The classical agents (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contain bacterial antigens. Some are endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Their mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy of many biological response modifiers is related to their antigen-specific immunoadjuvanticity.

The host cells take up the DNA, express the antigen, and present it to the immune system in a manner similar to that which would occur during natural infection. This induces humoral and cellular immune responses against the encoded antigens. The vector is called naked DNA because there is no need for complex formulations or delivery agents; the plasmid is injected in saline or other buffers.
CD4-Positive T-Lymphocytes
A critical subpopulation of T-lymphocytes involved in the induction of most immunological functions. The HIV virus has selective tropism for the T4 cell which expresses the CD4 phenotypic marker, a receptor for HIV. In fact, the key element in the profound immunosuppression seen in HIV infection is the depletion of this subset of T-lymphocytes.
Th1 Cells
Subset of helper-inducer T-lymphocytes which synthesize and secrete interleukin-2, gamma-interferon, and interleukin-12. Due to their ability to kill antigen-presenting cells and their lymphokine-mediated effector activity, Th1 cells are associated with vigorous delayed-type hypersensitivity reactions.

Generation of CD8(+) T-cell responses to Mycobacterium bovis and mycobacterial antigen in experimental bovine tuberculosis. (1/2326)

Protective immunity against tuberculosis is considered to be essentially cell mediated, and an important role for CD8(+) T lymphocytes has been suggested by several studies of murine and human infections. The present work, using an experimental model of infection with Mycobacterium bovis in cattle, showed that live M. bovis elicits the activation of CD8(+) T cells in vitro. However, a sonic extract prepared from M. bovis (MBSE) and protein purified derivative (PPDb) also induced a considerable degree of activation of the CD8(+) T cells. Analysis of proliferative responses of peripheral blood mononuclear cells, purified CD8(+) T cells, and CD8(+) T-cell clones to M. bovis and to soluble antigenic preparations (MBSE, PPDb) showed that the responses of all three types of cells were always superior for live mycobacteria but that strong responses were also obtained with complex soluble preparations. Furthermore, while cytotoxic capabilities were not investigated, the CD8(+) T cells were found to produce and release gamma interferon in response to antigen (live and soluble), which indicated one possible protective mechanism for these cells in bovine tuberculosis. Finally, it was demonstrated by metabolic inhibition with brefeldin A and cytochalasin D at the clonal level that an endogenous pathway of antigen processing is required for presentation to bovine CD8(+) cells and that presentation is also dependent on phagocytosis of the antigen.  (+info)

Fluoroquinolone action against clinical isolates of Mycobacterium tuberculosis: effects of a C-8 methoxyl group on survival in liquid media and in human macrophages. (2/2326)

When the lethal action of a C-8 methoxyl fluoroquinolone against clinical isolates of Mycobacterium tuberculosis in liquid medium was measured, the compound was found to be three to four times more effective (as determined by measuring the 90% lethal dose) than a C-8-H control fluoroquinolone or ciprofloxacin against cells having a wild-type gyrA (gyrase) gene. Against ciprofloxacin-resistant strains, the C-8 methoxyl group enhanced lethality when alanine was replaced by valine at position 90 of the GyrA protein or when aspartic acid 94 was replaced by glycine, histidine, or tyrosine. During infection of a human macrophage model by wild-type Mycobacterium bovis BCG, the C-8 methoxyl group lowered survival 20- to 100-fold compared with the same concentration of a C-8-H fluoroquinolone. The C-8 methoxyl fluoroquinolone was also more effective than ciprofloxacin against a gyrA Asn94 mutant of M. bovis BCG. In an M. tuberculosis-macrophage system the C-8 methoxyl group improved fluoroquinolone action against both quinolone-susceptible and quinolone-resistant clinical isolates. Thus, a C-8 methoxyl group enhances the bactericidal activity of quinolones with N1-cyclopropyl substitutions; these data encourage further refinement of fluoroquinolones as antituberculosis agents.  (+info)

Observations on animal and human health during the outbreak of Mycobacterium bovis in game farm wapiti in Alberta. (3/2326)

This report describes and discusses the history, clinical, pathologic, epidemiologic, and human health aspects of an outbreak of Mycobacterium bovis infection in domestic wapiti in Alberta between 1990 and 1993, shortly after legislative changes allowing game farming. The extent and seriousness of the outbreak of M. bovis in wapiti in Alberta was not fully known at its onset. The clinical findings in the first recognized infected wapiti are presented and the postmortem records for the herd in which the animal resided are summarized. Epidemiologic findings from the subsequent field investigation are reviewed, the results of recognition and investigation of human exposure are updated, and recommendations for reduction of human exposure are presented.  (+info)

Molecular markers demonstrate that the first described multidrug-resistant Mycobacterium bovis outbreak was due to Mycobacterium tuberculosis. (4/2326)

