Serovars of Mycobacterium avium complex isolated from patients in Denmark.

Analysis of Mycobacterium avium complex serovars isolated from AIDS patients from southeast Brazil.

The purpose of this study was to assess the distribution of Mycobacterium avium serovars isolated from AIDS patients in São Paulo and Rio de Janeiro. Ninety single site or multiple site isolates from 75 patients were examined. The most frequent serovars found were 8 (39.2%), 4 (21.4%) and 1 (10.7%). The frequency of mixed infections with serovar 8 or 4 was 37.8%. Among the 90 strains examined, ...

Heat Resistance and Virulence of Serovars of the Mycobacterium a Vium Complex

Pavlas, M.: Heat Resistance and Vinllence ofSerovars of the Mycobacterium avium Complex. Acta vet. Bmo 1997,66: 249-252. Heat resistance and virulence tested in chickens were investigated in 151 strains classified with the Mycobacterium avium complex. The highest differences in heat resistance between virulent and avirulent strains were found at 2-h exposure to 60°C. Under such conditions, 92% ...

Identification of various serovar strains of Mycobacterium avium complex by using DNA probes specific for Mycobacterium avium and Mycobacterium intracellulare.

Reference strains of the Mycobacterium avium complex (MAC) belonging to serovars 1 to 28 were examined with DNA probes (Gen Probe Rapid Diagnostic System for the MAC; Gen Probe Inc., San Diego, Calif.) specific for either M. avium or Mycobacterium intracellulare. This study revealed that the earlier designations of the MAC serovars, in which serovars 1 to 3 and 4 to 28 were regarded as M. avium...

SERA FROM SYPIllLI ATIC PATIENTS CROSS REACT WITH SPECIFIC GLYCOPEPTIDOLIPID AND WHOLE LIPID EXTRACT OF MYCOBACTERIUM AVIUM COMPLEX IN AN ANTICARDI OLIPIN ANTIBODY TEST

Isolation and expression of a gene cluster responsible for biosynthesis of the glycopeptidolipid antigens of Mycobacterium avium.

Bacteria within the Mycobacterium avium complex are prominent in the environment and are a source of serious disseminated infections in patients with AIDS. Serovars of the M. avium complex are distinguished from all other mycobacteria and from one another by the presence of highly antigenic glycolipids, the glycopeptidolipids, on their surfaces. A genomic library of DNA from serovar 2 of the M....
