ip-10 is a sensitive biomarker of antigen recognition in whole-blood stimulation assays used for the diagnosis of mycobacterium bovis infection in african buffaloes (syncerus caffer). | african buffaloes (syncerus caffer) are maintenance hosts of mycobacterium bovis, the causative agent of bovine tuberculosis. they act as reservoirs of this infection for a wide range of wildlife and domestic species, and the detection of infected animals is important to control the geographic spread and transmission of the disease. interferon gamma (ifn-γ) release assays (igras) utilizing pathogen-derived peptide antigens are highly specific tests of m. bovis infection; however, the diagnostic ... | 2015 | 26108287 |
nkg2d is a key receptor for recognition of bladder cancer cells by il-2-activated nk cells and bcg promotes nk cell activation. | intravesical instillation of bacillus calmette-guérin (bcg) is used to treat superficial bladder cancer, either papillary tumors (after transurethral resection) or high-grade flat carcinomas (carcinoma in situ), reducing recurrence in about 70% of patients. initially, bcg was proposed to work through an inflammatory response, mediated by phagocytic uptake of mycobacterial antigens and cytokine release. more recently, other immune effectors such as monocytes, natural killer (nk), and nkt cells ha ... | 2015 | 26106390 |
genetics of mycobacterial arabinogalactan and lipoarabinomannan assembly. | the cell wall of mycobacterium tuberculosis is unique in that it differs significantly from those of both gram-negative and gram-positive bacteria. the thick, carbohydrate- and lipid-rich cell wall with distinct lipoglycans enables mycobacteria to survive under hostile conditions such as shortage of nutrients and antimicrobial exposure. the key features of this highly complex cell wall are the mycolyl-arabinogalactan-peptidoglycan (magp)-based and phosphatidyl-myo-inositol-based macromolecular s ... | 2014 | 26104198 |
age at mycobacterium bovis bcg priming has limited impact on anti-tuberculosis immunity boosted by respiratory mucosal adhu5ag85a immunization in a murine model. | tuberculosis (tb) remains a global pandemic despite the use of bacillus calmette-guérin (bcg) vaccine, partly because bcg fails to effectively control adult pulmonary tb. the introduction of novel boost vaccines such as the human adenovirus 5-vectored adhu5ag85a could improve and prolong the protective immunity of bcg immunization. age at which bcg immunization is implemented varies greatly worldwide, and research is ongoing to discover the optimal stage during childhood to administer the vaccin ... | 2015 | 26098423 |
spray dried aerosol particles of pyrazinoic acid salts for tuberculosis therapy. [corrected]. | tuberculosis is the most serious infectious disease caused by a single organism, mycobacterium tuberculosis (mtb). the standard of care is a protracted and complex drug treatment regimen made more complicated and of longer duration by the incidence of multiple and extensively drug resistant disease. pulmonary delivery of aerosols as a supplement to the existing regimen offers the advantage of delivering high local drug doses to the initial site of infection and most prominent organ system involv ... | 2015 | 26098136 |
using a prime and pull approach, lentivector vaccines expressing ag85a induce immunogenicity but fail to induce protection against mycobacterium bovis bacillus calmette-guérin challenge in mice. | although bacillus calmette-guérin (bcg) is an established vaccine with excellent efficacy against disseminated mycobacterium tuberculosis infection in young children, efficacy in adults suffering from respiratory tuberculosis (tb) is suboptimal. prime-boost viral vectored vaccines have been shown to induce effective immune responses and lentivectors (lv) have been shown to improve mucosal immunity in the lung. a mucosal boost to induce local immunogenicity is also referred to as a 'pull' in a pr ... | 2015 | 26095282 |
infection of a549 human type ii epithelial cells with mycobacterium tuberculosis induces changes in mitochondrial morphology, distribution and mass that are dependent on the early secreted antigen, esat-6. | pulmonary infection by mycobacterium tuberculosis (mtb) involves the invasion of alveolar epithelial cells (aecs). we used mitotracker red(®) to assess changes in mitochondrial morphology/distribution and mass from 6 to 48 h post infection (hpi) by confocal microscopy and flow cytometry in mtb-infected a549 type ii aecs. during early infection there was no effect on mitochondrial morphology, however, by 48 hpi mitochondria appeared fragmented and concentrated around the nucleus. in flow cytometr ... | 2015 | 26092385 |
bcg vaccines. | bcg is the collective name for a family of live attenuated strains of mycobacterium bovis that are currently used as the only vaccine against tuberculosis (tb). there are two major reasons for studying the genome of these organisms: (i) because they are attenuated, bcg vaccines provide a window into mycobacterium tuberculosis virulence, and (ii) because they have provided protection in several clinical trials and case-control studies, bcg vaccines may shed light on properties required of a tb va ... | 2014 | 26082111 |
complications following intravesical bacillus calmette-guerin treatment for bladder cancer: a case series of 22 patients. | intravesical bacillus calmette-guerin (bcg) therapy is an effective and widely used treatment for superficial bladder carcinoma. local complications are frequent whereas systemic complications are rare but can be serious, and their management is not well known. | 2015 | 26077036 |
