AN EXPERIMENTAL STUDY OF POLYDISPERSE BACTERIAL AEROSOLS. REPORT 3. A STUDY OF DIPHTHERIA BACILLUS AEROSOLS

Abstract

CONCLUSIONS: As a result of a study of the survival rate of diphtheria microbes in an aerosol (beginning with the 3rd minute following spraying and continuing for the next 120 minutes) it was established that it is found in dependence on the evaporation of water: In drops with slowed down evaporation (saliva) the survival rate turned out to be higher than in the rapidly evaporating aqueous particles. The necrosis of microbes in an aerosol increased sharply at a temperature of 35 degrees and at a temperature below zero the viability of all the diphtheria cells was preserved. The highest survival rate for diphtheria microbes was noted in the aerosol during the period when there was a prevalence of large particles. In the presence of small droplet fractions their rate of necrosis increased.
