This horizontal gene transfer often involves temperate bacteriophages and plasmids.

Nontoxic strains can acquire toxicity through a temperate bacteriophage.

Wolbachia also harbor a temperate bacteriophage called WO.

P1 is a temperate bacteriophage (phage) that infects Escherichia coli and a some other bacteria.

In this way, temperate bacteriophages also play a role in the spread of virulence factors, such as exotoxins and exoenzymes, amongst bacteria.

Lambda phage is considered a 'temperate bacteriophage': one whose genome incorporates with and replicates with that of the host bacterium.

Pasteurella phage F108 is a temperate bacteriophage (a virus that infects bacteria) of the family Myoviridae, genus Hp1likevirus.

Enterobacteria phage P4 (also known as satellite phage P4) is a temperate bacteriophage of the family Myoviridae.

Bacteriophage Mu or phage Mu is a temperate bacteriophage, a type of virus that infects bacteria.

The lytic life cycle of virulent bacteriophages is contrasted by the temperate lifecycle of Temperate bacteriophages.

Temperate bacteriophages integrate into the host genome at specific interrupted dyad symmetry sequences using the phage encoded enzyme integrase (see prophage integration).

Virulent strains of V. cholerae carry a variant of temperate bacteriophage called CTXf or CTXφ.

The genes for cholera toxin are carried by CTXphi (CTXφ), a temperate bacteriophage inserted into the V. cholerae genome.

These bacterial proteins form a small family that is additionally represented in Salmonella paratyphi A, the temperate bacteriophage u136 of Lactococcus lactis (ORF252-encoded protein) and a Shiga toxin-converting phage from E. coli .
