Figure 4

Scatter plots of average percentage signal intensities relative to the positive control of hly probed ECOR strains and controls from Library on a Slide hybridization. The top plot was based on the 16sRNA probe signal adjusted percentage of hly signal compared to positive control and the bottom plot on the unadjusted percentage of hly signal compared to positive control. Strains with >50% signal intensities were proven positive (i.e. contain hly gene) previously by Southern hybridization. Signal variability of hly containing strains may be due to the variability of hybridizations and/or sequence variations among hly genes.
