Differential expression in uninfected udder quarters from animals infected with Escherichia coli and Staphylococcus aureus. Preliminary analysis of the microarray data revealed different patterns of gene expression in control quarters from animals infected with Escherichia coli and Staphylococcus aureus. The log normalized intensity values (sample [Cy5]/reference [Cy3]) were plotted for the combined data from control quarters from animals infected with E. coli (EC24T0) and S. aureus (SAT0) using GeneSpring (Agilent). Both plots have a normal-type distribution around 1. EC24T0 have a broader peak of intensity values suggesting a greater range of expression compared to SAT0.
