Abstract

Serological typing of Group-B streptococci isolated on different occasions during the course of natural intramammary infections revealed no shifts between polysaccharide types, but showed that polysaccharide antigens and the protein Ibc antigen may be lost and regained. Pure X-strains may arise from strains previously typed as IIIX or III, or from non-typeable strains, and possibly from Ibc, Ia and Ib strains as well. Such strains may later revert to their original types.

摘要

对自然发生的乳房内感染过程中不同时间分离出的B组链球菌进行血清学分型,结果显示多糖类型之间没有变化,但表明多糖抗原和Ibc蛋白抗原可能会丢失和重新出现。纯X菌株可能源自先前分型为IIIX或III型的菌株,或源自不可分型的菌株,也可能源自Ibc、Ia和Ib菌株。这些菌株后来可能会恢复为其原始类型。
