Project description:A whole genome PCR amplicon DNA microarray for B. mallei were fabricated as previously described . Total RNA was isolated from in vitro cultures in LBG medium of B. mallei ATCC 23344, FMH, and JHU. The OD600 of the samples at harvest were all 0.55. The RNAs from FMH and JHU were labeled and hybridized to the array using the ATCC 23344 RNA as the reference using protocols as described. Flip-dye replicates were performed for all analyses. Two B. mallei ATCC 23344 samples grown to an O.D.600 of 1.0 on separate days and total RNA was extracted. These RNA samples were hybridized against each other as a control for the JHU vs. ATCC 23344 hybridization and the FMH vs. ATCC 23344 hybridization.
