F-prime bacterium

noun, plural: F’ bacteria
The bacterium possessing a plasmid containing the F factor and a part of the bacterial genome.
There are instances when the F factor incorporated in the chromosome of the Hfr bacterium loops out and becomes a plasmid. In certain cases, the looped-out plasmid not only contains F factor DNA but also a portion of the bacterial chromosome. This occurs when the excision from the chromosome is erroneous.
