3种细菌芽胞遗传同源性及抗力对比研究

Comparison of Genetic Homology and Resistance of Three Bacillus Spores

比较细菌芽胞的遗传同源性、结构和抗力差异,为炭疽芽胞的替代试验菌的可靠评价提供依据。采用资料检索、生物信息分析、显微镜观察和微生物学技术分析不同芽胞的遗传同源性、超微结构和抗力差异。炭疽芽胞与腊样芽胞的结构和大小相似,生物遗传同源性最近,对热力、UVC和有效氯的抗力相近。腊样芽胞对炭疽芽胞的代表性最好,可以倾向性选用其替代炭疽芽胞进行试验研究。

Genetic homology, structure, and resistance difference of bacillus spores were compared to provide foundation to evaluate the reliability of experimental substitute for Bacillus anthracis spore using data-search, bio-information analysis, microscopic observation, and microbiological technology to analyze the genetic homology, uhrastructure, and resistance difference of different spores. The results showed that the structure and the size of B. anthracis was similar to those of B. cereus, very close in genetic homology, close in the resistance against heat, UVC, and effective chlorine. Therefore, B. cereus had the best representativeness of B. anthracis, and could be used tendentiously and selectively to study their spores.
