The MTT antibacterial assay is an important method in natural component discovery. Researchers can use the to quickly and efficiently evaluate activity of compounds. aim this research was find a reduce background colour bacterial cell interference when using 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) study effect phytochemicals. This used NZ ‘Hass’ ripe avocado seed ext...

Pyrazinamide (PZA) is a first-line antituberculosis (anti-TB) drug capable of killing nonreplicating, persistent Mycobacterium tuberculosis. However, reliable testing of the susceptibility of M. tuberculosis to PZA is challenging. Using 432 clinical M. tuberculosis isolates, we compared the performances of five methods for the determination of M. tuberculosis susceptibility to PZA: the MGIT 960...

We describe a test which uses the ability of viable cells to reduce 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) to detect resistance to a bactericidal drug, rifampin, in in vitro-cultured Mycobacterium tuberculosis. The assay shows a linear relationship between the number of viable bacteria and the ability to reduce MTT. Dead mycobacteria were unable to reduce MTT. Rifam...

MTT (3-(4,5-dimethyl thiazol-2-yl)-2,5-diphenyl tetrazolium bromide) assay is commonly used to validate the viability of metabolically active cells. The study was conducted to examine and validate the MTT test to assess the sperm viability of Nili-Ravi buffalo bulls and compare the efficiency of the test with the supra-vital staining technique (eosin-nigrosine) and hypo-osmotic swelling test. F...
