Meaning and Definition
A bacterial plasmid responsible for the production of a colicin.
In microbiology, colicinogen refers to the genetic element (usually a plasmid) that enables a bacterium to synthesize colicins, which are protein toxins lethal to related bacterial strains, often involved in competitive interactions within microbial communities.

FAQ
Frequently Asked Questions
No. A colicin is the protein toxin. A colicinogen is the genetic element (usually a plasmid) that codes for and enables the production of that toxin.
Primarily in Escherichia coli and related enteric bacteria, but bacteriocinogen is a broader term for similar systems in other bacteria.
Yes, as they are often plasmid-borne, they can be transferred between bacterial cells through processes like conjugation, spreading the trait.
They are studied in microbial ecology (competition), plasmid biology, and have potential applications in typing bacterial strains or developing narrow-spectrum antimicrobials.
