Drug resistance (especially multiple drug resistance) in Mycobacterium tuberculosis makes global concerns in treatment and control of tuberculosis. Rapid diagnosis of drug resistant strains of the bacteria has vital importance in the prognosis of the disease. The aim of this study was to identify the mutations responsible for drug resistance in Mycobacterium tuberculosis strains derived from pa...

background: mycobacterium bovine, as the etiology of bovine tb, involves human in some cases and with mycobacterium tuberculosis are regarded as global health problems. the aim of this study was to extract and compare protein profile of these strains in order to achieve effective biomarkers for diagnosis and the vaccine components. materials and methods: first, the clinical samples were culture...
INTRODUCTION Sarcoidosis is a multisystem granulomatous disorder characterized pathologically by the presence of non-caseating granulomas in involved tissues. Depressed cellular immunity predisposes patients to infections with certain intracellular organisms, mostly fungi, Mycobacterium tuberculosis and Nocardia species. As these infections are mainly insidious and difficult to differentiate fr...
Tuberculosis continues to be a global health threat, making bicyclic nitroimidazoles an important new class of therapeutics. A deazaflavin-dependent nitroreductase (Ddn) from Mycobacterium tuberculosis catalyzes the reduction of nitroimidazoles such as PA-824, resulting in intracellular release of lethal reactive nitrogen species. The N-terminal 30 residues of Ddn are functionally important but...
Abstract Tuberculosis is one of the main health care problems worldwide, so that one third of world population are contaminated with Mycobacterium tuberculosis. It causes 3.1 million deaths annually, therefore, controlling tuberculosis is one the priorities of the world health organization. To control tuberculosis, identifying sources of infection is very important. Patients with active tube...
miliary tuberculosis (tb) is due to hematogenous spread of mycobacterium tuberculosis. clinical manifestations are nonspecific and protean, depending on the predominant site of involvement.we evaluated the clinical manifestations of 15 patients with miliary tb. the diagnosis of miliary tuberculosis was based on the identification of miliary nodules on chest radiography and one of the three foll...
the breast tuberculosis (tb) is an extremely rare manifestation for the reason that mammary cells offer great resistance to the survival and multiplication of mycobacterium infection. the diagnosis is difficult because of nonspecific clinical and radiological findings. it is usually suspected in a multiparous, reproductive woman. we report three cases of tubercular infection of breast confirmed...
In response to stresses, Mycobacterium cells become dormant. This process is regulated by the DosR transcription factor. In Mycobacterium tuberculosis, the dormancy regulon is well characterized and contains the dosR gene itself and dosS and dosT genes encoding DosR kinases, nitroreductases (acg; Rv3131), diacylglycerol acyltransferase (DGAT) (Rv3130c), and many universal stress proteins (USPs)...
Twenty-one strains of Nocardia amarae and marker cultures of Mycobacterium, Nocardia, Rhodococcus and the 'aurantiaca' taxon were subjected to numerical phenetic analyses using 92 unit characters. The data were examined using the simple matching (SSM), Jaccard (SJ) and pattern (DP) coefficients and clustering was achieved using the unweighted average linkage algorithm. Neither cluster nor aggre...
