background: tuberculosis (tb) remains as a major cause of death around the world. construction of a new vaccine against tuberculosis is an effective way to control it. several vaccines against this disease have been developed. the aim of the present study was to cloning of tb10.4 gene in pcdna3.1+ plasmid and evaluation of its expression in eukaryotic cells. methods: firstly, tb10.4 fragment wa...

background: the risk of developing tuberculosis is high among chronic hemodialysis patients. the tuberculin skin test (tst) has been in use for diagnosing latent tb, but few data are available on tst in hemodialysis patients. objective: this study was done to identify the tst reactivity and frequency of booster effect in serial tst among hemodialysis patients. methods: a total of 100 patients i...

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...

Mycobacterium marinum is an unusual atypical mycobacterium with low pathogenicity for humans in comparison with Mycobacterium tuberculosis. Among the non-tuberculous mycobacterial pathogens, Mycobacterium marinum is the most common pathogen to cause skin infections. Mycobacterium marinum infection causes chronic cutaneous lesions and in some cases deeper infections such as tenosynovitis, septic...

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...

conclusions the results of this study demonstrated that the p450 cyp141 gene was successfully cloned into a pet26b plasmid vector as an expression vector. in this paper, for the first time in iran, this gene was cloned for more purposes, including the expression and purification of the recombinant cytochrome p450 cyp141 protein. results the cloning of p450 cyp141 gene was confirmed by the enzym...

introduction: development of effective immunodiagnostic methods for detection of mycobacterium tuberculosis infection is crucial. serodiagnostic methods, based on antibody response to specific antigens could provide promising approaches for rapid, economical and easy to perform diagnostic tests which are crucial for tuberculosis (tb) control. in this study, the level of igg antibody responses a...
