PURPOSE Immunotherapy with Bacillus Calmette-Guerin (BCG) instillation is recommended for high-risk, non-muscle invasive bladder cancer. Bacillus Calmette-Guerin is not effective in advanced tumors, and better alternatives are warranted. Immunostimulating gene therapy with adenoviral vectors expressing CD40 ligand (AdCD40L) has shown efficacy in tumor models. CD40 ligand stimulates systemic imm...
the upstream rpoBF1 but with a DNA uptake sequence (in lower case) that was added at the 5′ end to permit DNA transformation (7). The transformant strain NM05-08 was resistant to rifampin (MIC >32 mg/L), and the sequence of the rpoB gene confirmed the His→Tyr mutation. When compared to the parental isolate (LNP21362), strain NM05-08 showed reduced virulence. Indeed, bacterial loads were similar...
Traditionally, the design of new vaccines directed against Mycobacterium tuberculosis, the most successful bacterial pathogen on the planet, has focused on prophylactic candidates that would be given to individuals while they are still young. It is becoming more apparent, however, that there are several types of vaccine candidates now under development that could be used under various condition...
We report a rare case in a female infant (age, 3.5 months) with primary immunodeficiency (IFN-γ/IL-12 pathway defect) who presented with suppurative lymphadenitis after Mycobacterium bovis BCG vaccination. The strain of M. bovis BCG identified was found to be resistant to isoniazid and rifampin. The patient was treated with a special pharmacological regimen involving isoniazid (in a limited, st...
The molecular fingerprints of 1,349 isolates of Mycobacterium bovis received between 1979 and August 2000 at Agence Française de Sécurité Sanitaire des Aliments (Afssa) have been obtained by spoligotyping. The majority of the isolates (1,266) were obtained from cattle living in France. An apparently high level of heterogeneity was observed between isolates. One hundred sixty-one spoligotypes we...
Western blot analysis showed that the 46-kilodalton (kDa) dimeric protein antigen secreted in large amounts by some daughter strains of Mycobacterium bovis BCG corresponded to protein MPB70 present in long-term culture filtrates of the Japanese substrain. The 46/23-kDa antigen is the most abundant protein in supernatant from a 5-day culture but is masked by leaked products in old culture supern...
Tuberculosis is rising in the developing world due to poor health care, human immunodeficiency virus type 1 infection, and the low protective efficacy of the Mycobacterium bovis BCG vaccine. A new vaccination strategy that could protect adults in the developing world from tuberculosis could have a huge impact on public health. We show that BCG boosted by poxviruses expressing antigen 85A induce...
Introduction: In tuberculosis (TB) endemic regions BCG vaccine is administered at birth in an effort to protect against neonatal tuberculous meningitis. However, this live vaccine facilitates overwhelming systemic infections by otherwise innocuous organisms in infants with cellular primary immunodeficiencies . Case Report: Our case is a seven month old infant who developed abscess at BCG vaccin...
