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 ...
The development of new drugs and vaccines directed against Mycobacterium tuberculosis is severely impeded by the slow growth of this organism and the need to work under stringent biosafety conditions. These difficulties pose considerable obstacles when animal studies with M. tuberculosis are performed. We investigated whether a novel approach termed luciferase in vivo expression, using an enhan...
ObjectivesThe first objective of the European Committee on Antimicrobial Susceptibility Testing (EUCAST) subcommittee for antimycobacterial susceptibility testing (AMST), launched in 2016, was to set a reference method determining MICs antituberculous agents, since many protocols are used worldwide and consensus one is needed determination microbiological breakpoints.MethodsDuring 2017 2018, MI...
The growing problems of tuberculosis have led to the search for new anti-Mtb agents from higher plants. The stem bark of Spondias mombin was evaluated for its in vitro activity against Mycobacterium tuberculosis (H37Rv strain). Bioassay-guided fractionation of the methanol extract was carried out by Vacuum Liquid Chromatography (VLC) on Silica gel (230-400 mesh) and purification was done using ...
Mycobacterium tuberculosis (MTB) is the causative agent of tuberculosis. The increasing incidence of multi drug resistance tuberculosis (MDR-TB) and extensively drug resistance tuberculosis (XDR-TB) worldwide highlighted the urgent need to search for alternative antimycobacterial agents. More and more people in developing countries utilize traditional medicine for their major primary health car...
Infectious diseases, such as tuberculosis and invasive mycoses, represent serious health problems. As a part of our long-term efforts to find new agents for the treatment of these diseases, a new series of pyrazine analogs of chalcones bearing an isopropyl group in position 5 of the pyrazine ring was prepared. The structures of the compounds were corroborated by IR and NMR spectroscopy and thei...
