The lipopolysaccharide receptors for the mutator bacteriophages Mu, MuhP1, and D108 were investigated with lipopolysaccharide mutants of Salmonella typhimurium LT2. Mu adsorbed only to mutants lacking the terminal O antigen but retaining the main chain sugars of the core; the side chain N-acetylglucosamine was not required. MuhP1 and D108 adsorbed partially to cells with the same receptors but adsorbed well only to cells with shorter lipopolysaccharides of the Rc and Rd1 chemotypes.
利用鼠伤寒沙门氏菌LT2的脂多糖突变体研究了诱变噬菌体Mu、MuhP1和D108的脂多糖受体。Mu仅吸附于缺乏末端O抗原但保留核心主链糖的突变体;不需要侧链N-乙酰葡糖胺。MuhP1和D108部分吸附于具有相同受体的细胞,但仅能很好地吸附于具有Rc和Rd1化学型较短脂多糖的细胞。
