Lung disease caused by nontuberculous mycobacteria (NTM) is an emerging infectious disease of global significance. Epidemiologic studies have shown the Hawaiian Islands have the highest prevalence of NTM lung infections in the United States. However, potential environmental reservoirs and species diversity have not been characterized. In this cross-sectional study, we describe molecular and phy...
Mycobacterium avium complex (MAC) species cannot be discriminated by the usual methods of biochemical identification of mycobacteria. This study showed that amplification by PCR of DT1 and DT6, two single copy sequences identified in the genome of M. avium serotype 2, the insertion sequence IS1245, found to be consistently present in M. avium strains and the heat-shock protein gene hsp65, follo...
Multilocus enzyme electrophoresis analysis was used to evaluate the Mycobacterium avium complex (MAC), M. paratuberculosis, and nine other mycobacterial species. The average number of alleles per locus was 2.8 for the 35 MAC and 2 M. paratuberculosis strains which represented 24 electrophoretic types (ETs) and two distinct groups. The M. avium group was resolved into 17 ETs and contained the M....
From the lipid fraction of a freeze-dried cell mass of a strain of the Mycobacterium avium-Mycobacterium intracellulare complex, a new glycolipid was isolated and was characterized as 5-mycoloyl-alpha-arabinofuranosyl (1-->1')-glycerol, mainly on the basis of nuclear magnetic resonance spectroscopy studies.
Direct PCR detection of bacteria in clinical samples is often hindered by the presence of compounds that inhibit the PCR. To improve and accelerate the diagnosis of Mycobacterium avium-M. intracellulare complex infections, an immunomagnetic PCR (IM-PCR) assay was developed. This IM-PCR procedure combines the separation of mycobacteria by antimycobacterial monoclonal antibody coupled to magnetic...
