A strain of Mycobacterium bovis BCG that secretes high levels of functional murine monocyte chemotactic protein 3 (BCG(MCP-3)) was developed. Mice vaccinated with BCG(MCP-3) displayed increased lymphocyte migration in vivo and augmented antigen-specific T-cell responses compared to mice vaccinated with BCG alone. The level of protection afforded by BCG(MCP-3) was equivalent to that with control...

Levels of serum antibody to Bacillus Calmette-Guerin (BCG) were determined by solid-phase radioimmunoassays in 48 normal donors and 60 patients with bladder cancer. Of 57 patients enrolled in a randomized prospective controlled trial of BCG immunotherapy, 47 were followed for up to 30 months, thus permitting comparisons of tumor recurrence, delayed cutaneous hypersensitivity responses to purifi...

background: different methods have been used for bcg vaccination. alginate microspheres are useful in delivery of vaccines to the gastrointestinal tract by oral route. objective: to compare the immune response following oral microencapsulated and subcutaneous (sc) route administration of bcg vaccine in balb/c mice. methods: alginate microspheres were produced by an internal emulsification metho...

the (bacille calmette-gue´rin) bcg is widely practiced in many countries in pediatric group and is a part of routine vaccination program at birth in ir. iran for prophylaxis against tuberculosis, but its efficacy is a matter of debate in different geographic and ethnic regions. adverse reactions induced by bcg vaccination ranges from bcg adenitis, osteitis, and cold abscess at vaccination site ...

Bacille Calmette-Guérin (BCG), an attenuated strain of Mycobacterium bovis, is the only vaccine available for tuberculosis (TB) control. However, BCG is not an ideal vaccine and has two major limitations: BCG exhibits highly variable effectiveness against the development of TB both in pediatric and adult populations and can cause disseminated BCG disease in immunocompromised individuals. BCG co...

BACKGROUND Whether the commonly used bacillus Calmette-Guérin (BCG) strains Connaught and Tice confer different treatment responses in non-muscle-invasive bladder cancer (NMIBC) is unknown. OBJECTIVES To compare clinical efficacy, immunogenicity, and genetics of BCG Connaught and Tice. DESIGN, SETTING, AND PARTICIPANTS A prospective randomized single-institution trial with treatment of 142 ...

BACKGROUND BCG vaccination in low prevalence countries is controversial. Most discussions have been done by the comparison of benefit, side effect and cost of BCG vaccination. No discussion has been done on the disadvantage of BCG vaccination from the point of view of loss of sensitivity and specificity of tuberculin test on the diagnosis of LTBI. METHOD Three groups, i.e. the BCG vaccination...

bacillus calmette guerin (bcg) developed by albert calmette and camille guerin in france between 1908 and 1921 contained a live attenuated strain of mycobacterium bovis and was administered worldwide to prevent tuberculosis. bcg vaccination is also administered at birth to all the newborns in iran. disseminated bcg infection after bcg vaccination is rare. here in, we report 2 new cases of disse...

BCG is the only vaccine presently available against tuberculosis but it is estimated to prevent only 5% of the all potentially vaccine-preventable deaths due to Tuberculosis. Keeping these in view the present study has been undertaken to evaluate the efficacy of BCG and the effect of repeat dose of BCG on antimycobacterial humoral response in mouse model. To improve BCG immunogenicity, specific...
