The location of type polysaccharides on the cells of reference strains of group-B streptococci of serotypes IV and V and new type candidates NT6 and 7271 was investigated by electronmicroscopy of the bacteria after incubation with homologous type-specific antiserum. A distinct capsular layer was found on the surface of the cells of all these strains. Sialic acid, an integral part of all the conventional type polysaccharides of group-B streptococci, was also detected in all the strains examined.
通过将B族链球菌血清型IV和V的参考菌株以及新型候选菌株NT6和7271与同源型特异性抗血清孵育后进行细菌电子显微镜检查，研究了其多糖在细胞上的定位。在所有这些菌株的细胞表面均发现了一层明显的荚膜层。在所有检测的菌株中还检测到了唾液酸，它是B族链球菌所有传统型多糖的一个组成部分。
