The genus Mycobacterium is highly diverse and ubiquitous in nature, comprehending fast- and slow-growing species with distinct impact in public health. The plasmid-mediated horizontal gene transfer represents one of the major events in bacteria evolution. Here, we report the complete sequence of a 160,489 bp circular plasmid (pCBMA213_2) from an atypical and fast-growing environmental mycobacte...

atypical mycobacterium granulomatous skin infections are often accured by mycobacterium marinum, m. ulcerans, m. fortuitum, and m. avium colonies. skin infections probably originate from an environmental source such as contacting with aquatic animals, fish farming and swimming in the pools, and inoculate into skin through skin wounds, scratches, trauma, and surgery. the lesions appear as purple...

Protective potency of oil-treated cell walls of various mycobacteria against airborne infection of mice with a few cells of Mycobacterium tuberculosis H37Rv was compared with that of viable BCG. Although less potent than BCG cell walls, the cell walls of atypical mycobacteria of Runyon's groups I to IV protected against challenge by aerosol to some degree. Protection afforded by cell walls of H...

Atypical mycobacteria, also known as nontuberculous mycobacteria (NTM) includes acid-fast bacteria other than Mycobacterium tuberculosis. NTM can be isolated from a variety of environmental sources including water, food products, domestic animals, and soil; human exposure is typically from soil to the oral cavity and respiratory tract. Diagnosis of NTM is suspected in children less than five ye...

Tuberculosis continues to constitute the principal mycobacterial pulmonary disease. Control measures are known and their effectiveness limited mainly by social and economic factors. Other mycobacterial diseases are not so readily controlled owing to incomplete knowledge of epidemiology, pathogenesis and treatment. The Runyon classification given in table I developed as cultural character­ istic...

Mycobacterium chelonae is a rapidly growing nontuberculous mycobacteria, ubiquitous in the environment and mostly involved in skin, soft tissue and bone infections. An atypical, severe and multifocal dermatological manifestation of Mycobacterium chelonae infection in an immunocompetent patient is described here. The lesions completely resolved using a multidisciplinary approach. This case empha...

Bovine tuberculosis was last detected in cattle and pigs in the Czech Republic in 1995. Since March, 31, 2004 (Commission Decision No. 2004/320/EC) the Czech Republic has been included amongst states free from bovine tuberculosis within the European Union. The purpose of the present study was to evaluate results of intravital and post-mortem diagnosis of mycobacterial infections in slaughtered ...
