An insertion mutant of gtcA, responsible for serotype-specific glycosylation of the cell wall teichoic acid in serotype 4b strains of Listeria monocytogenes, was also resistant to both Listeria genus- and serotype 4b-specific phages. The sugar substituents on teichoic acid appeared essential for the adsorption of phages A500 (serotype 4b specific) and A511 (Listeria genus specific) to serotype 4b L. monocytogenes.
gtcA的一个插入突变体负责单核细胞增生李斯特菌4b血清型菌株细胞壁磷壁酸的血清型特异性糖基化,它对李斯特菌属特异性噬菌体和4b血清型特异性噬菌体均具有抗性。磷壁酸上的糖取代基似乎是噬菌体A500(4b血清型特异性)和A511(李斯特菌属特异性)吸附到4b血清型单核细胞增生李斯特菌上所必需的。
