Abstract
The effects of toxin- and capsule-encoding plasmids on the kinetics of UV inactivation of various strains of Bacillus anthracis were investigated. Plasmids pXO1 and pXO2 had no effect on bacterial UV sensitivity or photoreactivation. Vegetative cells were capable of photoreactivation, but photo-induced repair of UV damage was absent in B. anthracis Sterne spores.
摘要
研究了编码毒素和荚膜的质粒对不同炭疽芽孢杆菌菌株紫外线灭活动力学的影响。质粒pXO1和pXO2对细菌的紫外线敏感性或光复活没有影响。营养细胞能够进行光复活，但炭疽芽孢杆菌斯特恩菌株的孢子中不存在紫外线损伤的光诱导修复。
