Interferon-Gamma Improves Macrophages Function against M. tuberculosis in Multidrug-Resistant Tuberculosis Patients

Figure 3

Prior to being assayed, MDMs remained without (−) or were treated for 24 h with (+) rhIFN-γ (100 U/mL). Data were obtained from the CFU counts performed on day 0, and the M. tuberculosis growth index was determined based on the ratio of day 3 to day 0. Significant difference is denoted by asterisk (; patients and 10 controls; Mann-Whitney test).
