Definition

Noun: 1. The condition or state in which a bacteriophage (a virus that infects bacteria) integrates its genetic material into the DNA of its bacterial host without immediately destroying it. This integrated phage DNA, called a prophage, is replicated along with the host cell's DNA and can remain dormant for many generations.

Usage

• Lysogenicity is a specific biological state resulting from a viral infection.
• It describes a stable, non-destructive relationship between a phage and its bacterial host.
• The term is used in microbiology, genetics, and virology.

Examples

• The lysogenicity of the bacterial culture was confirmed by detecting the presence of prophage DNA.
• A key feature of lysogenicity is the potential for the prophage to later become active and enter the lytic cycle, destroying the host cell.
• Researchers study lysogenicity to understand how viruses can alter bacterial genetics and behavior.

Advanced Usage

• Temperate Phage: A bacteriophage capable of establishing lysogenicity. It is contrasted with a "virulent phage," which always destroys its host.
• Lysogenic Cycle: The process by which a temperate phage establishes lysogenicity. This cycle is an alternative to the "lytic cycle."
• Induction: The process that triggers a prophage to exit the state of lysogenicity and begin the lytic cycle, often in response to environmental stress on the host bacterium.

Variants and Related Words

• Lysogeny (n.): A synonym for lysogenicity, referring to the same phenomenon. Often used interchangeably.
• Lysogenic (adj.): Describing the state or a bacterium that is in lysogenicity (e.g., a lysogenic bacterium).
• Prophage (n.): The dormant, integrated form of a bacteriophage genome within the host's DNA during lysogenicity.
• Lytic (adj.): Pertaining to the cycle of viral replication that results in the destruction (lysis) of the host cell. This is the opposite outcome to lysogenicity.

Synonyms

• Lysogeny
• Prophage state

Antonyms

• Lysis (specifically in the context of the immediate destructive outcome of a viral infection)
• Lytic cycle

Noun

1. the condition of a host bacterium that has incorporated a phage into its own genetic material
   • when a phage infects a bacterium it can either destroy its host or be incorporated in the host genome in a state of lysogeny
