FIG. 2.

cps regions of serotype 6A and 6B S. pneumoniae. The similarities between the cps loci of a serotype 6A isolate and a serotype 6B isolate with a class 1 cps sequence (both from the Sanger Institute website [http://www.sanger.ac.uk/Projects/S_pneumoniae/CPS/]) and a serotype 6B isolate with a class 2 cps sequence from GenBank (AF24897) were displayed using the Artemis Comparison Tool (http://www.sanger.ac.uk/Software/ACT/). The average, maximum, and minimum percent G+C contents along the cps locus and the locations of the cps genes are shown. The ∼300-bp indel between the wciN and wciO genes is indicated by a striped box. Blocks of red color indicate sequence homology between pairs of sequences.
