| correlation of morphology with viability of mycobacterium leprae. | a concept has been developed in the recent years that the evenly stained 'solid' bacilli are living and the 'non-solid' forms are degenerate and dead. this communication presents the findings in experimental mice inoculated with material containing 1 to 10% solid evenly stained m. leprae and also with material containing 0% solid organisms. there was multiplication of the bacilli in both the groups. quantitatively, the yield also was not significantly different. these fundings do not support the ... | 1976 | 799212 |
| bacillaemia in reactive states of leprosy. | 35 cases of lepromatous and near-lepromatous cases of laprosy in reaction have been investigated for the presence of acid-fast bacilli in blood at the height of the reaction as well as at its subsidence. only 3 cases exhibited bacillaemia during reaction. it is therefore unlikely that dissemination of the disease is accentuated during reaction as commonly believed. further, the immune complexes demonstrated to be circulating during reaction are possibly formed by bacillary products and not by wh ... | 1976 | 799213 |