We genetically characterized multidrug-resistant Mycobacterium tuberculosis complex strains which caused a nosocomial outbreak of tuberculosis affecting six human immunodeficiency virus (HIV)-positive patients and one HIV-negative staff member (E. Bouvet, E. Casalino, G. Mendoza-Sassi, S. Lariven, E. Vallee, M. Pernet, S. Gottot, and F. Vachon, AIDS 7:1453-1460, 1993). The strains showed all the phenotypic characteristics of Mycobacterium bovis. They presented a high copy number of IS6110, the spacers 40 to 43 in the direct repeat locus, and the mtp40 fragment. They lacked the G-A mutation at position 285 in the oxyR gene and the C-G mutation at position 169 in the pncA gene. These genetic characteristics revealed that these were dysgonic, slow-growing M. tuberculosis strains mimicking the M. bovis phenotype, probably as a consequence of cellular alterations associated with the multidrug resistance. Spoligotyping and IS6110 restriction fragment length polymorphism (RFLP) analysis confirmed that the outbreak was due to a single strain. However, the IS6110 RFLP pattern of the strain isolated from the last patient, diagnosed three years after the index case, differed slightly from the patterns of the other six strains. A model of a possible genetic event is presented to explain this divergence. This study stresses the value of using several independent molecular markers to identify multidrug-resistant tubercle bacilli.  (+info)

Characterization of exochelins of the Mycobacterium bovis type strain and BCG substrains. (5/2326)

Pathogenic mycobacteria must acquire iron in the host in order to multiply and cause disease. To do so, they release abundant quantities of siderophores called exochelins, which have the capacity to scavenge iron from host iron-binding proteins and deliver it to the mycobacteria. In this study, we have characterized the exochelins of Mycobacterium bovis, the causative agent of bovine and occasionally of human tuberculosis, and the highly attenuated descendant of M. bovis, bacillus Calmette-Guerin (BCG), widely used as a vaccine against human tuberculosis. The M. bovis type strain, five substrains of M. bovis BCG (Copenhagen, Glaxo, Japanese, Pasteur, and Tice), and two strains of virulent Mycobacterium tuberculosis all produce the same set of exochelins, although the relative amounts of individual exochelins may differ. Among these mycobacteria, the total amount of exochelins produced is greatest in M. tuberculosis, intermediate in M. bovis, and smallest in M. bovis BCG.  (+info)

Characterization of mannooligosaccharide caps in mycobacterial lipoarabinomannan by capillary electrophoresis/electrospray mass spectrometry. (6/2326)

A new analytical approach based on capillary electrophoresis-electrospray mass spectrometry (CE/ESI-MS) has provided new insight into the characterization of mannooligosaccharide caps from lipoarabinomannans (LAMs), which are key molecules in the immunopathogenesis of tuberculosis. This analytical approach requires oligosaccharide labeling with the fluorophore 1-aminopyrene-3,6,8-trisulfonate (APTS) by reductive amination at the reducing termini. Optimization of the separation and ionization conditions, such as the choice of capillary electrophoresis (CE) electrolyte buffers, is presented and discussed. Anionic separation of the mono and oligosaccharide APTS derivatives was finally achieved with aqueous triethylammonium formate buffer. It was found that in contrast to the triethylammonium phosphate buffer, the triethylammonium formate buffer was appropriate for CE/ESI-MS coupling analysis of APTS-carbohydrate derivatives. In this case, negative ESI-mass spectra of APTS-carbohydrate adducts showed mainly (M-2H)2-pseudomolecular ions and some sequence fragment ions allowing their non-ambiguous structural characterization at the picomolar level. This analytical approach was successfully applied to more complex mixtures of carbohydrates released by mild acid hydrolysis of the lipoarabinomannans from Mycobacterium bovis BCG. The APTS-mannooligosaccharide cap adducts were separated by CE and their structural characterization achieved by CE/ESI-MS analyses. Mannooligosaccharide caps were routinely analyzed by capillary electrophoresis-laser induced fluorescence (CE-LIF) from 50 fmol of lipoarabinomannans with mannosyl capping (ManLAMs) but sensitivity was about 50 times lower using ESI-MS detection.  (+info)

Oxygen depletion-induced dormancy in Mycobacterium bovis BCG. (7/2326)

Gradual depletion of oxygen causes the shift-down of aerobic growing Mycobacterium bovis BCG to an anaerobic synchronized state of nonreplicating persistence.

Different strategies for molecular differentiation of Mycobacterium bovis strains isolated in Sardinia, Italy. (8/2326)

Different genetic markers were used to analyze 22 Mycobacterium bovis strains isolated from cattle in Sardinia and one human isolate. IS6110 DNA fingerprinting differentiated the strains into six patterns, whereas with enterobacterial repetitive consensus sequence primers produced seven clusters. PCR ribotyping followed by digestion with HaeIII and PvuII produced five and seven patterns, respectively. PCR with the (GTG)5 oligonucleotide primer showed the best discriminatory power, generating eight clusters among the strains analyzed.  (+info)

Several groups have demonstrated the use of suicide plasmids for allelic exchange in fast- and slow-growing mycobacteria. The most efficient are those systems using a counterselectable marker; for mycobacteria, workers have successfully used rpsL (36,42), pyrF (26), and sacB(40). The most promising counterselectable system for the slow-growing mycobacteria is sacB, which confers sensitivity to sucrose. Methods using sacB were used for the targeted disruptions of ureC in M. bovis BCG (40) and M. tuberculosis (37) and theerp gene of M. bovis BCG and M. tuberculosis (8).. We decided to construct a new sacB suicidal vector, pYUB657, and test it for the construction of unmarked, in-frame deletion mutants in the slow-growing mycobacteria. In these studies, we saw an opportunity to examine homologous recombination in the mycobacteria from a practical standpoint. The bane of allelic exchange in slow-growing mycobacteria has been the propensity with which these organisms incorporate exogenous DNA into ...

