Intracellular growth of different Mycobacterium tuberculosis strains within a human osteoblasts (SaOS-2) cells, b human epithelial cells (A549) and c murine alveolar macrophages (MHS). After infection at MOI 9-12, cells were incubated with antibiotics to kill extracellular bacteria. Cells were further cultured in their specific media on 37 °C in 5 % CO2 atmosphere for different time hours to see the growth of different strains in different cell types. After specific time points cells were lysed and plated on 7H11 agar to determine intracellular CFU/ml. Data are the mean (±SD) of three separate experiments. (*) Indicates significant value (P < 0.05)
