Genetic diversity of the C protein beta-antigen gene and its upstream regions within clonally related groups of type Ia and Ib group B streptococci.

Microbiology (Reading, England) - 1 Mar 2006

Abstract excerpt

C protein beta antigen (Bac), a surface protein of group B streptococci (GBS), is known to concurrently bind the Fc portion of IgA and factor H (FH). The authors' previous work has demonstrated that mRNA expression levels show diversity among clonally related strains containing genes (bac) encoding Bac, with high expression noted in invasive strains. In this study, the bac gene and upstream regions containing...
