DNA microarray analysis was used to measure mRNA levels present in B. bronchiseptica RB50 compared to mRNA levels present in B. bronchiseptica RB54. Differences in mRNA levels are listed as mean fold-changes ± standard error. Fold-changes were calculated by averaging the data from three biological sample sets. aRecently characterized [24].
