FIGURE 6.
The expression of pili islands gene expression in ST17 and ST1 group B streptococcus (GBS) strains from Mayanei Hayeshua Medical Center (MHMC) were analyzed by qRT-PCR analysis. Amounts of each transcript are normalized to rpoB gene and expressed relative to this gene in reference strain ATCC BAA611. The expression level of ATCC BAA611 strain was defined as 1. Columns represent relative mRNA expression level of each gene from each strain. Values are represented as means ± SD (n = 8) from three independent qRT-PCR experiments. Error bar show SD. Asterisk indicates a significant difference (*p < 0.05 by t-test).
