Comparison of transformation frequency and flanking DNA length in homeologous transformation of <i>H. pylori</i> strains 26695 and J99.

aSource of chromosomal DNA encoding antibiotic resistance used to transform recipient host strain. bMean (±SD) for ten independent transformants. cFor regions in which the inserted DNA was discontinuous, only donor DNA was used to determine the length of flanking DNA. *p<0.05.a. 用于转化受体宿主菌株的、编码抗生素抗性的染色体DNA来源。 b. 10个独立转化子的平均值（±标准差（Standard Deviation，SD））。 c. 对于插入DNA不连续的区域，仅使用供体DNA来确定侧翼DNA的长度。 *p<0.05。
