In vitro activity of garden thyme (Thymus vulgaris L.) chloroform extract against non-tuberculous mycobacteria

This study was carried out to evaluate the antibacterial activity of chloroform (CHL) extract of Thyme vulgaris L. (Lamiaceae). The CHL extract from aerial parts of T. vulgaris exhibited antimicrobial activity against slow growth mycobacteria – SGM (n = 49) and rapid growth mycobacteria – RGM (n = 50) strains isolated from diseased ornamental fish. The MICAV , MIC90, and MIC50 values of CHL extract against to RGM strains were found to be at 194.00, 400, and 200 μg/mL, respectively. The MICAV , MIC90, and MIC50 values of CHL extract against to SGM strains were found to be at 54.59, 100, and 50 μg/mL, respectively. In conclusion, the CHL extract exhibits the activity against non tuberculosis mycobacteria isolated from diseased ornamental fish.
