Targocil exposure of S. aureus does not repress the expression of autolysin genes. S. aureus MW2 was grown in TSB without or with targocil (5 μg/ml), total mRNA was extracted and converted to cDNA, and a qRT-PCR was performed to determine the level of expression of the known autolysin genes (viz., atl, lytM, lytN, and sle1). Error bars show standard deviations from average values from three independent biological replicates.
