FIG 4.
Ga(NO3)3 inhibits intracellular M. abscessus growth. THP-1 cells were TPA activated into macrophage-like cells. Cells were then infected with M. abscessus ATCC 19977 and cultured for up to 6 days with or without 25 μM Ga(NO3)3. Panel A shows results expressed in CFU counts, and panel B shows results normalized to the control (no Ga). Growth of intracellular M. abscessus was significantly inhibited in the presence of 25 μM Ga(NO3)3. **, P < 0.01; n = 3 replicates.
