title: Comparative dose-survival curves of representative Clostridium botulinum type F spores with type A and B spores.
abstract: Radiation survival data of proteolytic (Walls 8G-F) and non-proteolytic (Eklund 83F) type F spores of Clostridium botulinum were compared with dose-response data of radiation-resistant type A (33A) and B (40B) spores. Strain Eklund 83F was as resistant as strain 33A, whereas strain Walls 8G-F was the most sensitive of the four strains tested. The methods suggested for computing both an initial shoulder and a D value for the dose-survival curves yielded results comparable to the graphic techniques used to obtain these two parameters.
