DETERMINATION OF THE DIFFERENCES IN RESISTANCE OF CLOSTRIDIUM BOTULINUM TYPES AND STRAINS TO IONIZING RADIATION. Report No. 7 (Progress) for October 1-December 31, 1959

Technical Report ·
OSTI ID:4149919

Ten strains of Cl. botulinum spores were screened for resistance to 1.4 megarad gamma rays in phosphate buffer at pH 7.0. Strain 36A survived in 6 of 10 replicate tubes and appears to be the most radioresistant of 58 strains tested. Strain 37A wse viable in one of 10 replicate tubes. The remaining strains were killed by 1.4 megarad. A toxigenic variant of strain 12885A was somewhat more radioresistant than the nontoxigenic variant. (auth)