effects of the fusion design and immunization route on the immunogenicity of ag85a-mtb32 in adenoviral vectored tuberculosis vaccine. | vaccines containing multiple antigens may induce broader immune responses and provide better protection against mycobacterium tuberculosis (mtb) infection as compared to a single antigen. however, strategies for incorporating multiple antigens into a single vector and the immunization routes may affect their immunogenicity. in this study, we utilized recombinant adenovirus type 5 (rad5) as a model vaccine vector, and ag85a (rv3804c) and mtb32 (rv0125) as model antigens, to comparatively evaluate ... | 2015 | 26076321 |

fecal volatile organic ccompound profiles from white-tailed deer (odocoileus virginianus) as indicators of mycobacterium bovis exposure or mycobacterium bovis bacille calmette-guerin (bcg) vaccination. | white-tailed deer (odocoileus virginianus) serve as a reservoir for bovine tuberculosis, caused by mycobacterium bovis, and can be a source of infection in cattle. vaccination with m. bovis bacille calmette guerin (bcg) is being considered for management of bovine tuberculosis in deer. presently, no method exists to non-invasively monitor the presence of bovine tuberculosis in deer. in this study, volatile organic compound profiles of bcg-vaccinated and non-vaccinated deer, before and after expe ... | 2015 | 26060998 |
mycolic acids, a promising mycobacterial ligand for targeting of nanoencapsulated drugs in tuberculosis. | the appearance of drug-resistant strains of mycobacterium tuberculosis (mtb) poses a great challenge to the development of novel treatment programmes to combat tuberculosis. since innovative nanotechnologies might alleviate the limitations of current therapies, we have designed a new nanoformulation for use as an anti-tb drug delivery system. it consists of incorporating mycobacterial cell wall mycolic acids (ma) as targeting ligands into a drug-encapsulating poly dl-lactic-co-glycolic acid poly ... | 2015 | 26055640 |
testing eurasian wild boar piglets for serum antibodies against mycobacterium bovis. | animal tuberculosis (tb) caused by infection with mycobacterium bovis and closely related members of the m. tuberculosis complex (mtc), is often reported in the eurasian wild boar (sus scrofa). tests detecting antibodies against mtc antigens are valuable tools for tb monitoring and control in suids. however, only limited knowledge exists on serology test performance in 2-6 month-old piglets. in this age-class, recent infections might cause lower antibody levels and lower test sensitivity. we exa ... | 2015 | 26051843 |
computed tomographic findings in cats with mycobacterial infection. | the objective of this study was to describe the ct imaging findings associated with confirmed mycobacterial infection in cats. | 2016 | 26045480 |
performance of a noninvasive test for detecting mycobacterium bovis shedding in european badger (meles meles) populations. | the incidence of mycobacterium bovis, the causative agent of bovine tuberculosis, in cattle herds in the united kingdom is increasing, resulting in substantial economic losses. the european badger (meles meles) is implicated as a wildlife reservoir and is the subject of control measures aimed at reducing the incidence of infection in cattle populations. understanding the epidemiology of m. bovis in badger populations is essential for directing control interventions and understanding disease spre ... | 2015 | 26041891 |
intravenous mycobacterium bovis bacillus calmette-guérin ameliorates nonalcoholic fatty liver disease in obese, diabetic ob/ob mice. | inflammation and immune response profoundly influence metabolic syndrome and fatty acid metabolism. to analyze influence of systemic inflammatory response to metabolic syndrome, we inoculated an attenuated vaccine strain of mycobacterium bovis bacillus calmette-guérin (bcg) into leptin-deficient ob/ob mice. bcg administration significantly decreased epididymal white adipose tissue weight, serum insulin levels, and a homeostasis model assessment of insulin resistance. serum high molecular weight ... | 2015 | 26039731 |
increased vancomycin susceptibility in mycobacteria: a new approach to identify synergistic activity against multidrug-resistant mycobacteria. | mycobacterium tuberculosis is wrapped in complex waxes, impermeable to most antibiotics. comparing mycobacterium bovis bcg and m. tuberculosis mutants that lack phthiocerol dimycocerosates (pdim) and/or phenolic glycolipids with wild-type strains, we observed that glycopeptides strongly inhibited pdim-deprived mycobacteria. vancomycin together with a drug targeting lipid synthesis inhibited multidrug-resistant (mdr) and extensively drug-resistant (xdr) clinical isolates. our study puts glycopept ... | 2015 | 26033733 |
correction: genomic analysis of a mycobacterium bovis bacillus calmette-guérin strain isolated from an adult patient with pulmonary tuberculosis. | 2015 | 26024365 | |
ifn-γ differentially regulates subsets of gr-1(+)cd11b(+) myeloid cells in chronic inflammation. | during chronic inflammation, prolonged over-reactive immune response may lead to tissue destruction, while immune suppression hinders tissue repair and pathogen elimination. therefore, precise regulation of the immune response is needed to avoid immuno-pathology. interferon-gamma (ifn-γ) is widely used in clinical treatment of inflammatory diseases. however, the underlying mechanism remains unclear. here, we evaluated the role of ifn-γ on cd11b(+)gr-1(+) myeloid cell differentiation and function ... | 2015 | 26021804 |
an inducible expression system for high-level expression of recombinant proteins in slow growing mycobacteria. | a novel protein expression vector utilising the inducible hspx promoter of mycobacterium tuberculosis was constructed and evaluated in this study. high-level induction of three mycobacterial antigens, comprising up to 9% of bacterial sonicate, was demonstrated in recombinant mycobacterium bovis bcg when grown under low-oxygen tension, which serves to enhance hspx promoter activity. recombinant proteins were efficiently purified from bacterial lysates in a soluble form by virtue of a c-terminal 6 ... | 2015 | 26021569 |
