The Effect of Some of the Chemical Constituents of Tubercle Bacilli on the Protoplasm of Amoeba Dubia
نویسنده
چکیده
1. Protein fractions derived from tubercle bacilli are toxic to the interior of Amoeba dubia but have no action on the plasmalemma. 2. Phosphatide fractions dissolve the plasmalemma but have no effect on the internal cytoplasm. 3. The fatty acid fraction has a marked solvent action on the plasmalemma when brought in contact with the surface of the cell. When injected it may slowly penetrate the cytoplasm to dissolve the contiguous plasmalemma. 4. The polysaccharide fraction has no effect upon the surface membrane or upon the internal cytoplasm of Amoeba dubia.

The first paper (1) of this series described the action of the chlorides of Na, K, Ca, and Mg on the protoplasm of Ameeba dubia as determined by mlcrurgical technique. A study of the effect of other salts of some of these cations forms the basis of this report. 1 Among those tested were a few which are often employed in preparing buffer solutions and some of general physiological interest, part...

متن کاملTHE DETECTION OF Mycobacterium tuberculosis BY PCR IN SPUTUM SAMPLES FROM LONG-TERMTREATED LEPROSY PATIENTS: ASSOCIATIONS WITH SKIN TEST RESULTS AND IMMUNOTHERAPY WITH Mycobacterium vaccae
As part of a series of investigations at Baba Baghi Leprosarium in lran, 44 long-treated leprosy patients were selected for our study. Samples of early morning sputum were obtained from each patient, examined by microscopy for acid-fast bacilli (AFB), and cultured for tubercle bacilli. These tests were negative, but the polymerase chain reaction (PCR) for an insertion sequence believed to b...
