background and objectives: hbha and mtb32c have been isolated from culture supernatants of mycobacterium tu- berculosis (m. tuberculosis) and mycobacterium bovis (m. bovis) and their immunogenicity previously studies have been confirmed. in this study, capability of constructed vector containing two mycobacterial immunodaminant antigens (mt- b32c-hbha), in producing new chimeric protein under t...

The distribution of 20 variable regions resulting from insertion-deletion events in the genomes of the tubercle bacilli has been evaluated in a total of 100 strains of Mycobacterium tuberculosis, Mycobacterium africanum, Mycobacterium canettii, Mycobacterium microti, and Mycobacterium bovis. This approach showed that the majority of these polymorphisms did not occur independently in the differe...

Mycobacterium bovis causes bovine tuberculosis and is the main organism responsible for zoonotic tuberculosis in humans. We performed the sequencing, assembly and annotation of a Brazilian strain of M. bovis named SP38, and performed comparative genomics of M. bovis genomes deposited in GenBank. M. bovis SP38 has a traditional tuberculous mycobacterium genome of 4,347,648 bp, with 65.5% GC, and...

La vacuna BCG es clave para el control de la tuberculosis. En ocasiones se observan eventos adversos sistémicos causados por Mycobacterium bovis BCG; usualmente asociados a inmunodeficiencia. Describimos seis casos clínicos niños vacunados con al nacer, complicaciones sistémicas post-vacunación.

PURPOSE The Mycobacterium tuberculosis complex comprises M. tuberculosis, M. bovis, M. bovis bacillus Calmette-Guérin (BCG) and M. africanum, and causes tuberculosis in humans and animals. Identification of Mycobacterium spp. and M. tuberculosis complex to the species level is important for practical use in microbiological laboratories, in addition to optimal treatment and public health. MATE...

The focus of our study is the synthesis and biological activity evaluation of a series of 4H-Pyran compounds and schiff bases fused 4H-Pyran derivatives which are known to possess a wide variety of biological activities. In this paper at first a simple and efficient one-pot synthesis of 4H-Pyran s from the three-component reaction between malononitrile, aldehydes, and active methylene compounds...

We report about a rare case of disseminated Mycobacterium bovis infection in a 61 year old female immunocompetent patient with involvement of the lung, the brain, the spleen and spine. The patient had intracerebral tuberculomas with paradoxical enlargement during the first weeks of therapy. We reviewed the data of our microbiological department and found five other patients with Mycobacterium b...
