conclusions subcutaneous nodules in the absence of a local reaction at the site of bcg vaccination may be the sole manifestation of disseminated bcg disease. case presentation we report on an 11-months-old boy with prolonged fever and diffuse hyperpigmented subcutaneous nodules. due to lymphopenia, oral thrush and severe adverse reaction to bcg vaccination, the possibility of primary immunodefi...

Background: BCG protection is suboptimal and there is significant interest to develop new tuberculosis (TB) vaccines. However, there are significant limitations of the current vaccine evaluation systems in the mouse model. Here, we developed a BCG-challenge rabbit skin model as a new way to evaluate the protective efficacy of selected TB subunit vaccine candidates. Methods: Rabbits were immuniz...

Disseminated mycobacterial infection after bacillus Calmette-Guerin (BCG) vaccination is a very rare disorder, occurring mostly in patients with immunologic deficiency. We report a case of disseminated BCG infection in a 16-month-old girl with severe combined immunodeficiency. Plain radiographs showed multiple osteolytic lesions in the femora, tibiae, humerus, and phalanges. Abdominal sonograph...

Tuberculosis remains a major public health problem around the world. Because the Mycobacterium bovis Bacilli-Calmette-Guerin (BCG) vaccine fails to protect adults from pulmonary tuberculosis, there is an urgent need for improved vaccine formulations. Unlike BCG, recombinant vaccines purified from bacterial expression vectors, as well as naked DNA, require an additional adjuvant. Recent improvem...

By 1926, two French physicians working in Indochina, R. Pons and L. Chastel, have suggested to treat leprosy by subcutaneous injections of bacillus Calmette-Guerin. This treatment appeared efficient since the lepromatous lesions quickly regressed and the Hansen bacillus disappeared from the nasal mucus. These results were quickly confirmed by other authors. They were all more appreciated than, ...

Abstract Tuberculosis (TB) is the leading cause of death in people with HIV (PWH) on or off antiretroviral therapy (ART); thus, new TB vaccine candidates should be evaluated setting HIV. Mycobacterium bovis Bacillus Calmette-Guerin (BCG), live attenuated bacterial given intradermally (ID) at birth, contraindicated PWH. We recently demonstrated that intravenous (IV) delivery BCG elicits superior...

Background: Although the efficacy of Bacillus Calmette-Guerin (BCG) vaccine in the prevention of tuberculosis has been noted consistently, the use of BCG vaccine is not without risk. In this study we aimed to evaluate immunologically, children with complication of BCG vaccination in North of Iran.Materials and Methods: This case-control study began in 30 Jan 2013 and was completed in 2 Jul 2015...

UNLABELLED Pathogenic and nonpathogenic species of bacteria and fungi release membrane vesicles (MV), containing proteins, polysaccharides, and lipids, into the extracellular milieu. Previously, we demonstrated that several mycobacterial species, including bacillus Calmette-Guerin (BCG) and Mycobacterium tuberculosis, release MV containing lipids and proteins that subvert host immune response i...

Bacillus Calmette-Guérin (BCG) is a vaccine used to prevent tuberculosis. It made from live, attenuated strain of Mycobacterium bovis . When injected into the human body, it causes mild infection that produces immunity tuberculosis bacterium. The BCG primarily as preventive measure against in children, and generates special resistance disease. To honor its inventors, French scientists Ca...

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...
