The mutant viral gene was dubbed v-src, and the normal chicken version c-src.

The viral form of the src gene is called v-src and the cellular form is c-src.

The subject bacteria are characterized by having a mutation in a gene chosen from a TetR gene, a LadR gene, a VirR gene, a MarR gene a MdrL gene, a MdrT gene and a MdrM gene.

The myc gene had previously been identified as a viral oncogene called v-myc.

Novel genetic variants of the V-Fos FBJ Murine Osteosarcoma Viral Oncogene Homolog (FOS) gene are described.
