Previous work showed that C. perfringens spores lacking the majority of alpha/beta-type small, acid-soluble spore proteins (SASPs) (termed alpha(-) beta(-) spores) exhibit greatly decreased resistance to moist heat and UV radiation. The current study demonstrated that these alpha(-) beta(-) spores had reduced resistance to hydrogen peroxide, hydrochloric acid, nitrous acid and formaldehyde. These results clearly demonstrate the important role of alpha/beta-type SASPs in the resistance of C. perfringens spores to chemicals.
先前的研究表明，缺乏大多数α/β型小酸溶性芽孢蛋白（SASP）的产气荚膜梭菌芽孢（称为α（-）β（-）芽孢）对湿热和紫外线辐射的抗性大大降低。当前的研究表明，这些α（-）β（-）芽孢对过氧化氢、盐酸、亚硝酸和甲醛的抗性降低。这些结果清楚地证明了α/β型SASP在产气荚膜梭菌芽孢对化学物质抗性中的重要作用。
