[Study of the reasons for a decrease in the inoculability of diphtheria bacteria].

It was shown that the seeding efficacy of diphtheria bacilli depended not only on the state of the epidemic process, but also on the correct methodical approach to the examination. A combination of the qualitative and epidemiological choice of the groups of population for bacteriological examination with the use of blood tellurite media permitted to increase the efficacy of investigations, with a considerable reduction of the number of analyses.
