زمینه و هدف: بیماری سل، نوعی عفونت مشترک بین انسان و دام است که توسط باسیلی به نام مایکوباکتریوم توبرکلوزیس ایجاد می شود. به دلیل وجود آنتی ژن های مشترک با انواع غیر بیماری زای این باکتری، تشخیص دقیق و سریع این بیماری دارای پیچیدگی است؛ لذا یافتن روش تشخیصی سریع با حساسیت و ویژگی بالا در این بیماری حائز اهمیت ویژه است. هدف از این مطالعه ارزیابی عیار سرمی آنتی بادی علیه آنتی ژن نوترکیب esat-6، ...
The use of recombinant attenuated Salmonella vaccine (RASV) strains is a promising strategy for presenting heterologous antigens to the mammalian immune system to induce both cellular and humoral immune responses. However, studies on RASV development differ on where heterologous antigens are expressed and localized within the bacterium, and it is unclear how antigen localization modulates the i...
Background: Mycobacterium (M.) bovis is the agent of bovine tuberculosis (TB) in a range of animal species, including humans. Recent advances in immunology and the molecular biology of Mycobacterium have allowed identification of a large number of antigens with the potential for the development of a new TB vaccine. The ESAT-6 and CFP-10 proteins of M. bovis are important structural and function...
objective(s): an efficient vaccine against tb is an urgent need. tb peptides are safe candidate but they are weak immunogens and needs to be potentiated by adjuvant/delivery systems. the main purpose of the present study was to determine the potential of cht based nps containing esat-6 antigen of m. tuberculosis for inducing mucosal and systemic immune responses after intranasal and subcutaneou...
Objective: To compare the efficacy of the conventional skin test and a novel flow cytometric whole blood assay in the diagnosis of latent tuberculosis infection (LTBI) in patients with rheumatologic diseases evaluated for treatment with tumour necrosis factor (TNF)-α-blocking agents. Methods: Prospective study of 97 consecutively enrolled patients, who were assessed for the presence of LTBI thr...
QuantiFERON®-TB Gold in-tube (QFT-GIT) supernatants may be important samples for use in assessment of anti-tuberculosis (TB) antibodies when only limited volumes of blood can be collected and when a combination of antibody and cytokine measurements are required. These analytes, when used together, may also have the potential to differentiate active pulmonary TB (APTB) from latent TB infection (...
