Mycobacteriophage DS6A specific for the mycobacterium tuberculosis complex

摘要

Mycobacteriophage DS6A has been characterized and found to specifically infect all species of the TB complex, without any detectable infection of mycobacteria species other than those of the TB complex. DNA sequence analysis revealed several potential open reading frames, including one encoding a protein analogous to gp37 of mycobacteriophage L5 and a second encoding a protein with significant homology to the S. coelicolor DNA polymerase beta subunit. Based on the DNA sequence analysis, cloning sites can be identified for insertion of reporter genes, making DS6A useful as a reporter phage for specific detection and identification of species of the TB complex.
