Changes in resistance to radiation and heat during sporulation and germination of Clostridium botulinum 33A.
During sporulation, Clostridium botulinum 33A developed resistance to ultraviolet and gamma rays about 2 hr prior to its development of heat resistance. During germination, loss of resistance to heat, ultraviolet radiation, and gamma radiation occurred essentially simultaneously.
