99.1%. No biological changes in Corynebacterium diphtheriae occurred during the term of observation. Toxigenic C. diphtheriae showed a high level of pathogenicity. The epidemiological survey contributed to a more thorough detection of diphtheria patients and carriers releasing toxigenic C. diphtheriae. The quality of clinical bacteriological diagnosis improved. In rare cases angina with the concomitant carriership of toxigenic C. diphtheriae could be diagnosed with the indispensable serological examination of the patients by Jensen's method.
