Ethionamide has emerged as an alternative to ethambutol for the treatment of tuberculous meningitis (TB meningitis). Here, we show that ethionamide- and ethambutol-containing first-line TB regimens achieved similar bactericidal activities in brain tissues and reduction in neuroinflammation in a mouse model of TB meningitis. However, ethionamide, but not ethambutol, achieves brain concentrations above the minimum inhibitory concentration for Mycobacterium tuberculosis.

Causative Organism
The primary infectious agent causing tuberculosis is Mycobacterium tuberculosis, a slow-growing, acid-fast, aerobic rod that exhibits sensitivity to heat and ultraviolet light. Instances of Mycobacterium bovis and Mycobacterium avium contributing to the development of TB infection are rare.