A human challenge model for Mycobacterium tuberculosis using Mycobacterium bovis bacille Calmette-Guerin. - Immunology
BACKGROUND: There is currently no safe human challenge model of Mycobacterium tuberculosis infection to enable proof-of-concept efficacy evaluation of candidate vaccines against tuberculosis. In vivo antimycobacterial immunity could be assessed using intradermal Mycobacterium bovis bacille Calmette-Guérin (BCG) vaccination as a surrogate for M. tuberculosis infection. METHODS: Healthy BCG-naive and BCG-vaccinated volunteers were challenged with intradermal BCG. BCG load was quantified from skin biopsy specimens by polymerase chain reaction (PCR) and culture colony-forming units. Cellular infiltrate was isolated by suction blisters and examined by flow cytometry. Prechallenge immune readouts were correlated with BCG load after challenge. RESULTS: In BCG-naive volunteers, live BCG was detected at the challenge site for up to 4 weeks and peaked at 2 weeks. Infiltration of mainly CD15(+) neutrophils was observed in blister fluid. In previously BCG-vaccinated individuals, PCR analysis of skin biopsy

Role of undecaprenyl phosphokinase in mycobacteriaRole of undecaprenyl phosphokinase in mycobacteria
The family of mycobacteria is composed of pathogenic and apathogenic bacteria. This study was performed with 3 members of this family, the most prominent pathogenic member, Mycobacterium tuberculosis, the causative agent of tuberculosis, the vaccine strain Mycobacterium bovis BCG which was developed by attenuation of the bovine tuberculosis agent Mycobacterium bovis, and Mycobacterium smegmatis which is apathogenic and widely distributed in soil. A key to understanding mycobacteria and, especially, their resistance is to understand the complexity of their cell wall. Peptidoglycan is a major component of the cell wall and the transport of peptidoglycan precursors out of the cytoplasm to the bacterial surface by undecaprenyl monophosphate is central to cell wall synthesis. Therefore, deletion mutants of the undecaprenyl phosphokinase gene (upk) were generated in M. tuberculosis, M. bovis BCG, and M. smegmatis. In the case of M. smegmatis it was shown that a delta upk deletion mutant, as with ...

Few data are available regarding the induction of memory T-lymphocyte responses in cattle following Bacille Calmette Guérin (BCG) vaccination. Studies of the immune response induced by BCG vaccination provide an insight into the basis of antimycobacterial immunity that could be exploited for the development of more effective vaccination strategies. We used autologous dendritic cells (DC) infected with Mycobacterium bovis Bacille Calmette Guérin (BCG) or pulsed with purified protein derivative from M. bovis (PPD-B) or M. avium (PPD-A) to assess responses of CD4+, CD8+ and WC1+ gammadelta TCR+ lymphocytes from BCG vaccinated and nonvaccinated cattle. Mycobacteria-specific CD4+ and CD8+, but not WC1+ gammadelta TCR+, memory T lymphocytes were demonstrated in BCG-vaccinated cattle. CD4+ and CD8+ lymphocytes proliferated and produced interferon (IFN)-gamma in response to BCG-infected or PPD-B-pulsed DC. Proliferative responses were greater for CD4+ than CD8+ lymphocytes, although secretion of IFN-gamma was

Mycobacterium bovis BCG infection severely delays Trichuris muris expulsion and co-infection suppresses immune responsiveness...
We demonstrate that both pathogens are capable of negatively affecting local and systemic immune responses towards each other by modifying cytokine phenotypes and by inducing general immune suppression. T. muris infection influenced non-specific and pathogen-specific immunity to M. bovis BCG by down-regulating pulmonary TH1 and Treg responses and inducing systemic TH2 responses. However, co-infection did not alter mycobacterial multiplication or dissemination and host pulmonary histopathology remained unaffected compared to BCG-only infected mice. Interestingly, prior M. bovis BCG infection significantly delayed helminth clearance and increased intestinal crypt cell proliferation in BALB/c mice. This was accompanied by a significant reduction in systemic helminth-specific TH1 and TH2 cytokine responses and significantly reduced local TH1 and TH2 responses in comparison to T. muris-only infected mice ...

Maternal Knowledge of Tuberculosis and Bacillus Calmette Guerin Vaccination in Pediatric Health Services in KinshasaMaternal Knowledge of Tuberculosis and Bacillus Calmette Guerin Vaccination in Pediatric Health Services in Kinshasa
Introduction: To participate effectively in the fight against tuberculosis (TB), mothers need to have a good knowledge of TB and its prevention. The objective of this study was to evaluate the knowledge of mothers about TB and Bacillus Calmette Guérin (BCG). Methods: This was a cross-sectional survey performed from September to December 2015 in 4 health care facilities of Kinshasa. It concerned mothers of children who received BCG vaccine. The frequencies and chi-square of Pearson were used to report results. Results: A total of 380 couples of the children and their mothers were recruited. The median age of children was 16 months (ranges: 6 days to 59 months); 224 (58.9%) of them received BCG during the period recommended; 62 (16.3%) experienced a side effect. There was a significant association (p = 0.00) between sides effects and the delayed vaccination. The average age of the mothers was 29.3 ± 6.4 years; 352 (92.6%) had heard about TB; 28 (7.4%) never heard about it; 168 (44.2%) knew that TB is a

