Background: Mycobacterium tuberculosis lipid antigens take part in pathogenicity of the bacterium but the response of monocytes/macrophages to these antigens in tubercu-losis is not well known. Objective: The aim of current investigation was to study the M. tuberculosis lipid antigens in tuberculosis pathogenesis. Methods: In the present study M. tuberculosis lipid antigens were extracted. Mono...
Background: Pulmonary TB is still the most common form of the tuberculosis in HIV infected patients with different presentations according to the degree of immunosuppression.

Background: Interferon gamma (IFN-γ), a cytokine produced by a variety of cells is involved in the immune response against M. tuberculosis. It activates the production of other cytokines and molecules that kill mycobacterium. IFN-γ also has diagnostic role in identification of active and latent tuberculosis. Objective: To determine the level of IFN-γ in the blood of TB patients. Methods: Ninety...

Background:In some countries, one of the first and most common manifestations of HIV positive patients is tuberculosis (TB). HIV positive people are prone to other infections such as tuberculosis due to immune deficiency and reduced CD4+ cell count. Although increasing access to antiretroviral therapy has led to a reduction in HIV-related opportunistic infections and mortality, the simultaneous...
