tuberculosis is an infectious disease that caused by mycobacterium tuberculosis (tb). despite the implementation of free treatment, detection rate of tb remains low. lake of awareness is a main reason for not expressing symptoms in patients. the study aimed to determine the level ofawareness about tb among rural areas of gorgan. this study was cross-sectional research which was conducted in 201...
Determination of seric levels of adenosine deaminase (ADA), an enzyme produced by monocytes/macrophages and lymphocytes, has been used in the diagnosis of human tuberculosis (TB). In the present study, ADA seric activity was evaluated comparatively to the comparative tuberculin test in the diagnosis of bovine tuberculosis. Two hundred fifty-six cattle were classified by origin and by the compar...
BACKGROUND Diagnosis of tuberculous (TB) pleuritis is difficult and better diagnostic tools are needed. New blood based interferon-gamma (IFN-gamma) tests are promising, but sensitivity could be low in HIV positive patients. The IFN-gamma tests have not yet been validated for use in pleural fluid, a compartment with higher level of immune activation than in blood. METHODS The QuantiFERON TB-G...
BACKGROUND Although tuberculosis (TB) is a minor problem in Denmark, severe and complicated cases occur in HIV positive. Since the new M. tuberculosis specific test for latent TB, the QuantiFERON-TB In-Tube test (QFT-IT) became available the patients in our clinic have been screened for the presence of latent TB using the QFT-IT test. We here report the results from the first patients screened....
Background & Objective: Because of uncertainty in interpretation of some tests for diagnosing TB, decision making for the tuberculosis treatment is based on multiple diagnostic tests. This study was conducted to assess the accuracy of Quanti FERON-TB Gold test in tuberculosis diagnosis. Methods: The study was carried out on 30 cases and 46 controls.

A new immunodiagnostic test based on the Mycobacterium tuberculosis-specific antigens CFP-10/ESAT-6(QFT-RD1) has been launched as an aid in the diagnosis of latent tuberculosis (TB) infection (LTBI). The aim of this study was to evaluate this test for the diagnosis of active TB. Eighty-two patients with suspicion of TB and 39 healthy BCG-vaccinated persons were enrolled. Forty-eight had active ...
BACKGROUND Early and effective detection of Mycobacterium tuberculosis (MTB), particularly in smear-negative tuberculosis (TB), is a priority for global TB control. Loop-mediated isothermal amplification with a procedure for ultra rapid DNA extraction (PURE-LAMP) can detect TB in sputum samples rapidly and with high sensitivity and specificity. However, the PURE-LAMP test has not been effective...
