253:, though others were found in other United States locations, India, and Japan. No distinct differences were found in the genomes of mycobacteriophage species from different global origins. Mycobacteriophage genomes have been found to contain a subset of genes undergoing more rapid genetic flux than other elements of the genomes. These "rapid flux" genes are exchanged between mycobacteriophage more often and are 50 percent shorter in sequence than the average mycobacteriophage gene.

221:(Figure 1). However, mutants can be readily isolated from some phages that expand their host range to infect these other strains. However, the molecular basis of host range depends on the behavior and presence of specific genes. This raises the probability of a correlation between gene phamilies and the preferred host.

A selection of 60 mycobacteriophages were isolated and had their genomes sequenced in 2009. These genome sequences were grouped into clusters by several methods in an effort to determine similarities between the phages and to explore their genetic diversity. More than half of the phage species were

Historically, mycobacteriophage have been used to "type" (i.e. "diagnose") mycobacteria, as each phage infects only one or a few bacterial strains. In the 1980s phages were discovered as tools to genetically manipulate their hosts. For instance, phage TM4 was used to construct shuttle
