Control of bovine tuberculosis (TB) in cattle has proven particularly challenging where reservoirs of infection exist in wildlife populations. In Britain and Ireland, control is hampered by a reservoir of infection in Eurasian badgers (Meles meles). Badger culling has positive and negative effects on bovine TB in cattle and is difficult, costly and controversial. Here we show that Bacillus Calm...

Intravesical administration of Bacillus Calmette-Guérin (BCG) is the most effective therapy for superficial transitional cell carcinoma of the bladder although its mechanism of action is not known. To determine if bladder tumors are capable of antigen presentation and thus might interact directly with BCG-specific T-cells, we studied the murine bladder tumor MB49. MB49 (MHC Class II negative) (...

Specific immunity to Rous virus-induced sarcoma (RSL) was investigated by the tube leukocyte adherence inhibition (LAI) assay in rats immunized with Bacillus Calmette-Guérin (BCG). Peritoneal cells from Lewis rats immunized s.c. with BCG gave positive reactions in the tube LAI assay with the antigen prepared from RSL in Lewis rats. Lymph node cells from Lewis rats immunized with BCG had no cyto...

Tuberculosis has great public health impact with high rates of mortality and the only prophylactic measure for it is the Mycobacterium bovis bacillus Calmette-Guérin (BCG) vaccine. The present study evaluated the release of cytokines [interleukin (IL)-1, tumour necrosis factor and IL-6] and chemokines [macrophage inflammatory protein (MIP)-1α and MIP-1β] by THP-1 derived macrophages infected wi...

The vaccine Bacillus of Calmette Guérin (BCG) was originally developed in France as an oral vaccine against tuberculosis. The oral use of this vaccine was replaced by the parenteral route in almost all countries after the Lubeck disaster. In contrast, Brazil retained the oral delivery of the vaccine until the mid-seventies when it was replaced by the intradermal route. This change in route of d...

Granulomatous bacillus Calmette-Guérin (BCG) infection, both localized and disseminated, as a complication of intravesical therapy for transitional cell carcinoma of the bladder is a recognized but highly unusual phenomenon. We report the case of an 89-year-old gentleman with a history of bladder transitional cell carcinoma and subsequent intravesical BCG instillation of the bladder who present...

Pyroptosis is a host immune strategy to defend against Mycobacterium tuberculosis (Mtb) infection. S100A4, calcium-binding protein that plays an important role in promoting cancer progression as well the pathophysiological development of various non-tumor diseases, has not been explored Mtb-infected hosts. In this study, transcriptome analysis peripheral blood patients with pulmonary (PTB) reve...

phosphodiesterases  (pde)  hydrolyse intracellular camp  and  cgmp  to  inactive  5’ monophosphates. decreased level of camp is involved in the pathogenesis of asthma. we and others have shown that phosphodiesterases were upregulated in the lung of allergic rats, and bacilli calmette-guérin (bcg) induced the production of camp in vitro. however, it is unclear how bcg’s effect asthma and whether...

background: tuberculosis is an essential problem for healthcare systems especially in developing countries . all newborns are given bacillus calmette-guérin (bcg) vaccine in iran which is prepared from live bovine tuberculosis bacillus, and is given to protect against tuberculosis. osteomyelitis secondary to bcg vaccination is rare and usually involves epiphysis of long tubular bones. methods: ...

F or many years, public health practitioners have been puzzled by the fact that vaccines developed to fight specific diseases also have nonspecific effects that alter the host response to unrelated infections. In PNAS, Kleinnijenhuis et al. (1) describe part of the immunological mechanism for the nonspecific effects of vaccines: Bacillus Calmette–Guérin vaccine (bacille Calmette–Guérin), which ...