The genome of Mycobacterium tuberculosis H37Rv includes a homologue of the CRP/FNR (cAMP receptor protein/fumarate and nitrate reduction regulator) family of transcription regulators encoded by Rv3676. Sequencing of the orthologous gene from attenuated Mycobacterium bovis Bacille Calmette-Guérin (BCG) strains revealed point mutations that affect the putative DNA-binding and cNMP-binding domains of the encoded protein. These mutations are not present in the published sequences of the Rv3676 orthologues in M. bovis, M. tuberculosis or Mycobacterium leprae. An Escherichia coli lacZ reporter system was used to show that the M. tuberculosis Rv3676 protein binds to DNA sites for CRP, but this DNA binding was decreased or abolished with the Rv3676 protein counterparts from BCG strains. The DNA-binding ability of the M. tuberculosis Rv3676 protein was decreased by the introduction of base changes corresponding to the BCG point mutations. Conversely, the DNA binding of the BCG Rv3676 proteins from BCG strains

Today it is generally accepted that the Bacillus Calmette-Guerin (BCG) vaccine protects against childhood tuberculosis (TB) but this immunity wanes with age, resulting in insufficient protection against adult pulmonary TB. Hence, one possible strategy to improve the protective efficacy of the BCG vaccine would be to boost in adulthood. In this study, using the mouse model, we evaluated the ability of two new TB vaccine candidates, heat-killed BCG (H-kBCG) and arabinomannan-tetanus toxoid conjugate (AM-TT), given intransally in a novel Eurocine adjuvant, to boost a primary BCG-induced immune response and to improve protection. Young C57BL/6 mice were vaccinated with conventional BCG and, 6 months later, boosted intranasally with adjuvanted H-kBCG or AM-TT, or subcutaneously with BCG. Ten weeks after the booster, mice were challenged intravenously with M. tuberculosis (Mtb) strain H37Rv. In spleens, there was a significant reduction of cfu counts in mice boosted with either H-kBCG or AM-TT vaccines

Tuberculosis vaccine being tested in Phase II trial - Healthcanal.com : Healthcanal.comTuberculosis vaccine being tested in Phase II trial - Healthcanal.com : Healthcanal.com
Scientists have been working on an improved vaccine against the tuberculosis bacterium Mycobacterium tuberculosis for almost 90 years. The Bacillus Calmette-Guérin vaccine (BCG) was developed in the early 20th century and contains attenuated Mycobacterium bovis bacteria, the bovine tuberculosis pathogen that is transmissible to humans. BCG vaccination protects children in most cases against the disease, but not adults. Therefore, the vaccine has not contributed to reducing the global incidence of tuberculosis.. The VPM1002 vaccine, which was developed at the Max Planck Institute for Infection Biology, is based on the BCG vaccine and contains genetically modified Mycobacterium bovis bacteria. A built-in gene makes it easier for the immune cells to recognise the bacteria; the organism can thus protect itself against actual infection with dangerous tuberculosis pathogens. VPM1002 is intended to replace the current BCG vaccine and will be administered to young children to protect them against ...

We used genetic Multi-Locus VNTR Analysis (MLVA) data gathered from surveillance efforts to better understand the ongoing bovine tuberculosis (bTB) epidemic in Northern Irish cattle herds. We modelled the factors associated with Mycobacterium bovis MLVA genotype richness at three analytical scales; breakdown level, herd level, and patch level, and compared the results between dairy and non-dairy production types. In 83% of breakdowns and in 63% of herds, a single MLVA genotype was isolated. Five or more MLVA genotypes were found in less than 3 % of herds. Herd size and the total number of reactors were important explanatory variables, suggesting that increasing MLVA genotype richness was positively related to increases in the number of host animals. Despite their smaller relative size, however, the highest MLVA genotype richness values were observed in non-dairy herds. Increasing inwards cattle movements were important positive predictors of MLVA genotype richness, but mainly in non-dairy settings. The

In this paper we demonstrate a high degree of protection of BCG vaccination against BTB in cattle. The degree of protection of around 75% is comparable to the best results reported over the years in studies where BCG was shown to be protective in cattle (e.g., references 8 and 9). In trials where significant protection has been reported in cattle, protection was characterized by significant reductions in disease-induced pathology and bacterial loads, rather than in sterilizing immunity (8, 9, 18, 52). Our findings confirm these earlier reports.. Although precise correlates of protection await definition, it is generally accepted that control of mycobacterial infections is characterized by the emergence of CD4+ cells producing type 1 cytokines and, in particular, IFN-γ. For example, mice in which the gene for IFN-γ was disrupted are unable to control disease and develop progressive and widespread tissue destruction (12, 22). Furthermore, the central role of IFN-γ in controlling human ...

Pharmaceutical Microbiology: Mycobacterium bovis (M. bovis): reducing the risk of human infection
TB in cattle is caused by the bacterium Mycobacterium bovis (M. bovis). Cattle, buffalo and bison are the natural hosts of M. bovis, but nearly all mammals are susceptible to the infection to a variable degree. The organism also has the capacity to infect and cause TB in humans. However, the risk of infection for the general public remains very low in industrialised countries with long-standing bovine TB control programmes and where pasteurisation of cows milk is either mandatory or commonly practised ...

