The presence of O antigen of the lipopolysaccharide on Klebsiella pneumoniae is responsible for the low transformation frequencies observed. No significant influence of capsular polysaccharide could be observed. This phenomenon was independent of the transformation procedure and plasmid size.
肺炎克雷伯菌脂多糖上O抗原的存在导致了所观察到的低转化频率。未观察到荚膜多糖有显著影响。这种现象与转化程序和质粒大小无关。
