Salmonella typhimurium Rc902 infected with derepressed ColIb mutants gave rise to changes in the composition of bacterial lipopolysaccharides (LPS). Bacteria carrying ColIbdrd7, derepressed in transfer, exhibited a marked decrease in the content of all 0-side-chain sugars of LPS. Similar effect were found upon the introduction of R64-11, also derepressed in transfer. In LPS of S. typhimurium containing ColIbdrd2, derepressed in colicin synthesis, a decrease of abequose content associated with an increase of glucose level was observed. Bacteria carrying the wild-type ColIb, the revertant of a drd mutant to the wild type, or the non colicinogenic strain resulting from the elimination of ColIbdrd2, showed no changes in the sugar composition of LPS.
感染了去阻遏型ColIb突变体的鼠伤寒沙门氏菌Rc902导致细菌脂多糖（LPS）组成发生变化。携带在转移中去阻遏的ColIbdrd7的细菌，其LPS所有O侧链糖的含量显著降低。引入同样在转移中去阻遏的R64 - 11后也发现了类似的效果。在含有在大肠杆菌素合成中去阻遏的ColIbdrd2的鼠伤寒沙门氏菌的LPS中，观察到阿比可糖含量降低，同时葡萄糖水平升高。携带野生型ColIb、drd突变体回复到野生型的菌株或因消除ColIbdrd2而产生的非产大肠杆菌素菌株，其LPS的糖组成没有变化。