Zoonotic Mycobacterium bovis : induced tuberculosis in humansZoonotic Mycobacterium bovis : induced tuberculosis in humans
We aimed to estimate the global occurrence of zoonotic tuberculosis (TB) caused by Mycobacterium bovis or M. caprae infections in humans by performing a multilingual, systematic review and analysis of relevant scientific literature of the last 2 decades. Although information from many parts of the world was not available, data from 61 countries suggested a low global disease incidence. In regions outside Africa included in this study, overall median proportions of zoonotic TB of ≤1.4% in connection with overall TB incidence rates ≤71/100,000 population/year suggested low incidence rates. For countries of Africa included in the study, we multiplied the observed median proportion of zoonotic TB cases of 2.8% with the continental average overall TB incidence rate of 264/100,000 population/year, which resulted in a crude estimate of 7 zoonotic TB cases/100,000 population/year. These generally low incidence rates notwithstanding, available data indicated substantial consequences of this disease ...

Between 15 and 20% of patients with newly diagnosed urothelial cancer (UC) of the bladder will have high grade (HG) non-muscle invasive (NMI) disease including carcinoma-in-situ (CIS) and stage Ta and T1 tumors [1]. After transurethral resection of the cancer (TURBT), patients may undergo re-TURBT, but if no muscle invasive (MI) cancer is found most will receive an induction course of 6 weekly intravesical instillations of Bacillus Calmette Guerin (BCG).

BCG infections | PublissoBCG infections | Publisso
The incidence of systemic BCG infection has been reported to present from 3 to 7% [13], [14], [15], [16]. The scope of these complications range from fever, malaise, chills, sweats, weight loss, shortness of breath, and arthralgia, and accounts for one third of cases involving BCG infection [13], [14], [15], [16]. However, less commonly complications such as hepatitis [17], [18], [19], [20], [21], [22], [23], polyarthritis [24], [25], [26], or prosthetic joint infection [27] have also been reported, suggesting high level of clinical suspicion is required addressing atypical infective symptoms following BCG instillation.. Most systemic presentations generally appear earlier, within 8 to 12 weeks following instillation and up to 1 year [13]. Several risk factors for developing BCG systemic infection have been suggested, such as, recent interval to procedures breaching urothelial mucosal integrity, and poor technique during administration [28], [29], [30]. However, the paucity of studies ...

We found evidence that the chromosomal parA and parB genes of M. bovis BCG and M. smegmatis are expressed from multiple promoters. To identify the promoter sequences that regulate the expression of the par genes, we mapped the transcription start sites of the par-mRNAs by primer extension and confirmed the activity of the identified promoters by transcriptional fusions to a fluorescent reporter. We also demonstrated that in M. bovis BCG the parA and parB genes are differentially expressed during the exponential and stationary growth phases.. In all microorganisms studied thus far, plasmid and chromosome-encoded partitioning genes are arranged in an operon. Transcription of the par genes is driven by one (in F and R1 plasmids, P1 prophage and C. crescentus) or two (in S. coelicolor) promoters located upstream of the gene encoding the ATPase (parA or sopA) [5, 7, 13, 15, 32]. The jag, gidB, parA and parB genes of M. bovis BCG and M. smegmatis shared orientation and close spacing, suggesting that ...

Disruption of an antimycobacterial circuit between dendritic and helper T cells in human SPPL2a deficiency. | Nat Immunol;19(9...
Human inborn errors of IFN-γ immunity underlie mycobacterial diseases. We describe patients with Mycobacterium bovis (BCG) disease who are homozygous for loss-of-function mutations of SPPL2A. This gene encodes a transmembrane protease that degrades the N-terminal fragment (NTF) of CD74 (HLA invariant chain) in antigen-presenting cells. The CD74 NTF therefore accumulates in the HLA class II+ myeloid and lymphoid cells of SPPL2a-deficient patients. This toxic fragment selectively depletes IL-12- and IL-23-producing CD1c+ conventional dendritic cells (cDC2s) and their circulating progenitors. Moreover, SPPL2a-deficient memory TH1* cells selectively fail to produce IFN-γ when stimulated with mycobacterial antigens in vitro. Finally, Sppl2a-/- mice lack cDC2s, have CD4+ T cells that produce small amounts of IFN-γ after BCG infection, and are highly susceptible to infection with BCG or Mycobacterium tuberculosis. These findings suggest that inherited SPPL2a deficiency in humans underlies ...

Bovine Tuberculosis is prevalent in Algeria despite governmental attempts to control the disease. The objective of this study was to conduct, for the first time, molecular characterization of a population sample of Mycobacterium bovis strains isolated from slaughter cattle in Algeria. Between August and November 2007, 7250 animals were consecutively screened at the abattoirs of Algiers and Blida. In 260 animals, gross visible granulomatous lesions were detected and put into culture. Bacterial isolates were subsequently analysed by molecular methods. Altogether, 101 bacterial strains from 100 animals were subjected to molecular characterization. M. bovis was isolated from 88 animals. Other bacteria isolated included one strain of M. caprae, four Rhodococcus equi strains, three Non-tuberculous Mycobacteria (NTM) and five strains of other bacterial species. The M. bovis strains isolated showed 22 different spoligotype patterns; four of them had not been previously reported. The majority of M. bovis strains

Intravesical administration of Bacillus Calmette-Guerin (BCG) is a cornerstone of adjuvant treatment for low-grade urothelial carcinoma. Complications from administration are relatively rare and generally evident within one month. Systemic BCG infections are typically diagnosed within 14 days post BCG administration; however, cases have been reported of infections being diagnosed as late as 17 years after treatment. Here, we describe the unusual case of a 55-year-old immunocompetent male who was diagnosed with disseminated BCG infection 3 years after initial adjuvant treatment for urothelial carcinoma.

