Ga(NO₃)₃ inhibits intracellular growth of clinical isolate MC2638 at higher concentrations. THP-1 cells were transformed and infected with clinical isolate MC2638 for 1 h, washed, and cultured for up to 6 days in the presence of different concentrations of Ga(NO₃)₃ as described in Materials and Methods. Ga(NO₃)₃ significantly inhibited intracellular MC2638 (**, P < 0.001) as measured by CFU counting (A) or when results were normalized to the control (B) (*, P < 0.05; n = 4 replicates). The time zero CFU count was 2.2 × 10⁴.
