Bacille Calmette-Guérin (BCG) vaccines are widely used, even though estimates of efficacy have ranged from zero to 80%. BCG is a relatively safe vaccine, but it can cause disseminated infection, especially in immunocompromised hosts. Thus, the development of a more reliably efficacious and safer vaccine is important to the control of tuberculosis. The testing of any new vaccine in human populat...

Modulating the host-immune response by the use of recombinant vaccines is a potential strategy to improve protection against microbial pathogens. In this study, we sought to determine whether secretion of murine GM-CSF by the bacillus Calmette-Guérin (BCG) vaccine influenced protective immunity against Mycobacterium tuberculosis. BCG-derived GM-CSF stimulated the in vitro generation of function...

Intravesical Mycobacterium bovis BCG instillation therapy is commonly used to prevent recurrences of carcinoma in situ (CIS) and/or Ta/T1 papillary tumors of the urinary bladder (8). A rare and serious complication associated with BCG treatment of bladder cancer is the development of disseminated BCG disease (1, 6). Current recommendations for bladder cancer patients (being treated with BCG) wh...

Bacillus Calmette-Gu erin (BCG) is the most effective intravesical immunotherapy for superficial bladder cancer. Although generally well tolerated, BCG-related infectious complications may occur following instillation. Much of the current knowledge about this complication comes from single case reports, with heterogeneous diagnostic and therapeutic approaches and no investigation on risk factor...

The mechanism by which human immunodeficiency virus (HIV)-Mycobacterium tuberculosis coinfection facilitates development of HIV-related tuberculosis is poorly characterized. Macaque models of simian immunodeficiency virus (SIV(mac))-Mycobacterium bovis BCG coinfection were employed to explore the pathogenesis of AIDS virus-related tuberculosis. Following BCG coinfection, SIV (SIV)-infected maca...

Tuberculous meningitis (TBM) is a common and serious complication of primary tubercular complex in preschool children in our country. Following exposure to tubercle bacilli, it takes about 6-8 weeks for a primary complex to develop(l). Six to twelve months after the primary infection, tuberculous meningitis, secondary to hematogenous spread, may occur. The commonest age group for tuberculous me...

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...
