Figure 3

The presence of putative pathogenicity islands as defined by PCR. Results of PCR (figure 3) and CGH (figure 4) analyses. The genes and GBS strains shaded grey in table 2 are those included in CGH experiments, table 3. Sag0001 encodes dnaA, a positive control for PCR. The NEM316 strain is a positive control. The pNEM316-1 plasmid is located three times in the NEM316 genome, and in figure 1 is represented as 'islands III, VII and VIII'. The strains are divided into three groups: colonizing strains from healthy pregnant women, and strains causing early- and late-onset sepsis in babies; and are sub-divided into those strains for which we have PCR results, and those for which we have PCR and CGH data.
