Abstract:
Background. Tuberculosis (TB) is a chronic bacterial disease. Mycobacterium tuberculosis, being the leading member of the MTB complex, is the main cause of tuberculosis worldwide. Tuberculosis is managed with combination of drugs: streptomycin, isoniazid, rifampicin, ethambutol, and pyrazinamide. Over the recent past years resistance against first line antituberculous drugs has emerged rapidly throughout the world resulting in MDR strains. The new threat in the management of MDR-TB is the development of resistance against second line drugs: aminoglycosides, polypeptides, fluoroquinolones, and

Abstract:
We showed previously that susceptibility testing forMycobacterium tuberculosis labeled with fluorescein diacetate could be accomplished rapidly by using flow cytometry. However, safety was a major concern because mycobacteria were not killed prior to flow cytometric analysis. In this study, we developed a biologically safe flow cytometric susceptibility test that depends on detection and enumeration of actively growing M. tuberculosis organisms in drug-free and antimycobacterial agent-containing medium. The susceptibilities of 17 clinical isolates of M. tuberculosis to ethambutol, isoniazid, a

Abstract:
3-Substituted-5-(4-pyridylcarboxamide)tetrahydro-2H-[1,3,5]thiadizine-2-thione derivatives (1-9) were synthesized as derivatives of isoniazid (INH) to overcome the resistance developed with its therapeutic use. The structures were confirmed by their spectral and elemental analyses data. These derivatives revealed higher lipophilicity compared with INH. The antimycobacterial activity of the synthesized compounds and INH was evaluated in vitro against Mycobacterium tuberculosis H37Rv at 6.25 µg/ml in BACTEC 12B medium using the BACTEC 460 radiometric system.

Abstract:
ABSTRACT An optimal assay for high-throughput screening for new antituberculosis agents would combine the microplate format and low cost of firefly luciferase reporter assays and redox dyes with the ease of kinetic monitoring inherent in the BACTEC system. The green fluorescent protein (GFP) of the jellyfish Aequorea victoria is a useful reporter molecule which requires neither substrates nor cofactors due to the intrinsically fluorescent nature of the protein. The gene encoding a red-shifted, higher-intensity GFP variant was introduced by electroporation into Mycobacterium tuberculosis H37Ra

Abstract:
ABSTRACTPyrazinamide (PZA) is a potent first-line agent for the treatment of tuberculosis (TB) with activity also against a significant part of drug-resistantMycobacterium tuberculosisstrains. Since PZA is active only at acid pH, testing for susceptibility to PZA is difficult and insufficiently reproducible. The recommended critical concentration for PZA susceptibility (MIC, 100 mg/liter) used in the Bactec systems (460 and MGIT 960) has not been critically evaluated against wild-type MIC distributions in clinical isolates ofMycobacterium tuberculosis. Using the Bactec MGIT 960 system, we dete

Abstract:
The reliability of the Mycobacteria Growth Indicator Tube (MGIT [BBL]) for rapid drug susceptibility testing of Mycobacterium avium complex (MAC) isolates was evaluated. MICs of amikacin, clarithromycin, clofazimine, ethambutol, and rifabutin were determined by the MGIT system for 16 MAC strains. The results were compared with those obtained by the BACTEC broth macrodilution method. The turnaround times were 6 to 8 days (median, 7 days) for the MGIT and 5 to 7 days (median, 6 days) for the BACTEC system. Agreements with BACTEC system-determined MICs, within ±1 log2 dilution, were 100, 100, 88,
