The immunogenic proteins MPB64 and MPB80 of Mycobacterium bovis BCG were purified to homogeneity and compared with MPB70. MPB70 and MPB80 showed a similar distribution in substrains of BCG, both being present in high concentrations in culture fluids of BCG substrain Tokyo, BCG Moreau, BCG Russia, and BCG Sweden and in only very small amounts in BCG Glaxo, BCG Tice, BCG Copenhagen, and BCG Paste...

tection against leprosy addressed the question of whether or not BCG was effective against leprosy. BCG vaccine trials against leprosy in South America, Africa, and Asia have demonstrated that the BCG vaccine protects against leprosy (). However the degree of protection conferred by BCG is variable between different populations as is its efficacy in the prevention of tuberculosis (). Repeated d...

Background and Objective: BCG vaccination is used in many countries with a high prevalence of TB to prevent childhood tuberculosis meningitis and miliary disease. Local and systemic sideeffects are associated with BCG vaccine. The most critical reaction is disseminated BCG infection which occurs in mostl...

Intravesical Bacillus Calmette-Guérin (BCG) is considered to be one of the most effective treatments for superficial bladder cancer. Although the mechanisms by which BCG inhibits tumor growth are not known, previous studies have shown that systemic immunization to BCG and the local expression of the immune response in the bladder are associated with a favorable response to BCG therapy. We have ...

PURPOSE OF THE STUDY The purpose of the study was to evaluate the capacity of the surveillance system to respond to the schedule changes in the view of TB vaccination uptake. Complications of Bacillus Calmette-Guerin (BCG) vaccination in Poland are as elsewhere uncommon. In Poland, BCG vaccination with a vaccine produced with Mycobacterium bovis BCG Moreau has been a part of the National Immuni...

The role of TNF-alpha in the control of mycobacterial growth in murine macrophages was studied in vitro. Infection of macrophages from TNF-alpha gene disrupted (TNF-knockout (KO)) mice with recombinant Mycobacterium bovis bacillus Calmette Guérin (BCG) expressing the vector only (BCG-vector) resulted in logarithmic growth of the intracellular bacilli. Infection with BCG-secreting murine TNF-alp...

Two attenuated bacillus Calmette-Guérin (BCG) preparations derived from the same Moreau strain, Copenhagen but grown in Sauton medium containing starch and bacto-peptone (onco BCG, O-BCG), or asparagine (intradermal BCG, ID-BCG), exhibited indistinguishable DNA sequences and bacterial morphology. The number of viable bacilli recovered from spleen, liver and lungs was approximately the same in m...

Immunotherapy with Bacillus Calmette-Guérin (BCG) to treat non-muscle invasive bladder cancer has become an effective and superior alternative to chemotherapy. Intravesical treatment with BCG appears to be relatively safe; however, occasionally BCG infection complicates such treatment. In the present work we describe three patients in whom BCG infection occurred after intravesical BCG therapy. ...

In mice, the early host response to intravenous infection with small doses of dispersed Mycobacterium bovis BCG is controlled by the Bcg gene. After infection with a low dose of M. bovis BCG, Lyt-1+ cells were generated in the spleens of BCG-susceptible mice (Bcgs) in parallel with an increase in the proportion of phagocytic cells. Very few changes occurred in the splenic cell types of BCG-resi...

Tuberculosis (TB) remains a global pandemic despite the use of Bacillus Calmette-Guérin (BCG) vaccine, partly because BCG fails to effectively control adult pulmonary TB. The introduction of novel boost vaccines such as the human Adenovirus 5-vectored AdHu5Ag85A could improve and prolong the protective immunity of BCG immunization. Age at which BCG immunization is implemented varies greatly wor...