Effect of skin testing and segregation on the prevalence of bovine tuberculosis, and molecular typing of Mycobacterium bovis,...
In 2002, the prevalence of bovine tuberculosis (tb) among 500 cattle on Holeta Farm, near Addis Ababa, Ethiopia, was 48 per cent, and the farm was divided into positive and negative herds. After three consecutive rounds of skin testing and segregation of skin test-positive and -negative animals, the prevalence of bovine tb was reduced from 14 per cent to 1 per cent in the negative herd in a year. Spoligotyping of 41 isolates from 17 cows gave an identical and unique spoligotype pattern, which can be represented as the binary number 1100000101111110111111100010000000000100000, where 1 indicates the presence of a spacer and 0 represents a loss. This spoligotype pattern had not previously been reported on the Mycobacterium bovis spoligotype database, and it was therefore designated sb1176, Ethiopian M bovis strain 1 (embs1). The variable number tandem repeat (vntr) profile of the strain was 5254*33.1, which differed from the vntr profile of strains reported in Great Britain.. ...

Background:. Each year, more than half a million babies are infected with HIV by mother-to child transmission in developing countries. Many of these babies get sick and develop HIV disease (AIDS) at a very young age. Exposure to other infectious diseases may influence this early progression to AIDS. BCG is a live tuberculosis vaccine made from cow tuberculosis. It is routinely given at birth to most babies, also to babies born to HIV-positive mothers. BCG can cause disease (BCGosis) in HIV-infected babies. More importantly, BCG may also trigger immune responses in the body that lead to the spread of the HIV virus and early progression to AIDS.. Objective(s) and Hypothesis:. The researchers will investigate whether BCG causes progression of HIV by doing a clinical trial: babies born to HIV-positive mothers will be randomly allocated to get the BCG vaccine at birth or at 14 weeks of age. In these 2 groups of babies, the researchers will compare:. ...

Many of these babies get sick and develop HIV disease (AIDS) at a very young age. Exposure to other infectious diseases may influence this early progression to AIDS. BCG is a live tuberculosis vaccine made from cow tuberculosis. It is routinely given at birth to most babies, also to babies born to HIV-positive mothers. BCG can cause disease (BCGosis) in HIV-infected babies. More importantly, BCG may also trigger immune responses in the body that lead to the spread of the HIV virus and early progression to AIDS.. Objective(s) and Hypothesis:. The researchers will investigate whether BCG causes progression of HIV by doing a clinical trial: babies born to HIV-positive mothers will be randomly allocated to get the BCG vaccine at birth or at 14 weeks of age. In these 2 groups of babies, the researchers will compare:. ...

Identification of Mycobacterium bovis Isolates by a multiplex PCRIdentification of Mycobacterium bovis Isolates by a multiplex PCR
Several PCR systems have been developed for the detection of species belonging to the M. tuberculosis complex (MTC). The most commonly used one is based on primers that amplify segments of the IS6110 element, particularly targeting for the 123 bp (2) and 245 bp fragments (7). Another PCR system that yield successful identification of M. bovis isolates is focused on the amplification of a 500-bp DNA fragment inside the RvD1Rv2031c genomic sequence (4). A combination of conventional culture and biochemical techniques is the gold standard method currently used for the identification of M. bovis, which is laborious and time-consuming. In this study we carry out the molecular identification of pure cultures of acid-fast bacilli (AFB) isolated from suggestive bovine tuberculosis lesions. The molecular assay consists of a single-step multiplex PCR (m-PCR), based on two set primers already tested that yet to date have not been combined in a single PCR system. In this study, the assay targets ...

International Conference on Mycobacterium bovis. p. 73. Interpretive Summary: Technical Abstract: In North America, wild elk (Cervus elaphus) and white-tailed deer (Odocoileus virginianus) can be reservoirs for Mycobacterium bovis and are implicated in the maintenance and transmission of tuberculosis to other wildlife, to cattle, and to humans. Current diagnostic tests lack sufficient sensitivity and specificity for accurate detection of infected wildlife populations. In other species, methods which assay the in vitro production of gamma interferon (IFN-gamma) in response to mycobacterial antigens by ELISA or ELISPOT are more sensitive than other tests for tuberculosis. Unfortunately, these assays do not react with many ...

A study of the practical challenges associated with developing a new test for bovine tuberculosis - Nottingham ePrintsA study of the practical challenges associated with developing a new test for bovine tuberculosis - Nottingham ePrints
Bovine tuberculosis, a chronic disease caused by Mycobacterium bovis, is a major economic problem affecting farmers both in the UK and worldwide. In order to prevent and control bovine tuberculosis it is very important to be able to promptly and definitively diagnose infected animals. However, the current diagnostic tools show some limitations which can contribute to cause economic losses and to the transmission of the disease to other animals in a herd, to wildlife and potentially to humans. Therefore, there is an urgent need to have available new diagnostic methods that allow the definitive detection of bovine tuberculosis. In this work, the practical issues associated with the cost-effective production of two diagnostic kits that employ mycobacteriophage (ActiphageTM and ActiphageTM Rapid) were investigated. This technology exploits the ability of bacteriophage to infect live mycobacterial species in a strain specific manner. This technique was originally developed as a tool for the diagnosis ...

