Site-Directed Mutagenesis of the 19-Kilodalton Lipoprotein Antigen Reveals No Essential Role for the Protein in the Growth and Virulence of Mycobacterium intracellulare
1 Aug 1998
Abstract excerpt
The mycobacterial 19-kilodalton antigen (19Ag) is a highly expressed, surface-associated glycolipoprotein which is immunodominant in infected patients and has little homology with other known proteins. To investigate the pathogenic significance of the 19Ag, site-directed mutagenesis of the Mycobacterium intracellulare 19Ag gene was carried out by using a suicide vector-based strategy. Allelic replacement of the...
