Guanine-plus-cytosine composition of five group B streptococcal serotypes.

B A Forbes, J J Ferretti.   

Abstract

The percent guanine-plus-cytosine content of deoxyribonucleic acid of each of the five serotypes of group B streptococci was determined by thermal denaturation. The range of guanine-plus-cytosine content was 35.1 to 36.9%, with a mean value of 35.9%. These values suggest a genetic homogeneity to the serotypes of the group B streptococci.
