Microarray Analysis of Toxicogenomic Effects of Sodium Hypochlorite on Mycobacterium bovis BCG. Mycobacterium tuberculosis variant bovis BCG str. Pasteur 1173P2

In the present study, we employed Affymetrix Mycobacterium bovis BCG GeneChip arrays to investigate the dynamics of global gene expression profiles during the cellular response of Mycobacterium bovis BCG to Sodium Hypochlorite, which involved initial growth inhibition and metabolism. Keywords: Transcriptome study Overall design: We conducted three independent microarray experiments (biological replicates) in the absence (control) and the presence (experimental) of Sodium Hypochlorite. We calculated fold change as the ratio between the signal averages of three untreated (control) and three Sodium Hypochlorite-treated (experimental) cultures for 0, 10 and 20 min exposures.
