introduction: tuberculosis (tb) caused by mycobacterium tuberculosis remains a major worldwide health problem. the only tb vaccine currently available is anattenuated strain of mycobacterium bovis termed bacillus calmette -guerin (bcg).the efficacy of bcg remains controversial. mycobacterium secretory proteins are generally considered important antigens for protection against tb. a major protei...

What methods would you choose apart from purified protein derivative (PPD) skin test and culture for acid-fasting bacilli (AFB) to make a clinical diagnosis of pulmonary tuberculosis (TB) in an aged patient with possible TB? These are two cases TB, that occurred persistent low-grade fever, fatigue anorexia due mild toxemia tuberculosis. A final was established on the basis toxemia(low-grade fev...

Tuberculosis is a common disease in India. Mantoux test is used in children for diagnosis of tuberculosis. Seibert first prepared the purified protein derivative (PPD) from heat-concentrated old tuberculin by precipitating protein initially with trichloroacetic acid(l). PPD when diluted is adsorbed by glass and plastic surfaces. To minimize this a small amount of detergent. Tween-80, is added t...

Tuberculin purified protein derivative (PPD) has been prepared by seven different precipitation methods from culture filtrate of Mycobacterium tuberculosis var. hominis. It was found to contain 48 to 99% tuberculoprotein, depending on the method of precipitation. The remaining percentage is represented by nucleic acid, polysaccharide, and ash. Activation analysis on tuberculin PPD and on tuberc...

  Objective(s): According to the occupationally risk of infection in staff workers who have direct contact with mycobacterium species, we investigated their immunological parameters and compared with healthy purified protein derivative (PPD) negative volunteers.   Materials and Methods : We investigated 20 PPD positive volunteers working at Tuberculin Unit of Razi Vaccine and Serum Research Ins...

We report on the measurement of saliva anti-Purified Protein Derivative sIgA and 38kDa antibodies from 127 children, of whom 31 were strong tuberculosis suspects and 96 were healthy contact children. The results concerning the percentage of children with antibody reactivity to PPD and 38kDa antigens showed that, of these 2 antigens, 38kDa induced higher reactivity in patients positive and negat...

Materials and methods Thirty-seven JIA patients under anti-TNF treatment were enrolled to the study. Chest-X rays, purified protein derivative (PPD) tests, clinical histories and physical examinations were reviewed retrospectively. If PPD was above 10 mm in a patient with one BCG vaccination, family screening, cultures and if needed thorax computerized tomography were obtained and isoniazid pro...

Lymphocytes from Mycobacterium bovis-sensitized and normal cattle were cultured in round- and/or flat-bottom microtiter plates and stimulated with M. bovis purified protein derivative (PPD) tuberculin. Blastogenic responses of lymphocytes from M. bovis-sensitized cattle to PPD cultured in round-bottom plates were significantly greater than those of lymphocytes cultured in flat-bottom microtiter...

objective(s): according to the occupationally risk of infection in staff workers who have direct contact with mycobacterium species, we investigated their immunological parameters and compared with healthy purified protein derivative (ppd) negative volunteers.   materials and methods : we investigated 20 ppd positive volunteers working at tuberculin unit of razi vaccine and serum research insti...

The method used to produce "Connaught" tuberculin purified protein derivative (PPD) is described. The tuberculin PPD for the multiple-puncture method was shown to be stable for at least 24 months at 5 C; tuberculin PPD for the intracutaneous method was shown to be stable at 5 C and 24 C for a period of 18 months in the presence of Tween 80. Evans blue or brillant vital red was added to tubercul...
