Mycobacterium chimaera, a nontuberculous mycobacterium (NTM) belonging to the Mycobacterium avium complex (MAC), is an opportunistic pathogen that can cause respiratory and disseminated disease. We report the complete genome sequence of a strain, SJ42, isolated from an immunocompromised male presenting with MAC pneumonia, assembled from Illumina and Oxford Nanopore data.
BACKGROUND Most environmental non-tuberculous mycobacteria have been demonstrated to invade amoebal trophozoites and cysts, but such relationships are largely unknown for members of the Mycobacterium tuberculosis complex. An environmental source has been proposed for the animal Mycobacterium bovis and the human Mycobacterium canettii. METHODOLOGY/PRINCIPAL FINDINGS Using optic and electron mi...
A simple, modified formation for urea broth gave consistent, reliable results to aid in the differentiation of Mycobacterium species. In a study of 1,346 isolates representing 17 different species, tests read after 7 days were distinct and reproducible. The use of this test facilitates the identification of Mycobacterium species, such as M. scrofulaceum, the M. avium complex, the M. terrae comp...
The potentially pathogenic Non-Tuberculosis Mycobacteria (NTM) are emerging nowadays which result in pulmonary and non-pulmonary infections in human. This group of bacteria consists of at least 200 different species. While the pulmonary disease is the most common form of NTM infections, NTM can cause diffused infections as well as extrapulmonary infections in every organ, such as bone marrow, s...
Differentiation between Mycobacterium tuberculosis and M. avium is helpful for the treatment of disseminated mycobacterial infection in AIDS patients. This can traditionally be done by time-consuming biochemical tests or with Accuprobe. Previously, PCR restriction enzyme analysis (PCR-REA) of the 16S-23S rRNA gene spacer was shown to be able to identify a limited number of strains of Mycobacter...
Using molecular techniques, specifically, DNA-DNA hybridization in solution and measurement of the thermal stabilities of hybrids, we examined the genetic relationships among mycobactin-dependent mycobacteria and between such organisms and other (mycobactin-independent) mycobacteria. The mycobactin-dependent mycobacteria examined included five strains of Mycobacterium paratuberculosis, two wood...
The effectiveness of two major UV technologies against a highly prevalent species of Mycobacterium avium complex was investigated. Our study indicates that M. avium is much more resistant to UV irradiation than most waterborne pathogens and that it is one of the rare microorganisms that are highly resistant to both chemical and UV disinfection in water.
Modifications to the tube-agglutination procedure which Schaefer developed for serotyping of organisms of the Mycobacterium avium-M. intracellulare-M. scrofulaceum complex are proposed.
