Abstract
A nontypeable blood isolate of group B streptococci (GBS) from a patient with endocarditis is suggested to be the nonencapsulated phase of a GBS strain, type III. From the original high-density isolate, a low-density, encapsulated phase was selected by Percoll gradient centrifugation. This phenomenon should be considered before a GBS strain is classified as truly nontypeable.
摘要
一名患有心内膜炎患者的B族链球菌（GBS）不可分型血液分离株被认为是III型GBS菌株的非荚膜期。从原始的高密度分离株中，通过Percoll梯度离心选择出了低密度的荚膜期。在将GBS菌株分类为真正不可分型之前应考虑这种现象。
