Mycobacterium virus Patience, also called Patience, is a bacteriophage that infects Mycobacterium smegmatisbacteria. The large difference between the GC content of this virus's genome (50.3%)[1] and that of its host (67.4%) indicate Patience likely evolved among bacteria of lower GC content but was able to infect M. smegmatis as well.[2] It is the only species of the genus Patiencevirus.[3]