This thesis aimed to the identification of immune biomarkers of mycobacterial infection for better diagnosis of tuberculosis (TB) and also focused on new vaccination strategies with a particular emphasis on the immune responses in the respiratory tract using murine models.. Since the lung is the natural habitat for the M. tuberculosis, we reasoned that immune responses detected locally in the lungs would be good correlates of infection (Paper I). Likewise, immune responses induced in the respiratory tract following immunization would be more effective against mycobacterial infection. We showed that cytokines (IL-12, TNF, and IFN-γ) and cytokine receptors (sTNFR1 and sTNFR2) together with specific antibodies in the respiratory tract correlated better with the bacterial burden in the organs. In Paper II, we investigated the role of the BCG vaccination as a priming vaccine in a heterologous prime-boost immunization protocol. The results showed that the neonatal BCG vaccination primed the immune ...

ABSTRACT. Currently, tuberculosis (TB) is a public health problem, is present in all regions of the world and remains one of the most deadly communicable diseases, particularly associated with infection by the human immunodeficiency virus (HIV). Cases of TB Mycobacterium bovis more and more frequent, especially in vulnerable populations. TB caused by M. bovis clinical, radiological and histologically indistinguishable from tuberculosis caused by M. tuberculosis; however, there are some differences that make M. tuberculosis particular. The direct correlation between infection with M. bovis in cattle and human disease has been well documented, but the true prevalence is underestimated. Overall, the proportion of cases of human TB caused by M. bovis is low compared with M. tuberculosis, but its potential in the groups most at risk impact should not be underestimated by the impact on morbidity and mortality.. ...

Mycobacterial lipids have long been known to modulate the function of a variety of cells of the innate immune system. Here, we report the extraction and characterisation of polar and apolar free lipids from Mycobacterium bovis AF 2122/97 and identify the major lipids present in these fractions. Lipids found included trehalose dimycolate (TDM) and trehalose monomycolate (TMM), the apolar phthiocerol dimycocersates (PDIMs), triacyl glycerol (TAG), pentacyl trehalose (PAT), phenolic glycolipid (PGL), and mono-mycolyl glycerol (MMG). Polar lipids identified included glucose monomycolate (GMM), diphosphatidyl glycerol (DPG), phenylethanolamine (PE) and a range of mono- and di-acylated phosphatidyl inositol mannosides (PIMs). These lipid fractions are capable of altering the cytokine profile produced by fresh and cultured bovine monocytes as well as monocyte derived dendritic cells. Significant increases in the production of IL-10, IL-12, MIP-1β, TNFα and IL-6 were seen after exposure of antigen ...

Mycobacterium bovis - RedorbitMycobacterium bovis - Redorbit
Mycobacterium bovis is a slow-growing, aerobic bacterium and the causative agent of tuberculosis in cattle. Similar to M. tuberculosis, M. bovis can jump the species barrier and cause tuberculosis in humans.. It is estimated that M. bovis was responsible for more losses among farm animals than all other diseases combined in the first half of the 20th century. Infection happens after bacterium is ingested. It is generally transmitted to humans via infected milk. Actual human infections are rare generally this is because pasteurization kills the bacteria.. The brushtail possum is the main vector in New Zealand. 40% of cows were infected in the 1930s. The risk of people contracting TB from cattle in Great Britain today is very low.. Badgers were identified as carriers 30 years ago. This caused a major battle between animal conservationists and farmers. Findings indicate that the rising incidence of disease can be reversed through rigid application of cattle-based control measures alone.. Other ...

Following M. bovis infection, a marked in vitro expansion suggests that bovine γδ T cells can mount memory-like responses upon restimulation with mycobacterial Ag (Fig. 1) and (reviewed in Ref. 35). However, to date, a combination of surface markers that effectively identify effector/memory-like subsets of bovine Ag-specific γδ T cells have not been reported. In this study, we show that, compared with CD4 T cells, proliferating M. bovis-specific γδ T cells do not significantly alter CD45RO expression after restimulation with mycobacterial Ags in vitro. Our results agree with reports showing that γδ T cells from human TB patients do not modulate CD45RO expression compared with γδ T cells from noninfected subjects (16, 17). Thus, γδ T cells may acquire a preactivated state early in their development and thus, CD45RO is not useful to identify Ag-experienced γδ T cells. In contrast to CD45RO expression, we found that proliferating γδ T cells from M. bovis-infected cattle ...

Tuberculosis - Free Capstone Project For Students
Tuberculosis (TB) is one of the major infectious diseases caused by Mycobacterium tuberculosis. The World Health organization (WHO) reported that 10.4 million peoples were infected and 1.7 million peoples were died because of TB (WHO, 2016). TB control is difficult due to emergence of multi-drug resistant (MDR) and extremely drug resistant (XDR) TB and HIV-TB co-infections (Kaufmann and Parida 2007). Though, we have one approved TB vaccine Mycobacterium bovis Bacillus Calmette-Geurin (BCG), it gives protection only for childhood not for adulthood.

