Thermal Death Point: I. Spores of Clostridium Tetani

Abstract

It was our purpose to determine the factors that control the resistance of the spores of Clostridiumn tetani to heat. More specifically, it was to study, first, the effect of heat on the spores of C1. tetani in the presence and in the absence of moisture; second, the effect of several variants that might affect the thermal death time under moist conditons, such as the hydrogen ion concentration of the suspending liquid, the effect of organic matter at different hydrogen ion concentrations, and finally the effect of sodium chloride on the thermal death time of the spores of Cl. tetani. A brief outline of the work that has been done to the present time on the resistance of the spores of C1. tetani to heat follows:
