Studies of Mycobacterium leprae, Mycobacterium tuberculosis and Nocardia caviae in comparison with each other and with other Mycobacterium and Nocardia species were performed on the basis of antigen 21 intramolecular heterogeneity. Three different antisera were used: rabbit anti-Mycobacterium smegmatis antiserum, rabbit anti-Nocardia asteroides antiserum, and a lepromatous serum pool. With refe...
mendelian susceptibility to mycobacterial diseases (msmd) is a rare inheritance syndrome, characterized by a disseminated infection with mycobacterium in children following bcg vaccination at birth. regarding the vaccination program in iran, it may consider as a public health problem. the pathogenesis of msmd is dependent on either insufficient production of ifn-gamma (γ) or inadequate response...
The ability of 17 recombinant mycobacterial proteins, native antigen 85 complex, lipoarabinomannan (LAM), and Mycobacterium tuberculosis lysate to detect antibody responses induced by bacille Calmette-Guérin (BCG) vaccination and active tuberculosis infection were studied in enzyme-linked immunosorbent assays. Only LAM-reactive serum immunoglobulin G responses were significantly increased in bo...
An effective host immune response to mycobacterial infection must control pathogen dissemination without inducing immunopathology. Constitutive overexpression of mycobacterial heat shock protein (myHsp70) is associated with impaired bacterial persistence, but the immune-mediated mechanisms are unknown. We found that myHsp70, in addition to enhancing antigen delivery to human dendritic cells, si...
Split anergy represented by delayed-type hypersensitivity skin reaction to tuberculin, but not to leprosin, is known to occur in a distinct proportion of leprosy patients. The mechanism was originally attributed to Mycobacterium leprae-specific suppression of T cells toward common mycobacterial antigens. This study ascertained an alternative explanation, attributing the phenomenon to selective ...
Most cases of mycobacterial lymphadenitis in children are caused by non-tuberculous mycobacteria, previously called the atypical mycobacteria. It is important to differentiate non-tuberculous mycobacterial lymphadenitis from tuberculous lymphadenitis as the treatment is different. We reviewed 19 children (12 girls and seven boys) with non-tuberculous mycobacterial lymphadenitis to define likely...