The failure of current Mycobacterium bovis bacille Calmette-Guérin (BCG) vaccines, given to neonates to protect against adult tuberculosis and the risk of using these live vaccines in HIV-infected infants, has emphasized the need for generating new, more efficacious and safer replacement vaccines. With the availability of genetic techniques for constructing recombinant BCG (rBCG) strains containing well-defined gene deletions or insertions, new vaccine candidates are under evaluation at both the preclinical and clinical stages of development. Since most BCG vaccines in use today were evaluated in clinical trials decades ago and are produced by outdated processes, the development of new BCG vaccines offers a number of advantages that include a modern well-defined manufacturing process along with state-of-the-art evaluation of safety and efficacy in target populations. We provide a description of the preclinical development of two novel rBCGs, VPM1002 that was constructed by adding a modified hly gene

Tuberculosis (TB) kills more than 2 million people worldwide every year. The widely used TB vaccine, Bacille Calmette Guerin (BCG) has variable efficacy and has prompted the search for more effective vaccines. Although significant progress has been made in identifying protective Mycobacterium tuberculosis (Mtb) antigen candidates, our poor understanding of how immune responses mediate protection in the lung remains a major hurdle to successful vaccine design. The major goal of my lab is to define the basic requirements for induction of protective immunity in the lung against pulmonary pathogens such as Mtb. Our past work has described a novel role for the cytokine Interleukin-17 (IL-17) in vaccine-induced immunity against tuberculosis. More recent work from my lab has utilized this information to target and boost lung Th17 responses to improve vaccine-induced immunity against tuberculosis. We have identified that mucosal immunization with Mtb antigen induces a population of lung-resident Th17 ...

A retrospective study (2004-2010) on 24 Mycobacterium bovis strains isolated from wild boars (Sus scrofa) (n=18) and cattle (n=6) in Imperia province (Savona province has been included in the study just in 2006) was performed to detect the prevalence and distribution of antibiotic-resistant strains. Actually, in this area cases of M. bovis infections in wild boar were related to cases in cattle herds due to the overlapping of their respective habitat and pasture areas, suggesting the role of these animals as bio-indicator of the presence of M. bovis in the environment and, in consequence, in farm animals. Susceptibility of all M. bovis strains to antituberculous drugs (isoniazid-INH, rifampicin-RIF, ethambutol-EMB and streptomycin-STR) was detected by proportion method on Lowenstein-Jensen (LJ) medium using recommended critical concentration, while the 6 bovine M. bovis strains were tested by Versatrek method on liquid medium, too.

Frontiers | The Humoral Immune Response to BCG Vaccination | ImmunologyFrontiers | The Humoral Immune Response to BCG Vaccination | Immunology
Bacillus Calmette Guérin (BCG) is the only currently available vaccine against tuberculosis (TB), but it confers incomplete and variable protection against pulmonary TB in humans and bovine TB (bTB) in cattle. Insights into the immune response induced by BCG offer an underexploited opportunity to gain knowledge that may inform the design of a more efficacious vaccine, which is urgently needed to control these major global epidemics. Humoral immunity in TB and bTB has been neglected, but recent studies supporting a role for antibodies in protection against TB has driven a growing interest in determining their relevance to vaccine development. In this manuscript we review what is known about the humoral immune response to BCG vaccination and re-vaccination across species, including evidence for the induction of specific B cells and antibodies; and how these may relate to protection from TB or bTB. We discuss potential explanations for often conflicting findings and consider how factors such as BCG strain

The complete genome sequence of Mycobacterium bovis | PNASThe complete genome sequence of Mycobacterium bovis | PNAS
A group of known antigens affected by deletions from M. bovis is the ESAT-6 family. The ESAT-6 protein was originally described as a potent T cell antigen secreted by M. tuberculosis (20), and belongs to a ,20-membered family that contains other T cell antigens such as CFP-10 and CFP-7. The demonstration of an interaction between ESAT-6 and CFP-10 suggests that other members of the family may also act in pairs, possibly in a mix-and-match arrangement (21). However, six ESAT-6 proteins, encoded by Rv2346c, Rv2347c, Rv3619c, Rv3620c, Rv3890c (Mb3919c), and Rv3905c (Mb3935c) in M. tuberculosis, are missing or altered in M. bovis (Fig. 3). The consequences of their loss are difficult to predict, though they may impact on antigen load either singly or in combination.. The most striking degree of variation in the secretome is the elevated expression of two serodominant antigens, MPB70 and MPB83, in the bovine bacillus (22). MPB83 is a glycosylated cell wall-associated protein, whereas MPB70 is a ...

Macrophage-enriched peritoneal exudate cells from mice infected with Mycobacterium bovis BCG, macrophage-like tumor cells (PU 5-1.8), and peritoneal macrophages propagated in vitro with macrophage growth factor released tumoricidal activity into the culture medium within 2 to 3 h after stimulation with nanogram quantities of bacterial lipopolysaccharide. The cytotoxic activities from each of the macrophage culture supernatants eluted from diethylaminoethyl-Sephacel columns at a sodium chloride concentration of 200 mM exhibited a molecular weight of 50,000 to 60,000 as estimated by gel filtration, were stable at 56 degrees C for 30 min, and were active at a pH range of 6 to 10. A rabbit antiserum directed against serum-derived cytotoxic activity (tumor-necrotizing factor) from BCG-infected and lipopolysaccharide-challenged mice inhibited all of the cytotoxic activities generated in vitro. This suggests that the macrophage-derived cytotoxins are identical with serum-derived cytotoxic factor, which ...
