A filamentous bacteriophage, of the genus Inovirus, is a type of bacteriophage, or virus of bacteria, defined by its filament-like or rod-like shape. It has only a few genes and is one of the simplest biological systems known. Filamentous phages usually contain a genome of circular single-stranded DNA and infect Gram-negative bacteria [1][2][3] and can reproduce without killing the host. The filamentous phage of Escherichia coli are the most productive phage in nature.
