A–D Scanning electron microscope photographs of strains. Bacteria were grown in 7H9 medium. E Length of H37Rv-WT and H37RvΔRv3737. F Width of H37Rv-WT and H37RvΔRv3737. The difference between the wild type and the mutant was significant by Student’s t test (*p < 0.05; **p < 0.01; ***p < 0.001)Back to article page
