The antibacterial activity of HU, HA and M-HA against Gram-positive and Gram-negative bacteria.

The growth inhibition of different bacteria after culturing them in HU-, HA-, or M-HA-supplemented media. The data are representative of one of at least three independent experiments. HU, hydroxyurea; HA, hydroxylamine; M-HA, methyl-hydroxylamine; MIC50, 50% inhibitory concentration; MIC100, 100% inhibitory concentration; CC50, 50% cytotoxicity inhibitory concentration; and SI, selectivity index (SI = CC50/MIC50).The antibacterial activity of HU, HA and M-HA against Gram-positive and Gram-negative bacteria.
