Abstract The aim of the presented research was to evaluate antimicrobial, anti-tuberculosis and antioxidant activity thiosemicarbazone derivatives. thermal stability degradation nineteen compounds were determined. results obtained in vitro tests indicate potential selected against Staphylococcus aureus , epidermidis Mycobacterium tuberculosis . Some turned out be active free radical scavengers ...

A patient with Mycobacterium abscessus lung disease was mistaken to have pulmonary tuberculosis with airway colonization by the non-tuberculous mycobacterium. Appropriate antibiotics were only given when the patient's signs and symptoms worsened while on anti-tuberculosis therapy. Despite treatment with a combination of antibiotics showing in vitro susceptibility, the pathogen persisted in the ...

Background Bovine tuberculosis (TB) is a disease which constitutes an important economic and zoonotic problem in Latin America. The etiological agent, Mycobacterium bovis, has several antigens described and well characterized. The M. bovis antigen 85B (Ag85B), encoded by fbpB gene, is the bacillus immunodominant antigen and promising target for vaccine and diagnosis development [1]. Ag85B combi...

Resistant C57BL/6 mice infected in the lungs with Mycobacterium tuberculosis and then therapeutically vaccinated with Mycobacterium leprae-derived hsp65 DNA develop severe granulomatous pneumonia and tissue damage. Analysis of cells accumulating in the lungs of these animals revealed substantial increases in T cells secreting tumor necrosis factor alpha and CD8 cells staining positive for granz...

Tuberculosis is a highly infectious disease. It usually infects the lung, but dissemination to different organs results in severe form of tuberculosis, i.e., disseminated tuberculosis. The situation becomes even more challenging when infection due multidrug-resistant strains Mycobacterium present case very rare one where 17-year-old Indian girl presented with headache, vomiting, cough expectora...

BACKGROUND Mycobacterium chimaera is a recently described species within the Mycobacterium avium complex. Its pathogenicity in respiratory tract infection remains disputed. It has never been isolated during cystic fibrosis respiratory tract infection. CASE PRESENTATION An 11-year-old boy of Asian ethnicity who was born on Réunion Island presented to our hospital with cystic fibrosis after a d...

The antigen complex of A60 of Mycobacterium bovis BCG was analyzed by different immunological techniques to assess its relevance to tuberculosis and the involvement of its components in the immune reactions elicited in humans by tuberculous infection. A60 is composed of about 30 components, of which 8 were identified by available monoclonal antibodies (lipoarabinomannan, a glycolipid, and prote...

Mycobacterial energy metabolism currently attracts strong attention as new target space for development of anti-tuberculosis drugs. The imidazopyridine Q203 targets the cytochrome bcc complex of the respiratory chain, a key component in energy metabolism. Q203 blocks growth of Mycobacterium tuberculosis at nanomolar concentrations, however, it fails to actually kill the bacteria, which may limi...

background and objectives: esat-6 (6-kdaearly secretory antigenic target) and cfp-10 (10-kda culture filtrate protein) have been described as dominant antigens recognized by t-cells and considered as virulence factors in mycobacterium tuberculosis . the aim of this study was to clone, express and purify recombinant esat-6 andcfp-10 proteins of m. tuberculosis in soluble form. materials and meth...

There has been considerable interest in the development of new anti tubercular agents particularly against multidrug resistance and extensively drug resistant strain of tuberculosis because mycobacterium species have developed resistant against currently used drugs. The currently use antitubercular drugs having toxic effect and long period of therapeutic treatment. Therefore, many researchers h...
